Changes V7.8.0.8453

Improvements

• Database accesses to the UserStates have been given a low timeout and logging has been extended so that timeouts are logged by the SQL database.
• Performance of the user list query via the admin interface for users who have never set a presence has been optimized by removing unnecessary queries.
• When forwarding the client to the administration server, the name check will be non-case-sensitive in future.
• "Voice Services". Support for analog devices from Grandstream.

Bug fixes

• Fixed a problem with SIP federation that initially no contact data such as display name or phone numbers were exchanged.
• Fixed a problem where unknown data sources were displayed in the ProCall Client for Windows.
• Fixed a problem where the ProCall Client for Windows no longer automatically connected to the UCServer after Windows hibernation.
• A problem with appointments on the UCServer has been solved that these could not be deleted in the database under certain circumstances.
• When restoring a line to a user account in the UCServer administration, an error message regarding ProCall Voice Services could appear under certain circumstances, although this service is not activated.
• A problem has been fixed where, when a call is forwarded to a SIP extension, the forwarding destination is not transmitted in the form of a phone number but a SIP address. As the information could not be evaluated correctly, incorrect contact information may have been entered in the journal.
• If a key was administratively configured in the UCServer administration in the settings of a group, tab Keys and the name contained a special character, the UCServer service crashed when writing this value in the ExtensionName field of the Active Directory. The problem has been fixed.
• "Voice Services". When removing the last VoiceServices end device, UCAdmin crashed. The error has been fixed.
• "Voice Services". The uaCSTA server can be specified in the UCServer Admin under "End devices" so that it is rolled out to the end devices. If one of the fields was not filled in, an error message appeared when the "End devices" area was called up."Voice service not available". The problem has been fixed.

Changes V7.7.4.7908

Bug fixes

• Potential crash cause fixes taken from MetaDirectory code.

Changes V7.7.3.7766

Improvements

• It is detected if a Redis subscriber connection is dropped. If this is the case, all Redis connections are then reinitialized to ensure a stable connection to the Redis database.

Bug fixes

• Longer contact names were truncated when automatically switching contacts in the chat window. The bug was fixed
• For softphone connections to Mitel MX-ONE PBXs, the 'MNS Pickup' behavior was improved. In a customer installation, it was observed that after the pickup process, the ring tone ('Ringback') did not go off and the connection time was not counted up in the journal. 
• Reverted changes that caused connection failures to Redis over TLS.
• Fixed a problem that could cause UCServer DataCenter to crash (appcrash) under unfavorable conditions when starting the service or after connecting to Redis.
• A problem was solved with the logon of ProCall clients to the UCServer in the combination of local file-based user administration and Windows domain authentication.

Changes V7.7.2.7649

Improvements

• In the Audio/Video Wizard of the ProCall client for Windows, the help for the item "Ringing tone" has been added.
• The debug log in UCServer has been extended with details about logon errors related to NTLM and Kerberos.

Bug fixes

• Several crashes of the ProCall client for Windows have been fixed.
• Resolved an issue with NTLM login when the sAMAccountName and UPN were different in file-based user management.
• A problem was solved when the default directory for local databases (SQLite) was changed in UCServer. In this case, exporting the data was no longer possible.
• In the Me area of ProCall client for Windows, in the context menu of the calendar icon, appointments that you have hidden via the totals bubble are displayed with a designated icon.
• If the option 'Cancel call forwarding' was set for 'Call forwarding' via a presence profile, the call forwarding continued to exist when the presence state was reached.
• Shared contact folders can be reattached to ProCall client for Windows via EWS or MAPI.

Changes V7.7.1.7401

Bug fixes

• Fixed several client and server crashes.
• Hundreds of error mails are no longer produced in case of license problems towards UCConnect.
• In the Firstcom Europe SIP connection, a problem with the recognition of calls and their assignment to users in the journal has been improved.
• On the client for Windows the deletion of a call forwarding was improved if two lines with the same phone number (one TAPI and one softphone) were forwarded to the same destination phone number and no call forwarding profile was used for it. Until now, the call forwarding had to be deleted on each line individually. In the future, there will be another menu item that shows the number of lines whose call forwarding will be cancelled when the corresponding button is pressed.

Änderungen V7.7.0.7299

New functions

• When booking ProCall Voice Services, a new submenu appears in the UCServer for setting up ProCall Voice Services, the new cloud PBX from estos with connected SIP trunk. The functions and further information on ProCall Voice Services can be found in the support portal for ProCall Voice Services.

Improvements

• The SIP profile for "HFO" has been renamed to "Gamma".
• When creating a new line group for an MX-One PBX, the default settings have been changed. These cause that in the future in the SIP REFER also the CONTACT header is present.
• At the suggestion of a PBX manufacturer, the SIP RTP profile for outgoing softphone calls has been adapted if TLS/sRTP is set. Previously the RTP profile was "RTP/SAVPF".
  
  - In the future, the RTP profile "RTP/SAVP" will be used for encrypted outgoing softphone calls.
  
  For unencrypted outgoing softphone calls, the RTP profile remains unchanged at "RTP/AVP". Background: the RTP profile "RTP/SAVP" is more widely used by PBXs and border gateways than the "RTP/SAVPF" profile. All PBXs tested with TLS/sRTP answer with "RTP/SAVP", even if "RTP/SAVPF" is offered in the SDP-Offer.
• If the TLS socket was disconnected during an encrypted softphone connection, the affected line was "grayed out" for some time until a new register reset the line in the time cycle. In the future, when a TLS socket disconnect occurs, a new register will immediately attempt to re-establish the connection. Note: undesired socket disconnects can occur, for example, if a local NAT device has set short socket timeouts during softphone registrations over the Internet. This can be remedied by a correspondingly short "NAT refresh" cycle in the properties of the softphone line group.

Bug fixes

• Fixed two problems with changing call forwarding by another user when there was one TAPI and one softphone line with the same phone number. If the other user tried to delete the existing call forwarding of his colleague, this was only successful on the first line. Subsequently, if only one of the two lines was diverted, the menu entry for deleting no longer appeared.
• If a regular expression was used in a softphone line group to transform the register user name, only the short number was displayed after saving in UCServer Administrator if a matching location was configured. In the future, the canonical number will also be displayed in this case.

Update V7.6.2.7071

Bug fixes

• Fixed various crashes of the UCServer.
• Fixed an issue that in rare cases could cause the server to hang ("freeze").
• In a customer environment, a sporadic crash of the server was observed, which could occur after a longer period of operation. The crash at this point was fixed and a corresponding debug output was generated.
• If a line was configured for a user under "Other lines of the user" (1st phone, 2nd phone), another line icon (e.g. VideoChat) was marked with an exclamation mark in the Favorites on the client for Windows and signaled as disturbed. This problem has been fixed.

Deployment of mobile apps – end of life

• This affects the use of the mobile apps within a PBX Call Assist 3 installation as of 01/01/2023. These can therefore no longer be used in a PBX Call Assist 3 environment from this date.

Update V7.6.2.6932

New features

• Microsoft Teams presence integration now supports web proxy connections:
  https://support.estos.de/en/procall-enterprise/procall-integration-in-microsoft-teams/inbetriebnahme-procall-integration-in-microsoft-teams#InbetriebnahmeProCallIntegrationinMicrosoftTeams-WebProxyUnterst%C3%BCtzung

Improvements

• Mouse wheel scrolling in the client for Windows monitor has been improved. A problem with skipping a line in the monitor while scrolling has been fixed.
• In the MAPI connection of the client for Windows, a display problem in the folder selection was fixed: In some scenarios, folders were displayed twice.

Fehlerbehebungen

• A crash of the UCServer when blindly forwarding softphone calls was fixed.
• Fixed a problem on UCServer that with "Windows Authentication" and local file-based user management in UCServer, users could not log in if the users were created in user management without a domain identifier (or even other differences in the user name), but log in to their workstation with one.

Deployment of mobile apps – end of life

• This affects the use of the mobile apps within a PBX Call Assist 3 installation as of 01/01/2023. These can therefore no longer be used in a PBX Call Assist 3 environment from this date.

Update V7.5.2.6434

Improvements

• The memory, processing power, and bandwidth requirements for screen sharing have been reduced by keeping the screen sharing resolution unchanged, but sending fewer frames per second (fps). This is especially important for larger monitors when the target system has significantly less perfomance compared to the sender. It has been reported in some cases that target systems can be overloaded to the point of crashing during screen sharing.
  The adjustment fixed the tracked problems without noticeably decreasing the quality of the screen sharing.
• Via the profiles in the UCServer administration or the ADM(X) templates, the setting "General – Behavior – Show speech bubble for – Appointments" can be preset on the ProCall client for Windows.
• A problem was fixed when creating a softphone line group, if the phone number of a line is taken from the user name of the SIP registration. If a range was specified when creating the lines (e.g. 120-125), the lines were created as expected, but all lines had the phone number '120-125'. In the future, each line will be assigned its own phone number again (e.g. the line with the SIP user name 120 will get the phone number 120).
• There is an improvement when applying the softphone location settings. At the item 'PBX' – 'Formatting' – 'Remove exchange code' there is the option 'Ignore ConnectedID'. The improvement causes a ' ConnectedID' signaled by the PBX (e.g. a PAI) to be ignored in the future. This option can be helpful as a last resort if the signaled PAIs are faulty and the problem cannot be solved by settings in the PBX or by location rules.

Bug fixes

• Resolved a problem on the ProCall client for Windows when the user does not want to log in automatically, but enters his username and password manually, but does not save the password: Users who do not save their password will now get the reconnect dialog to enter a password when the client is restarted. No automatic reconnect without password is performed.
• Fixed a bug in the ProCall Client SDK that the function asnAbsentStateGetUser did not output current user presences, but always iPresenceState = 0.
• Fixed a problem that when making a parallel call to an extension monitored by TAPI and softphone, a call that was answered on the softphone line, the TAPI capabilities were displayed in the call window. Therefore the call was no longer controllable.
• Fixed a bug in the ProCall client for Windows that when using the "Open calendar..." function, too many connections were established to the exchange server. This fix affects the ÈWS connection to Outlook.
• A problem with all-day appointments in the speech bubble has been solved.
• A problem was solved in the MS Teams presence integration when Busy on Busy was active on the ProCall client and the screen was split in the Teams client. As a result, Busy on Busy was canceled.

Update V7.5.1.6275

Update V7.5.0.6167

Update V7.4.2.5993

Update V7.4.0.5782

Update V7.3.5.5608

New functions

• ProCall integration in Microsoft Teams: There is now an option to match presence between ProCall Enterprise and Microsoft Teams. For more details see ProCall integration in Microsoft Teams.

• In softphone conferences, participants can hear short beeps when a participant joins or leaves the conference.

Improvements

• The matching of user names during the ProCall integration with Microsoft Teams can now also be performed manually via a CSV file if the user names in Azure AD and in the UCServer user management are different. For details see Start-up ProCall integration in Microsoft Teams
• In the UCServer management, the item "Integration in Microsoft Teams" now shows how many users were found in Azure AD and how many are activated in UCServer for the Teams integration and assigned to the user in Azure AD.
• The test for Microsoft Teams presence integration in UCServer management is now performed with the user specified in User Consent to exclude incorrect tests, such as with service accounts.
• The softphone profile name "C+ITEC AG" has been changed to "Firstcom Europe AG".
• For public permissions between users, the first and last name is now transferred in addition to the display name. So if there is no picture in the avatar, the abbreviation is formed from the first letter of the first name as well as the last name.
• When loading administrative content from the monitor or favorites where the template file has been placed on a web server, the access method has been updated to better handle a TLS connection to that web server.
• Via the UCServer administration "Events -> Delete log files" the logs of the Microsoft Teams integration are now also deleted.

Bug fixes

• Fixed a problem with Microsoft Teams integration when different IP address or port was set on UCServer for ProCall client connection.
• The SIP softphone line status is now automatically updated if there was a SIP transport protocol change in the line group.
• The problem with the Teams presence integration with hanging presences was resolved when there was an unexpected loss of connection to the Microsoft Graph API on the UCServer.
• Resolved an issue with the recognition of certain Jabra headsets (such as the Jabra Pro 935), with which call control is now also possible.
• Fixed a UCServer crash when the media server logging level was changed in UCServer management. The logging level of the media server is changed in the UCServer administrator under "General – Events – Media server events". Since changes in this location can have a significant impact on the performance of the media server, changes should only be made after being requested to do so by support.

Update V7.3.4.5515

Bug fixes (HOTFIX)

• A problem with the update service has been fixed. For details see Update service can no longer connect to server.

Update V7.3.4.5457

New functions

• ProCall integration in Microsoft Teams: There is now an option to match presence between ProCall Enterprise and Microsoft Teams. For more details see ProCall integration in Microsoft Teams.

  

  In ProCall Enterprise version 7.3.4, the feature is only available as part of a public field trial: This means that the feature can be used, but there may still be issues that will be resolved in this field trial. It is released as of version 7.3.5.

Improvements

• The connection of the ProCall client for Windows to MetaDirectory has been improved in connection with the user administrations available in MetaDirectory.

Bug fixes

• A bug in the UCServer administration was solved that the activation of "Open federation" was not saved there.
• Fixed a ProCall client for Windows crash related to calls to a parallel-switched line.

Update V7.3.3.5345

General information

• As the federation service "ngn21" will be switched off on 31/12/2021, the service ngn21 has been completely removed from the software.
  Background information can be found at https://support.estos.de/en/procall-enterprise/abschaltung-von-ngn21-beta-ab-1-januar-2022
• Since the SMS provider Sophos MCS is no longer available, it has been removed from the software.
• Since the interface of the SMS provider www.smskaufen.de changed to an incompatible version after the takeover by cm.com, this provider was removed from SMS dispatch.

New functions

• A new softphone profile was created for connection to Starface telephone systems (appliance, cloud and VM). The implementation was successfully completed with extensive testing. This includes incoming and outgoing calls, blind transfer ringing, blind transfer connected, consultation, call waiting, toggle, consultation transfer, three-party conference and pickup.
  • PBX-specific configuration: Setting up softphone functions (SIP) for STARFACE Cloud PBX – connection instructions
  • Supported telephony functions for ProCall Enterprise with STARFACE Cloud PBX
• The Client for Windows supports two new kuando Busylight models by Plenom:
  • Busylight Alpha Model 2
  • Busylight Omega Model 2

Improvements

• In the UCServer administration, the interfaces for SIP federation have been adapted.
• The behavior of SIP federation with Innovaphone PBXs when the connection between the PBX and the UCServer is disconnected has been improved.
• In UCServer Administration under "Licenses", the "Used" column for UCConnect Mobility Services displays the number of mobile devices currently logged in via Push and no longer the number of users who are allowed to use apps.
• In the Client for Windows, the display of the "Forwarded from:" information has been improved when it is not a (dialable) phone number, but names such as "SIP45". Previously only the dialable part was displayed, in our example "45". Now the whole information is displayed.
• The journaling of pickup calls to the provider NFON has been improved for softphone connections. If a call was picked up by another user, it was possible that the journal of the "picked up" subscriber did not show who had received the call (blue journal entry with "spoken to" information).

Bug fixes

• In certain system environments the media server could not be used. This concerns systems that do not provide an SSE processing unit on the processor side (CPU). In the error case, the Media Server crashed in libcrypto-10.dll, no successful softphone startup could be performed. The system requirements for the Media Server have been changed accordingly. As a workaround, this DLL is also available as a "no-SSE2" patch variant. However, it is recommended to use systems with SSE computing unit, because with this DLL certain computing operations are emulated on the software side, which results in an increased consumption of CPU computing power and therefore fewer subscribers can make calls simultaneously.

• Fixed an issue with the softphone connection to OD Cloud that resulted in one-sided audio after connecting a consultation.
• Fixed a problem with user activation/deactivation in AD snapin.
• Fixed a problem in UCServer setup when trying to import UCConnect licenses.
• Fixed a problem in UCServer administration when ProCall Meetings licenses expired when trying to edit users.
• Fixed a problem that in rare cases the UCServer service could not be terminated because existing socket connections were not terminated.
• A problem with DATEV integration has been fixed, where dialing from the DATEV workstation (client view) with multiple assignment of a phone number within the replicated dataset leads to ProCall dialing with a different addressee than transferred by DATEV.
• If the phone calls of a mobile device were controlled via Bluetooth with the Client for Windows, all calls were hung up by a waiting second call in case of an error. The behavior was observed when the user had activated a "Busy on Busy" or a "Do not disturb" on the Client for Windows. Now, as expected, only the waiting second call is rejected.
• A confusing display of softphone lines in the server administrator has been fixed. When a line group was newly created, lines might have been displayed twice even if they were created only once. The duplicate display did not affect the function of the server, but it was confusing. After restarting the server administrator, the display was correct.
• Fixed a problem in the Client for Windows with the "Actions" related to call forwarding. If the action "Cancel all call forwarding" was set for the event "When logging on to the server" and there were several lines with the same phone number, the call forwarding were not removed from all lines.
• For outgoing calls with the Client for Windows, certain service features ("buttons") were offered even if the PBX did not support them. However, for incoming calls, the buttons were displayed correctly. The problem has been noticed on an Alcatel OXO PBX that does not support Blind Transfer in connected state (Blind Transfer Connected).
• Manual configuration changes in .\estos\UCServer\config\eucwebconfig.json were overwritten when the server was restarted and were thus discarded. This problem has been fixed.

Update V7.3.2.5199

New functions

• As the federation service "ngn21" will be switched off on 31/12/2021, the configuration has been removed from the UCServer administration. An already configured service will continue to work until the time of shutdown.
  In the next maintenance release, ngn21 will be completely removed from the software.
  You can find background information under https://support.estos.de/en/procall-enterprise/abschaltung-von-ngn21-beta-ab-1-januar-2022

• The audio/video wizard of the ProCall client for Windows is now also located in the main menu ("..." menu in the top right corner of the client or by right-clicking on the ProCall systray icon) and can be called there.
• The UCServer Administrator has been extended to allow filtering in the "Line groups / Softphone registrations" dialog, e.g. to search for specific lines.
• The "Pickup" feature has been implemented for connections to the vPBX cloud provider Placetel. Currently (as of 12.11.2021), this feature is not yet offered by Placetel in the "Standard" tariff, but it may be available soon. If you have any questions about this, please contact Placetel. 

Improvements

• With permission level "public" the contact picture and the note of the users are now displayed again.
• The ProCall Enterprise installer can no longer be run incorrectly if a ProCall Business is already installed. ProCall Business must be uninstalled first.
• Under Windows 11, the layout of the ProCall Client for Windows has been adapted to the Windows 11 design principles. For example, the corners of the windows of the client are round.

• For connections to the vPBX cloud provider Placetel, the behavior of internally forwarded calls has been improved. The destination participant receives a SIP diversion info that contains the forwarding participant. This is signaled in the case not with the phone number, but with a string from the registration data. Since the user does not know this data, the stored phone number will be determined in the future and displayed as "forwarded by:", if available.

• For connections to the vPBX cloud provider Placetel, the behavior for incoming calls with suppressed phone number has been improved. In this case, we receive an "anonymous" in the "From:" as usual, but a P-Asserted (PAI) is additionally signaled with the own phone number. Therefore, the own phone number was displayed as the sender of the call. In the future we will only show "call number unknown" for suppressed call numbers and ignore a PAI with the own call number.

Bug fixes

• Security risk elimination: https://nvd.nist.gov/vuln/detail/CVE-2018-1285
• Fixed a translation error in the ProCall client for Windows in TextChat. Forwarded messages displayed "Forward" instead of "Forwarded". Also, the icon was adapted to the design of the ProCall Client.
• Fixed an issue where a ProCall Business license could be incorrectly entered into ProCall Enterprise.
• Fixed an issue with the ProCall client for Windows that very rarely caused the ProCall client to "freeze" when using Plantronics/Poly headsets.
• A problem in the UCServer administration was fixed. If the default path to the log files was changed, it was no longer possible to view the logs in UCServer Administration in the "Server events" item.
• Fixed a display error in ProCall client for Windows. When searching for a phone number that was not resolved in any data source, unreadable XML code was displayed in the tooltip of the search result.
• Fixed an issue in ProCall Client for Windows that caused the client's systray icon to blink red-gray on incoming call. The gray has been removed, and it now flashes red-orange again.
• Fixed a display error in ProCall client for Windows. When searching for a phone number that was not resolved in any data source, it was displayed that the unknown contact was "Available via federation". This display was removed.
• Fixed a rare issue where settings were lost or UCServer administration crashed when setting up a softphone line group.

Update V7.3.1.5076

New Features

• Microsoft Windows Server® 2022 and Microsoft Windows® 11 have been added to the system requirements. Details can be found here: ProCall 7 Enterprise system requirements.

• A revised SDK from the manufacturer has been implemented for the Windows client for call control with Jabra headsets. The SDK offers new possibilities and bug fixes. The previously used "Jabra Native HID API" (JabraNativeHid.dll version 1.4.308.0), has been updated to the current "Jabra SDK" (libjabra.dll version 1.8.8.5). All call control features implemented for ProCall were retested in the process.

  • This includes mute/activate microphone
  • Accept call
  • Reject call
  • Hang up connected call
  • Hold call, retrieve call
  • Accept second call (call waiting)
  • Reject second call
  • Toggle calls
  • Hang up the connected second call
• Furthermore, the list of tested Jabra headsets was extended. The tests were successfully completed with the Jabra headset types Engage 75 (via USB docking station) and Evolve2 65 (via BT dongle Link 380).

Improvements

• For public permission levels between users, the business phone numbers of users are now displayed.

• Help texts have been adapted in the UCServer online help.

• When installing the UCServer update, additional indexes are created to improve the performance of the chat.
• Improvements have been implemented in the softphone journal for "pickup" (fetching a call). The subscriber from whom a call was "picked up" now sees the corresponding journal entry in blue font. In the journal browser, the "Talked to" field can be used to determine who picked up the call.

• A server-side improvement has been implemented for softphone environments that do not provide forwarding information by the PBX for consultation calls. In this case, the consultation destination may not recognize when a transfer has been performed, as the old call contacts are still displayed. The forwarding information is now provided within the server as long as the forwarding participant and also the consultation target via softphone are on the server. During the transfer, the connected party display updates, and the "Holds:" party display (if present) is replaced with a new "Forwarded from:" display. If forwarding information is provided by the PBX, it takes precedence.

• The behavior of the Call button in the call window has been improved so that a new call cannot be initiated immediately after a previous call to prevent an unwanted callback.

Bug fixes

• Fixed a problem with the PCAP logger when the SIP softphone registrar was configured by FQDN (i.e. not by IP address). In some cases the logger could not assign the trace information to the lines and therefore did not record a call direction. The PCAP logger can be used to record special SIP softphone traces in Wireshark format.
• Phone number changes (Business, Business 2, Private, Mobile, Pager) in user management in UCServer Admin were not applied if a page other than "Phone numbers" was selected when clicking OK.
• Fixed a UCServer crash.
• Fixed an issue of the Multiline TSP not reconnecting to the attached UCServer when the UCServer is restarted.
• Fixed a rare crash of the ProCall client for Windows when it tries to initialize a microphone at startup but no default microphone is set yet.
• If the telephony service is restarted on the UCServer, then Remote Office, which was activated by users, will no longer be deactivated.
• An accepted and then (blindly) forwarded second call sometimes displayed a 'Hold' participant for the forwarding destination, although this should only be displayed for an enquiry transfer. Therefore, in this case, the held party of the first call was sometimes displayed, which, however, has no relevance for the destination party.
• Fixed an issue that the setting in the "Make appointments available to the system" profile was not transferred to the clients.

Update 7.2.3.4839

Improvements

• For the public permission level between users, discrepancies between the official documentation and the behavior of the software have been fixed. The behavior is now based on the existing documentation (for details see client help in the "Permissions" item or https://help.estos.com/help/en-US/procall/7.2/ucclient/dokumentation/dialogs/IDH_DLG_CHALLENGEREQUEST.htm)
  Furthermore, the visibility of the contact picture in the public permission level has been removed.
• Improved the behavior of softphone users who wanted to make a call to a Skype for Business user. Skype for Business could not handle certain a-lines in the SIP sdp of the ProCall softphone. The corresponding lines are now filtered out.

Bug fixes

• Fixed a permission problem when monitoring, setting call forwarding, or picking up calls from "additional lines" if they were not assigned to a user.
• Resolved an issue that after restarting the UCServer and re-logging in all clients, their idle/inactive presence from before the restart was no longer displayed. Instead, these users were displayed as green/present. Now the appropriate presence, such as idle, is displayed again.

Update 7.2.2.4754

Improvements

• A more tolerant processing of the Diversion header has been implemented for softphone connections to Panasonic PBXs. Previously, a missing 'sip:' prefix was classified as incorrect and therefore discarded. Now Diversion headers without 'sip:' prefix are also processed. These are then displayed in the client as "Forwarded from:".
  Example with 'sip:' prefix: "Diversion: Mustermann, Max <sip:302@10.1.10.10>;reason=unconditional".
  Example without 'sip,:' prefix: "Diversion: Mustermann, Max <302@10.1.10.10>;reason=unconditional"

• Improvements to the softphone's caller ID and pickup journal have been implemented.
  • If the PBX does not provide a legible phone number (e.g. "iuziuziu_oioi") in the PAI during pickup, the pickup number is preferably determined by the server. Previously, the pickup number was only determined by the server if a PBX did not supply a call number of the connected subscriber (PAI or similar).

  • In some cases, the number of the pickup destination was displayed in the Windows client with the prefixed feature code as 'Forwarded by' for the pickup subscriber. This meant that no contact could be determined. Now the prefixed feature code is removed and the canonical number is determined internally via location data. Therefore the correct number and the contact of the subscriber (if available) can be displayed, from which was fetched.

  • If a call is picked up or answered by another phone, the called subscriber receives a 'Cancel' from the PBX. If the PBX provides a matching reason code in the 'Cancel', the call is no longer displayed as 'unanswered' in the Journal Browser, for example. Either Q.850 formatted reason codes (cause=26; text="Non selected user-clearing") or SIP formatted reason codes (cause=200;text="Call completed elsewhere") are supported. These reason codes are widely used, but there are also implementations that do not provide a reason code in the 'Cancel'.

• A more tolerant processing of the PAI (P-Asserted-Identity, cf. like 'Connected Number') was implemented. During a 'ReInvite' a PAI with an empty domain was transferred, whereby a subscriber with an unknown number ('anonymous') was then displayed in the call window. Now numbers received in such a PAI without domain are also processed (e.g. 'P-Asserted-Identity: sip:00815136856177@').

Bug fixes

• Several crashes of the ProCall Client for Windows have been fixed.

• Rarely occurring disconnections during softphone calls were fixed. In case of an error, a call was hung up after 2 minutes with "Timeout connection setup".
   
• Fixed an issue in the chat window of chat rooms that the presence of contacts was not displayed if they were not in the favorites/monitor.
   
• Fixed an issue with UCServer administration in the Lines section that caused the administration interface to rarely hang when lines were activated.
   
• Fixed a rare crash of the ProCall Client for Windows during a screen share.
