Update information for manual updates (Windows) via MSIX file
When updating the app (version 1.4.0 or earlier) to a newer version (version 1.4.12 or later), a fresh installation is required once due to a change in the certificate.
Note: This will result in the loss of your call list.

The notice about LDAP contacts that could not be loaded now only appears after a manually triggered update of the contacts.
Bug fixes
The notification about a new message always appeared in English.
If an outgoing call had been answered with the SIP message 480 Temporarily Unavailable, the call was retained in the operating system. On the next call, a warning was therefore displayed that a call still in progress would be ended.
Call setup during a network change was not successful.
There was no audio connection on the fourth simultaneous call.
For an incoming call to a group, the group name was only displayed in the call details.
When the app was started, a failed contact list query was reported although the contacts were still being downloaded.
If the app received a message in the background while the display was locked, the identity page was opened instead of the messages page when the notification was tapped after unlocking.
Transfer without announcement failed if the call partner was on hold.
After a successful transfer without announcement, the end of the call by the call partner was reported in addition to the transfer itself. This additional message no longer appears.
While a voicemail was playing, display errors could occur.
