Preparations

Preparing the PBX for Remote Access

• Activate "Enable dealer access via internet" in "Settings -> Remote Configuration" on the PBX.
• If using method 2 you also have to define a remote switching number as well as an external PIN.

Registering the PBX in ARA

• Go to "Registrierte TK-Anlagen" (registered PBXs)
• Press the "+"-symbol to register a new PBX.
• Enter at least the serial number, a name and the type of PBX of which you want to access.

Activating remote access

Method 1: Activation by any internal phone

• Tell your customer to dial the following sequence on any internal phone:  ##8 Admin-PIN | Subadmin-PIN | Benutzer-PIN * 91 # (example: ##8 471208* 91 #)
• Click the refresh- (next to the "+"-symbol) and then the "Verbinden" (connect)-button in ARA.

Method 2: Activation by the dealer from a distance

• Dial the previously configured remote switching number from any external phone.
• After the switching tone enter the following sequence: ##8 external PIN * 91 # (example: ##8 471108* 91 #)
• Click the refresh- (next to the "+"-symbol) and then the "Verbinden" (connect)-button in ARA.

Data privacy

Auerswald takes the protection of personal data very seriously. Please read the internet privacy statement and the general terms and conditions.

The following SD cards were tested and released for the COMmander VMF module:

ISDN-systemphones receive the time/date from the PBX.

If the PBX operates using an external ISDN line, time and date is automatically set after each ISDN call. However, if the PBX operates using only an external VoIP- or analog connection, time and date must either be configured manually or automatically set via NTP-server (internet access or a local NTP-server required).

The number of system telephones depends on the power consumption of the existing devices. The maximum power consumption at the internal S0 must not be exceeded.

Available power: max. 4 W per internal S0 bus (all telephone systems with internal S0 bus except COMpact 2204 USB and COMpact 3000)

Required power of the system phones:

• 1 COMfortel 1200 requires max. 2 W
• 1 COMfortel 1400 needs max. 2 W
• 1 COMfortel 1600 requires max. 2 W
• 1 COMfortel 2600 without power supply unit requires max. 2 W
• 1 COMfortel 2600 with power supply unit XT-PS required 0 W
• 1 COMfortel 2500 without power supply unit requires max. 2 W
• 1 COMfortel 2500 with power supply unit XT-PS required 0 W
• 1 COMfortel 1500 requires max. 2 W
• 1 COMfortel 1100 needs max. 2 W

Available power at the internal S0 bus of a COMpact 2204 USB: max. 2 W.
Power available on the internal S0 bus of a COMpact 3000 ISDN/analogue/VoIP: max. 2.5 W.

Depending on the constellation, various telephone combinations are possible on the COMpact 2204 USB or COMpact 3000 ISDN/analog/VoIP, e.g. (max. 2 system telephones):

• 2 x COMfortel 2500 with plug-in power supply
• 1 x COMfortel 1500 and 1 x COMfortel 2500 with power supply
• 1 x COMfortel 1100 and 1 x COMfortel 2500 with power supply

COMfortel 2500 with key extension COMfortel Xtension30 or COMfortel 2600 with key extension COMfortel Xtension300 can only be operated with the power supply unit COMfortel XT-PS.

A static IP address of http://192.168.1.111 is preset in the delivery state. The access data:
User name: admin
Password: admin
The current IP address can be queried on an ISDN telephone using the code ##8*941#.

The IP address is only displayed on the directly connected ISDN telephone, not on the internal S0 bus of our telephone systems.
Info: Display messages are used
COMmander Business and COMmander Basic.2 only: A replacement option is the automatic callback from the VoIP/ISDN gateway. With this callback, the IP address is then transmitted as the phone number.

Recommended action for systems possibly affected by hacker attacks:

1. Deactivate all port forwarding to the ICT system!
2. Check the log and make sure that the logins are traceable
3. Change the username, PIN and admin password
4. Check whether there are newly created sub-admins, users, participants or groups and change the passwords
5. Change passwords for public VoIP providers
6. Check call deflection

Check the following points for all profiles and properties (users, participants, groups, etc.):

1. Check the dialling privileges
2. Check parallel call
3. Check call deflections
4. Check voicemail boxes, check activation of remote control and change PINs
5. Check the deputy functions of the voicemail boxes and the registered destinations
6. Check Follow-Me settings

Check other configurations:

1. Check whether remote access by telephone (switching functions remotely by telephone) is active. Change PINs or, if unused, switch them off
2. Check automatic reception, check activation and registered destinations
3. Check FMC/call through functions, check users and dialling privileges
4. Check entries in the IP release list

When using Auerswald IP system telephones with integrated voicemail:

1. Check the access data, change the password
2. Check the destinations for call deflections
3. Check the voicemail boxes, check activation of remote control and change PINs
