3. Gigaset User account.

Without a Gigaset user account, the door intercom can be used to dial an internal number. Incoming and Outgoing calls are not possible.

Incoming calls to the door intercom are only possible when the door intercom is assigned to a user.

In the Gigaset T300/T500 Go to: Configuration - Users and create a new user, only to be used for the door intercom (user license)

4. Programming the Fasttel using DTMF.

Call the extension number of the Doorintercom.
The Fasttel will answer the call and will play DTMF tones.
Then you enter the programming access code: *1996*

But, the Gigaset T300/T500 already uses the code *1 for Call recording. This means when you press *1996*, directly after the *1, the PBX will start recording the call and you will not be able to enter the programming mode. You need to change the *1 code in the Gigaset T300/T500 to an other code.

How to change the *1 code.
  • Login the PBX using SSH.
  • Go to the directory /home/asterisk
  • Open the file features.conf and change the automon => *1 to *4
  • Restart the PBX services to activate your change

       blindxfer => NONEXISTINGEXTENSION1 ; Blind transfer, default is #
       ;disconnect => *0                  ; Disconnect
       automon => *4                      ; One Touch Record
       ;atxfer => *2                      ; Attended transfer

After this change, call recording is now done using the *4 code, the Fasttel can now be programmed using the *1996* code.
