Providers and PBXs
The SIP port is a port on the local system that is used as a starting point for
the SIP transfer.
Notes:
The SIP port must be different for each provider/PBX.
You will find an overview of the PBX ports in the Configuration Manager
of the PBX under
Overwievs > Ports
.
Enter SIP port.
SIP session timer
The SIP session timer regularly verifies if the call connection still exists.
(The telephone/PBX cannot recognize if the provider interrupts the call
connection).
SIP session timer interval (min.) (5...6)
Indicates after how many minutes the SIP session timer should check the
call connection.
Note:
The enabling of the SIP session timer can cause increased breaks
in conversations after the set interval, if a provider has not implemented
the renewal of the session cleanly. In this case, you should disable the
SIP session timer.
