3.4.9.2 Response Timer
The Call trans timer is started whenever the phone sends a new INVITE message to the SIP
server.
If the call transaction timer expires before the phone gets a response from the SIP server, the
phone assumes that the server had died and then attempts to contact the backup server, if con-
figured. If there is no backup server configured, the phone just tidies up internally.
The data is given in milliseconds. The default value is 32 000.
