outgoing calls to PSTN, per trunk. This timer is used between
the time that an ISDN Setup message is sent to the Tel side
(IP-to-Tel call establishment) and a Connect message is
received. If Alerting is received, the timer is restarted.
The range is 1 to 600. The default is 180.

by the PBX/PSTN or by the device, per trunk.
