Enable the session timer (optional)

The gateway implements the SIP session timer feature, which is currently only defined in SIP draft standards.
The session timer feature allows a gateway to check periodically during a call, if the remote gateway is still alive
and if the call is still connected on the remote gateway. You can enable this feature using the command shown
below. If the session timer feature detects that the call is no longer connected on the remote side, it will also
drop the call locally.
Mode: Gateway SIP/service
Step
1
node (svc-sip)[service]#session-timer seconds
Example: Enabling the session timer feature
The following example shows how to enable the session timer feature, with a refresh period of 1200 seconds.
node(cfg)#gateway sip sip
node(gw-sip)[sip]#service default
node(svc-sip)[service]#session-timer 1200
Advanced configuration options (optional)

Changing the listening port for inbound call-signaling

The default UDP/TCP listening port for inbound call-signaling connections is per default 5060 as defined in
the SIP standard. The following procedure describes how to change the port number.
Mode: Gateway SIP
Step
1
node (gw-sip)[hsip]#call-signaling-port port
Example: Defining an alternate call-signaling port
The following example shows how to define an alternate call-signaling port on an already defined SIP Gateway.
node(cfg)#gateway sip sip
node(gw-sip)[sip]#call-signaling-port 5061
Configuring the traffic class for SIP signaling
The traffic class for SIP signaling is configurable. The configured traffic class is used as additional routing crite-
rion in the IP routing table.
Mode: Gateway SIP
