H.323 interface configuration task list 438
SmartWare Software Configuration Guide 38 • H.323 interface configuration
Note The call-signaling port specified here has no effect, if a gatekeeper is used. In
that case the gatekeeper will provide the portnumber to use for establishing
the call signaling connection
Procedure: To configure an alternate destination TCP call-signaling port
Mode: Interface H.323
Example: Specifying an alternate destination call-signaling port
The following example shows how to set the destination call-signaling port number for the H.323 interface
MyH323If to 2300.
node>enable
node#configure
node(cfg)#context cs
node(ctx-cs)[switch]#interface h323 MyH323If
node(if-h323)[MyH323If]#remoteport 2300
Configuring status inquiry settings (optional)
Normally, the H.323 gateway will send out status inquiries every minute on each connected H.323 call.
According to the H.323 standard, the remote entity must respond to these status inquiries, which allows the
H.323 gateway to detect, if the call on the remote H.323 entity is still alive. If no response is received after
another minute, the call will be dropped.
Unfortunately, there are H.323 entities, which do no respond to these status inquiries. This causes every call to
be dropped after being connected for two minutes using the default setting.
As a workaround for these non-compliant implementations, it is possible to disable the status inquiry check-
ing.
It is also possible to change the default status inquiry interval of 60 seconds to a different value, if required.
Procedure: To disable status inquiries
Mode: Interface H.323
Example: Disable status inquiries
The following example shows how to disable status inquiries for calls handled by the H.323 interface
MyH323If.
node>enable
node#configure
Step Command Purpose
1
node(if-h323)[if-name]# remoteport port Specifies the TCP port to which the call-signal-
ing connection should be established.
Step Command Purpose
