Call duration limitation

[qazzaq201]

Hi experts,

We faced a problem that some user don't hang up the call so there will have some ports be always occupied...

Is there any possibility to limit call duration on ISR 4431 or 3945?

Like if call duration exceed 1 hour, ISR will initiatively disconnect the call..

thanks in advance

Nothing native on the IOS. You can use a TCL script. Open up a TAC case and see if they can provide you one. It is a generic template script that should work fine but is not TAC supported. Alternatively you can post at Cisco Developer Forums. Someone there should be able to help you.

Hi

Service parameter configuration can help you achieving this. But its a global configuration and affects all calls, both internal and external.

Maximum Call Duration Timer:	This parameter specifies the minutes that a call can remain active before Cisco CallManager clears it. A value of zero disables the timer.
	This is a required field.
	Default:  720
	Minimum:  0
	Maximum:  35791
	Unit: min

You need to write down a TCL script. Please check out a similar post
