I'm not sure if this is what you are looking for, but if you are trying to limit the length of the calls there is a system wide service parameter:

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

Thank You for Your answer. But that is not what I means.

If we set timer in Service Paramaeter, it will impact all device Voice Gateway.

I just wonder 1 PRI with Disconnected Timer Force.

Is there any idea? please help me

You would need to use H323 and write down a customized TCL script to do this, there is no built-in mechanism for this.

Also the timer won't only affect the whole VGW, it will affect EVERY SINGLE CALL made on CUCM.

Thank You Javalenc

what do You mean "it will affect EVERY SINGLE CALL made on CUCM" ?

is it mean all ipphones call trhough this VG will get disconnected timer treatment ?

if in VG, I have 2 port PRI. I want only set Disconnected Timer force on port 0/3/0 (not on port 0/3/1), is it possible ?

I don't have an experience create TCL sripct. is it hard to create this Script ?

I miss-understand, I think there is have a IOS command to set Timer for Force Disconnected call

The comment was on the CUCM parameter, not on TCL

Call time limiting for VOIP calls

From above

I know you can do that with TCL scripts running on h323 GW.  But I don't know if that can be done in the CCM.

Here is the link to TCL scripting in case this is what you are looking for.

Search NetPro to find all the previous post on this:

time + limit + calls

If you are interested in aquiring (paid for) such a script, please contact me at the address present in my profile.

Please note, TCL/IVR scripts can work only in H.323 or SIP mode, not MGCP.
