Max Call Duration for Overhead PA calls

CCM 4.2 Sets = 7900

Does call manager have an option or setting to control the duration of a call.

We have a joker on site who is queuing up the PA amp via CCM phone then walking away, leaving the hanset off.

From the phone we dial a code <*555> that hits a route pattern that hits a router then a PA interface and then the PA amp.

we would like to make this call a max duration of 30 seconds. any ideas?

Many Thanks

Re: Max Call Duration for Overhead PA calls


What about using the following?

This command will make the port to remain connected for 30 seconds after no voice activity is detected by the voice port:

voice-port 1/0/1

timeouts teardown lmr 30

If it hopes please rate! :)

Re: Max Call Duration for Overhead PA calls

Thanks Teresa -

I figured if it could be done it would be done at the port level. But what if there is a lot off backround noise, this would count as voice thus activity?

Also this port a FXS on a 2600 router.

Thanks again
