Cisco VG204 and Intercom

Unanswered Question
Sep 9th, 2010

Hi there,

The customer got Siedle Intercom and connected to the CUCM 7.1 via Cisco VG204 (MGCP). The following is the (call)flow:

Custeromer > Siedle Intercom > VG204 > CUCM > Reception Telephone

The Reception press the # and the door is open. But the line remains open after the door has been opened and the Intercom has hanged up the line. Under Voice-ports I tried to play with "timeouts call-disconnect" and "timeouts wait-release" but it didn't work.

Any suggestion will be highly appreciated.

Thanks.

I have this problem too.

Hello,

Is it  possible that the intercom system is staying offhook ?

Have u tried hooking up an analog phone in place of intercom

system to see if it behaves the same ?

We can investigate further if u can provide following for one failed call:

deb vpm sig

deb mgcp pack | err

Also capture following before and after the call:

show voice call summ

sh voice port summ

sh mgcp connect

Please include sh run and specify the port intercom is connected to.

Curious if the receptionist's phone is an ip phone or an analog phone

(hanging of the same VG?)

Do you know if  hitting # xlates to a hookflash on the line ?

Thx.

DK
