I have a call manager 8.6 setup with 9951 IP Phone for Operator. 8 Analog lines are terminated with the voice gateway. All incoming calls from these lines coming to this operator phone. But when an incoming call comes it appears twice on the screen. When the operator selects the line he hears a lot of disturbance ans the caller also listens trhe same. I checked the Line using an analog phone and it appeared fine. Here is the voice-port configuration of the voice gateway.
! voice class custom-cptone UAE-KH dualtone disconnect frequency 400 cadence 400 350 !
I removed custom cptone configuration and checked and it is still the same. Can anyone please tell me if they have observed the same anywhere and any resolution ? I have implemented the same solution else where too and never had such an issue.
I would agree. Double check the physical connection.
When there is no call activity, just make an inbound call and issue "show voice port summ".
Check if you see two ports go off hook or just one. If you see two ports go off hook, then Chris is correct. If you see only one port go off hook, then check the actual physcial connection on the port, as a bad cable/bad L1 connection can cause port to go off hook and on hook multiple times for the same call, resulting in multiple calls from the same port.
