H.323 Plar to Unity AA problem, need help

Gateway: Cisco 2811 with newest IOS

CallManager: Ver 5.1

Unity Connection: Ver 1.2


All incoming calls would be going to Unity AA first. During business-hour calls will be transfered directly from the AA to the receptionist, if receptionist is not available, a Working-Hour-AA will handle the call. As soon as it hits 5:00PM then it will not go to the receptionist but will play the After-Hour-AA call handler. I have the connection plar working to the AA.

The configuration works well during business-hour.


After-Hour-AA will allow caller dial the extension, so I need the configuration:

dtmf-relay h245-alphanumeric

on the VoIP dial-peer.

When I tested to dail the main number(main number-> gateway-> plar 500[AA Number]), I hear the Unity prompt "I cannot recognize this invalid entry" instead of the After-Houre-AA, but the caller can still dial an extension and the call can be established successfully.

If I remove the configuration:

dtmf-relay h245-alphanumeric

from VoIP dial-peer, the call can be transfered to After-Hour-AA, but Unity cannot receive the extension caller dialed(it is true).

Is your Call Manager or your Unity server?
