In the Cisco CallManager 4.x, which is connected to Avaya 8300 Media Gateway Server, normal calls works fine but the call drops when three party confrence is initiated

Core Issue

In the Cisco CallManager 4.x environment, which is integrated with Avaya 8300, normal calls works fine and when a confrence call is initiated the call drops immediately.  Also media gateway server shows the Temporary Failure error message.


This issue occurs when Media Termination Point (MTP) option in the H323 GW config in CCMAdmin page is not checked. In order to resolve this issue, check the MTP in order to have the supplementary services.

Refer to Media Termination Point Configuration for more information about the MTP.
