DTMF-relay is enabled on the system. Please note the following :

The Public Interoperability System uses two Media Servers.
One is configured to support RFC 2833, while the other is not. The Application Server load
balances the connections to each of these servers. To make sure that the proper Media Server
is selected for this connection, verify via signaling that the SDP in the 200 OK from BroadWorks
includes the RFC 2833 payload type. Several call attempts can be required to connect to the
correct Media Server.

Hi skumar,

What you described is needed for testcase 33 "RFC 2833 DTMF Offered, In-band DTMF Negotiated".

However see the "Always_RFC2833.pcapng", DUT call Auto Attendant 10 times but the media server always has RFC2833 payload type. It seems there is no load balance effect. Please check

The DTMF Relay is now working
