Hi
We have noticed that DTMF is not working with UCCX,
Call flow ->
PSTN (SIP)-> CUBE - (SIP)-> CUCM - > UCCX
UCCX DTMF is working with IP Phones which are registered with CUCM, But not working with PSTN incoming calls, also we have Unity Connection, for this DTMF is working with PSTN incoming calls,
Please help to troubleshoot this issue,
Rgds
