This question reminds me of this clip from "Good Morning, Vietnam".

The abreviations CCT MSC and IVR are perhaps not known to all :-)

DTMF can be sent in the RTP packets or out of band or as RTP Events I beleve. What are you expecting to see? and where is your trace Point? what equipment is supposed to send the DTMF?

Can you share the packet capture? the DTMF could be either inband and in this case it would be just represent as audio (RTP).

one out-band option could be as part of the SIP and you will be able to find it by using this display filter sip.Method == INFO
