Sounds like you have "dtmf_avt_payload: 100" in your SIPDefault.cnf or
SIPmacaddress.cnf file...

Seems the verion of the 7960 I use wants to use rtp protocol 100
for DTMF tones and it is not defined within rtp.c.

I had submitted a patch a long time ago, but it appears rtp.c went through
a major rewrite and this change was lost.

So here is a patch to add it back should you be inclined.
