Hmm...if it's SIP telephone adapter...perhaps the telephone is fault,
try change to another telephone. Try using SIP INFO for sending DTMF
digits...it's more reliable. Let us know how you setup your endpoint and
what that you're using. You can try isolating the problem by using a SIP
ip-phone then an adapter to ensure the analog phone is not the cause of
the problem.
