[SIPForum-discussion] Problem DTMF

[Vinicio Callejas]

I have a problem on an interconnection DTMF with a client which sends
RFC-2833 (telephone-event) and our team will respond with a 183-progress
session and 200OK message with no (telephone-event).
THEREFORE, it is Assumed That You are INBAND dtmf. This would not be
reliable with G729 codec.

As far as i see  has RFC2833 but for some
reason customer says did not receive the telephone-event on the 183 session
progress or 200ok messages sent by.


Could someone explain how to solve this problem.

Very thanks,
Vinicio
