Sounds good. In fact, DTMF key is 8 bit long - look at RFC 2833, chapter "3.5 Payload Format". I'm not sure why it is masked with 0x3FFF value in MpdPtAvt code. I think we may change this to 0xFF safely. So, there is plenty space available for other flags. Btw, signalled value is decoded in CpPeerCall::handleNotifyMessage(). -- Regards, Alexander Chemeris.
