Perhaps, I am missing something but thats what I see sjphone and other voip clients doing. 3 end of event packets are sent irrespective of the next dtmf digit in the queue. The remote end client to which we are connecting using pjsip recommends using 3 end of event packets. I think you're right. Although the text in RFC 2833 somehow implies that retransmissions should only be done when there's no new event in the queue, I found the clarification in RFC 4733, which obsoletes RFC 2833: 2.5.1.4. Retransmission of Final Packet The final packet for each event and for each segment SHOULD be sent a total of three times at the interval used by the source for updates. Could you send me the diff again? cheers, -benny > Madhuri >
