Hi Benny,

Hope it is useful.

irrespective of the next digit in the queue. 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
