Description:The DTMF packets sent by app_senddtmf via sip when in RFC2833 mode are not properly decoded by the receiving end, and no DTMF is received by the other side.  This has been discovered during an inter-op test between asterisk and a Pactolus SIP server.


Attached are two packet dumps - one from asterisk sending the RTP Event packets and one from a Telica sending the RTP event packets.  The RTP event packets from the Telica are properly decoded by a Pactolus server.  However, the packets sent by Asterisk are not properly decoded by the Pactolus server.  Looking at the packet dumps, this appears to be an issue with ether the "Duration" field of the RTP Event packet, or perhaps with the number of packets sent before "End event" is set to true.

This isn't a major bug.
