[Spce-user] RFC2833 events logging

[John Murray]

Tim, Andreas,

Thanks for that. I did use tcpdump and wireshark in the end.

Regards

John

John,

I have worked with several systems over the years that that will log RTP
Events to log files or the console.  I have found that the easier way to
troubleshoot DTMF events is to make a packet capture with tcpdump, then open
that file in Wireshark to dissect the calls.  The call ladders and protocol
dissection tools that Wireshark has make it much easier to analyze the call
flow and confirm the DTMF events are working as expected.

If you aren't familiar with capturing packets with tcpdump, I have found
this cheat sheet to be quite useful in addition to the man page:
http://media.packetlife.net/media/library/12/tcpdump.pdf (Note the -s and -w
options)
