there are various options, you can just implement what works best and/or is
easiest.
I tried to package a set of tools for this but never got around to
completing it. And it was geared towards RobotFramework but the solutions
can adapt to other frameworks.
http://code.google.com/p/telcotools4robotframework/
you should look into pcapdiff, DetectDtmfFromFileLibrary, ToneDet,
Wireshark, and sox.
Basically, you capture/record the RTP stream with SIPP. Then with the
mentioned external tools, detect DTMF. How? Either by doing a diff of the
captured pcap RTP stream against known good version (if applicable) OR
convert the pcap capture into an audio file (can do via Wireshark), then
pass the audio file through some DTMF/tone detection tools (ToneDet,
DetectDtmfFromFileLibrary Python script, etc.).
Granted it would be nice if someone built & shared an all-in-on solution
where you just pass in pcap file and it spits out result, but we're not
there yet. My collection of tools is at least a first step towards that.
