Hello Richard/ All,

I am a novice to ethereal, I was wondering how you go about saving the payload of a VoIP (RTP) ethereal capture.
I have a Avaya IP403 office plus 4602 IP phone on test, 
Is it possible? plus then to play the conversation. 

If you know a good source of VoIP info include the packet setup sequence it would help

Thanks
Andy

Don't know VoIP, but have you tried saving each channel seperately?
