Once you get the raw file out of the pcap do this: sox -t ul -r 8000 -c 1 file.raw file.wav That's assuming it's ulaw. Change "ul" to "al" if it's Alaw. If it's some other codec then you'll need to figure out how to convert the raw to wav. (That's where anthm's improvement of fs_encode is really handy.) -MC On Wed, Mar 6, 2013 at 1:16 PM, Avi Marcus <avi@avimarcus.net> wrote:
Paul, yes, pcapsipdump is great. But now I want a .wav file out of that call, and wireshark crashes on certain files when trying to decode it... hence the question of other ways to extract it.

I am presuming that the pcap contains multiple "streams", so why not use a display filter to isolate and save each stream you are interested in,
I believe that pcapsipdump can do this as well - take a pcap and create per-call pcaps from it (SIP+RTP).
