asterisk users - May 2007 - IAX2 sniffer and player

Hi all,
I was wondering if there is any IAX2 sniffer and decoder. Wireshark
can decode and play RTP streams using G.711, and Cain & Abel decodes
and plays any kind of RTP stream. But I didn't find anyone that can
decode IAX2 streams.

Any programs??

Regards,
