Decoding Spectralink to Audio?

[larrymcdonald at uhost.org (Larry McDonald)]

I have had some luck decoding VoIP with Cain and abel. Under the Sniffer tab
there is a sub-tab for VoIP, worked real nice for me converting network
capture for the sessions into wav files.

Here is some info from the manual:

How it works

The sniffer extracts RTP session parameters like RTP ports, caller/responder
IP addresses and dynamic codec types from SIP or MGCP session preceding the
data flow on RTP. Then it captures and decodes RTP audio streams encoded
with the following codecs: G711 uLaw, G771 aLaw, ADPCM, DVI4, LPC, GSM610,
Microsoft GSM, L16, G729, Speex, iLBC, G722.1, G723.1, G726-16, G726-24,
G726-32, G726-40, LPC-10, SIREN, LRWB-16khz. Once decoded the audio is saved
into mono or stereo WAV files on your hard disk.
