What kind of phones were these taken from? Spectralink phones can be used with a variety of PBX systems so you may not be looking at traffic that is pure SiP. For instance, Spectralink makes wireless telephones that can interface with the Mitel PBX, which uses proprietary encryption on its voice traffic. ________________________________ From: pauldotcom-bounces at mail.pauldotcom.com [mailto:pauldotcom-bounces at mail.pauldotcom.com] On Behalf Of Larry McDonald Sent: Monday, October 26, 2009 2:28 PM To: PaulDotCom Security Weekly Mailing List Subject: Re: [Pauldotcom] Decoding Spectralink to Audio? 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.

The network was WEP encrypted, which I was able to decrypt in Wireshark, but the filters for the various types of VoIP aren't picking up Spectralink. I've done some googleing and haven't found anything yet...
