SIPtap (A Proof of Concept Tool), Taps into SIP Based VoIP Calls Records Them.

I have mentioned security issues involving VoIP IP Telephony as close as few weeks ago as well as two years ago!
Today I hear and see another side of it. Proof of concept of wire tapping and recording of VoIP conversations. The Proof of concept tool called SIPtap is able to monitor multiple Voice-over-IP calls in SIP, listen and record them. for remote inspection as .wav files. The tool could be deployed on client side or in the middle man domain, ISP.
The creator of Proof of concept tool
is Peter Cox, who co-founded firewall vendor BorderWare. He since left BoderWare to start his own VoIP company, so far only known as (The last time I checked, the domain is still registered under Borderware.

Asterisk SIP Registration Vulnetabilities and Limitations(White Papaer)
