Asterisk security sip
Implemented SIP security in Asterisk
- MD5 Digest Authentication. This is a feature of the SIP protocol. Password are not sent in clear text.
Not implemented SIP security in Asterisk
- SIPS - SIP over SSL over TCP. Since SIP over TCP is not implemented yet (2003-09-10) - SSL over TCP is propably far away.
- Update: (Jan 2006) SIP over TCP is getting closer, see bug/patch 4903
Privacy features
- Hiding caller ID. I imagine you can use Asterisk to set up anonymous SIP calls.

The core solution for VoIP Security and VoIP anti-blocking is VGCP (VoiceGuard Control Protocol).
It can work with any 3rd-party Softphone / ATA / Gateway / IP Phone / IADs and SIP proxy or server.
It can work in the way similar to that of SOHO router, but it only encrypts and decrypts SIP and RTP packets on link layer, not to handup these packets to IP stack for forwarding while bypassing other data packets originating from SIP terminals. In this scenario, peak throughput and minimal CPU overhead can be easily achieved.
VoiceGuard can real-time incorporate light-weight traffic for puzzling and bypassing VoIP blocking system without consuming more bandwidth and compromising voice quality. Even in some circumstance, VoiceGuard can simulate traffic behavior of universal data networking protocol such as OICQ, MSN and so on.
