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.
