SIP proxy

[Magnus Ahltorp]

I just wrote a SIP proxy in Erlang. It is available under a BSD-type
license, and is a prototype at the moment, but I hope to productify it
in a few days.

Time for learning Erlang and and writing it: 1 week.

Features at the moment:

* Redirect

* Proxy

* Option to make all signalling messages go through the proxy (with
  Record-route)

* Voicemail

* Remote administration (custom r-e-p-l on other node)

* Web interface

* Dynamic registration of phones

* MD5 digest auth of phone registrations and outgoing calls

* Static forwarding of calls
