It is a good idea: it does have benefits and competition from
FreeSWITCH is good for Asterisk.

The SIP proxy is really just an elaborate message routing mechanism.
It doesn't do any of the media handling, voicemail or anything else
really.  So it is easier to get started quickly, relatively more
secure (as there is less code), easier to support, etc

There are various ways to do this.  One thing I would like to offer is
similar to the webrtc.lumicall.org service - basically, every DD will
be able to tell their friends "go to webrtc.debian.org, type my user
ID and click 'call'".  The callers will not need to register, it will
be simple and anonymous, like a web form.

Other users could register through Lumicall or another service and due
to federation, they can then quickly and easily exchange calls with
@debian.org users

I've now updated the wiki page with more thorough infrastructure
requirements and submitted an RT ticket to the DSA team with IP
addressing requirements, that is the first step to enable everything
else.  Once the boxes, IPs and certificate details are confirmed by
DSA I will then make another ticket with details of package
installation and config files to use.
