Hi, we're currently trying to do something like that here at Saarland University. We will give each VoIP-User his own extension that will be routed to Astersik over an E1 (We will use extensions like 69XXX for that). I think this routing can be done easily in the PBX. We will also set up a SIP Express Router and give an account to every student here. Students will eventually also get their own extension that can be reached from everywhere (something like 70XXXXX). The students will be able to call every phone here on campus over the Asterisk-System (including other students of course :) ). This is mainly to prove that a simple cheap VoIP system can handle that traffic. In a second step we will try to replace the existing PBX with Asterisk and SIP phones or channel banks. This will of course take some time. :) Another goal of the project is to route calls to other universities over IP if they support it. You can find some information about our project on our Website (see below). -- Maik Schmitt http://graphics.cs.uni-sb.de/VoIP
