It counts with me.

I wouldn't say this is sip.EDU "compliant" either. I don't think it 
would hurt
to reiterate what we mean by sip.EDU "compliant" but at the same time I 
don't
want to push away sites that are in the early stages of deploying SIP based
solutions.

When I think of sip.EDU I see two versions of the architecture. Version 
1 consists
of proxy(s) and gateway(s) that allow calls delivered to the proxy over 
IP to be forward
through the gateway to a PSTN endpoint on the campus of the proxy owner. The
forwarding happens if and only if the addressee is found in the proxy 
database.
Calls may originate from endpoints inside or outside of the campus in 
question.

Version 2 includes the ability to do "free form" PSTN dialing. That is 
to say the
called party number doesn't have to be an on campus extension. It can be 
whatever
range of telephone numbers the proxy owner wants to permit. Version 2 
also includes
the ability to do "free form" IP dialing. That is to say that called 
party number may be
an IP addressable device reachable via the proxy in question governed by 
the rules
of the proxy owner.

Using these definitions I consider UPenn to be a version 1 site.
