Greetings,
I seem to be having some trouble with the pa module on SER 0.10.99-dev0
running on Fedora 3.
I can REGISTER fine, and issuing a SUBSCRIBE results in a 200 OK response
(and NOTIFYs being generated by the server).
However, both the 200 OK response to the SUBSCRIBE and the NOTIFY messages
are all missing a Contact header field.
Here's the messages:

Message body
======================================================
I've been looking at all the documentation I can find, and I can't seem to
find out why these are being omitted.
Is there something wrong w/my configuration? (see below) Any suggestions
why this might be ocurring?
