Hi
We are wondering if anyone has used the new presence module with Snom
phones because it looks like it just doesn't work with the subscribe
types that snom use.
Basically snom uses Event: dialog in the headers which the module
doesn't support.
Here is the subscribe after I hacked it to allow Event: dialog
U 2006/11/15 14:22:04.699050 193.84.87.60:5082 -> 193.111.201.74:5060

.
Then openser sends out this notify
U 2006/11/15 14:22:04.733404 193.111.201.74:5060 -> 193.84.87.60:5082

.
Which is most significantly the wrong content type for snoms (as the
subscribe said, they want application/dialog-info+xml) and also doesn't
have a message body on the notify - so the snom tells openser where to
go:
U 2006/11/15 14:22:04.841722 193.84.87.60:5082 -> 193.111.201.74:5060

Thoughts welcome!
