[Serusers] WM 5.0 & iptel: presence

Hi, I've an iptel server running from CVS (stable), and want it to work with Windows Messenger if possible. Presence seems to be erratic at best, For instance I can see the current users with: serctl showdb but the presence in WM fi often wrong. Questions: - Does presences with WM work, if no are there workarounds/fixes? - Are there any other issues I need to know about WM? I want to use it in a small test pilot for IM, presence, Peer to peer audio calls, and pstn calls via a cisco gateway. - is there a searchable archive of SER mailing list? This is surely a FAQ, but don't flame me, I didn't see a link on http://lists.iptel.org/mailman/listinfo/serusers :-) Thanks in advance, Sean Boran
