Hello,

We have been trying SER with MSN clients for some time now. We are now using other clients, like Kphone 3.12 for internal chat and presence. The server has been working perfectly, without disruption and very work to set it up.

We want to start deploying new services on top of SER and, among one of the enablers, we have thought about a Presence Server. We have been trying the 2 possible ways to implement this: - Via a Presence server (using the pa module). - Using proxy mode (merely relaying SIP messages between clients, capturing relevant messages between clients).

The first option does not seem to work. Presence seems to appear "Away", no matter if the presentity is online or not. So we tried the 2nd option. We want to store the presence information of all the users on the server. To do that, we record-route SUBSCRIBEs and NOTIFYs, and that way we are able to get the presence information out of the message body in NOTIFYs. However, we have noticed that when an MSN Messenger client (acting as a presentity) notifies a watcher, it does so in a strange way that we believe is not standard (at least with v 4.6). The Request URI on the NOTIFY has the following format:

From the presentity:

NOTIFY sip:<presentity-id>@<server-ip> (MSN Messenger's behaviour)

While according to the SIMPLE specs should be:

From the presentity:

NOTIFY sip:<watcher-id>@<domain/server-ip> (Kphone's behaviour)

Is this correct according to the SIMPLE standards? Was it solved in later releases of MSN Messenger?

All this may be solved when the PA module becomes ready...

Regards,

Jaime
