"MSN Messenger" and Asterisk question

I’ve been researching around on the web for a work up or config how-to on getting MSN Messenger, NOT Windows Messenger, to work via Asterisk. I know its possible to config a MSN Messenger client to run thru a SIP server, just don’t know how to config Asterisk to allow connections.

If anybody has any links or any info regarding said issue, please post here as it will be appreciated.

I don’t think the new MSN support the SIP, but old one does.
