[Serusers] Instant Messaging cannot work with Windows Messenger 5.0

[KokMeng Loh]

Hi,

Didn't get a response to my last mail, so I'd like to try a different 
question. Has anyone gotten Windows Messenger 5.0 (or for that matter, 
any version will do) working using SIP? Which SIP server did you use? Do 
you have any traces which I can reference?

Regards,
KokMeng Loh
