I am testing Windows Messenger 5.l and it works fine except when I connect other users that are on the SER box, it does not show them as on-line. It displays them as off-line. I am able to make sip calls through the SER Box. Everything works fine in that aspect. I want to use the Windows Messenger as a communication aspect to be able to send instant messages to the users. Please let me know if this possible with this Windows Messenger? Thanks.
