Hi,
I am running Windows Messenger Clients V 5.1 (SIP Communications Service
enabled) on etiher side of my SIP proxy. They can do presence, voice
calls, whiteboard, application sharing, BUT cannot do Instant Messaging.
I tried with few other SIP Proxies, but they too cannot do IM.
When I analyzed the network traffic, I found that the sender sends a SIP
INVITE and the receiver sends a SIP OK in reply. But immediately,
afterwards the receiver sends a SIP BYE message to terminate the dialog.
Thus, the SIP MESSAGE message from the sender couldnt reach beyond the
proxy as there was no corresponding active dialog.
I have no security issues as I have turned off EnableHighSecurity
option. Also there are not NAT issues, as both the clients sit in the
same network.
I observed this issue with WM 5.0 also but not with WM 4.7 as WM 4.7
doesnt send a SIP INVITE to initiate the dialog.
Please help.
