3. Using MS Windows Messenger with a custom SIP Server

Although MS provides its own SIP server, known as MS Live Communications Server, this article is based on experiences during the usage of MS Windows Messengers with SIP Express Router (SER).

In your real configuration, you have to replace the addresses presented in this document with the proper values for your SIP service. So, in the next examples we will use “sip-server.net” as the address of the SIP server (registrar and proxy), “[email protected]” as the SIP address of local user and “[email protected]” as the SIP address of the remote user.
