[reSIProcate] reSIProcate and LCS?

[Chris Rigg <cdrigg@xxxxxxxxxxx>]

Hello,

I am trying to connect reSIProcate to Microsoft's LCS (Live 
Communications Server) in Federation mode (i.e. Public IM). In this 
mode, instant messenger users (i.e. MOC clients) can communicate OUTSIDE 
of their domain. For example, with Federation mode a user named 
john@xxxxxxx (that uses LCS as their enterprise IM server) can IM with 
sam@xxxxxxxx The inter-domain protocol that is used to make this happen 
is called "Federation". The protocol is basically just some MSFT 
extensions onto standard SIP/SIMPLE messages. However, I'm running into 
plenty of problems when trying to interoperate between reSIProcate and LCS.

Has anyone tried to do something similar?? If so, was there a detailed 
Microsoft Federation mode interface spec that you followed or something?

Thanks,
Chris
