[reSIProcate] reSIProcate and LCS?

[Sandeep Sharma]

I tried to make resip and LCS work together a while back. without much
success. TLS is required. I have heard LCS 2005 SP1 has fixed a bunch of
federation related bugs but have not tried with it myself.

One thing I do know is that page-mode instant messaging is not
supported. MESSAGEs need to be sent inside an INVITE session.

Chris, it might be interesting to exchange notes since I am going to try
testing against LCS 2005 SP1 soon.

Thanks
Sandeep
