Re: [reSIProcate] reSIProcate and LCS?
Hi Sandeep,
I just responded to Scott with some info that may be useful to you. I
would love to compare notes with you. I'll be using the resip stack
quite extensively over the course of the next few months to try to
interoperate with LCS 2005 SP1 (which is what I have installed
currently). I'll likely be writing several programs similar to "limpc"
that will generate INVITEs, SUBSCRIBEs, NOTIFYs and MESSAGEs (though, as
you pointed out, 2005 SP1 only supports session mode -- but it does
support receipt of MESSAGEs w/in an already established session).
Ideally, I would get my hands on a detailed interface spec that would
make writing code to interoperate much easier on myself. I suspect such
an interface exists since MSFT claims they interoperate with AOL and
Yahoo in Federation mode -- obviously those 2 companies had something to
work from.

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

Apparently to use "Federation Mode" you must use the TLS transport. As
far as I know - no one has tried this with resip yet. Although it is on
my list of things to try out. : )
On the other hand - I have used resip to communicate with LCS by setting
up the resip endpoint as a trusted node. Note: LCS does not support
UDP - so you must use a TCP transport. Don't expect to be able to
register with LCS though - since you need to implement those Microsoft
extensions that you mentioned (ie. Kerberos/NTLM Authentication instead
of Digest).

Subject: [reSIProcate] reSIProcate and LCS?
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
