Mon Nov 1 10:17:51 EDT 2010

It's what the Microsoft reps told us during our discussion on Lync / CUCM
integration.

Yes it was a session for an intro to Lync.maybe I will review the recorded
session again if you got the information from  a solid source "maybe I
miss-understand something in the session".

What version are you talking about? 2010 / Lync can use G.711 without a
mediation server.

This is new to me really.I had the below statement from a MS consultant
"their only supported codec is RT-Audio and you need a mediation server
whenever you need to integrate OCS with the outside world!!!"

The MOC clients can communicate using G.711 without the need of a mediation
server but you have to configure them to do so.

I think you will need a MS mediation server "as per Microsoft design" in
order to convert their codec "RT-Audio" to a codec that Cisco infrastructure
can understand.

Hi,

We're in the middle of a Microsoft OCS POC integrated with UCM 8.0. I can
make internal and external calls from OCS using UCM as my gateway, but calls
are dropped as soon as they're answered. Has anyone out there come across a
similar problem.

Kind regards,

Sechaba Mokoena
