We are having an issue with our lync system. We have integrated with Exchange 2010 UM but it will not transfer the call to the dialled extension or said user. Its just goes quiet and does nothing. There are no wrrors that i can find in the event viewers.
Another issue is we want extensions for all users which we can do but also some users need DDI numbers. How can we setup the user to have a DDI for external callers and an extension number for internal callers.
I have tried numerous things to fix both problems but im at abit of a dead end now.
