Hello everyone. First, I have a few information to trade. I set up our emails few years ago and did not have any problems at all. Every person in our company has no timetable for its creation.

It was installed through a browser and then it "exchangeserverip/exchange"

I was attempting to assimilate Office Communications Server (OCS) 2007 to a current SIP (Session Initiation Protocol) infrastructure through its own proxy. Configuring correctly the Routing and Host Authorization options, I was able to call using the OCS 2007 client to SIP clients. But the problem is I was unable to do the reverse way. I cannot make a call from my SIP client to OCS 2007 client. What is your solution to this?
