We plan to have a centralized CCM cluster in one region with distributed Unity Server for Unified Messaging. For example two CCM's in New York and Unified messaging in Atalanta integrating within the same exchange site, etc. etc. My concern is the TSP registration over a WAN link with CallManger. Are there any issues????<br><br>Thanks<br><br>
As with any network application, you are going to have to provision enough bandwidth. Unity and the TSP are ignorant to the fact if CCM is on another subnet, in another campus building, or half way across the country.
From a design standpoint, it seems a little curious that every single direct and forwarded call to Unity will traverse the WAN. Seems kinda bandwidth expensive at first look.
Remember, Unity 2.4.6 can only support connecting to a single CallManager cluster.
The design is a little more complex than that. I was specifically trying to eliminate any problems with the TSP registering over a WAN link. I wanted the Exchange Messaging to take place on the same local network, however, CCM's will be in one central location...
