I would like to know if CME is able to route video calls to a Polycom device?
If so, which HW/IOS is the minimum requirement.
Thanks in advance!
There is a little more to it than just the dial-peers but overall in either of the two scenarios you list, CME has no interaction with the calls being made. YOu can just replace "CME" with "router/gateway" in those call flows. If you do want to call between a CME registered IP phone and video EP then you would need to enable video support within CME.
