Is it possible to make a call from the CISCO IP Phone 9971 to CISCO Telepresence CTS-MX200 (or from CTS-MX200 to 9971)?
Is there a configuration to be done?
Yes. Two scenarios that I know of.
1. Both devices registered to Callmanager.
2. Phone registered to Callmanager, CTS-MX200 registered to VCS. SIP trunk configured between VCS and Callmanager.
