Hi Rejean,
Sorry for the delay! I believe the elements Ryan referenced are more for the actual scheduling of meetings. I've run a test with the following XML CreateUser request and it was successful. Basically, you just need to enable telephony options for the user to be able to use for these meetings. The user doesn't have to have all telephony privileges, but in this case I enabled all available.
CreateUser:

To confirm that CMR was enabled, I called GetUser and this is the response:
