You want to set up calls from endpoints registered to Cisco Unified Communications Manager to video endpoints registered in VCS. How do you set up the configuration in Cisco Unified CM?
A. Create a route pattern and assign the SIP trunk that points to the VCS.
B. Create a SIP route pattern as IP address routing with the VCS domain, and associate the SIP route pattern to the correspondent SIP trunk that points to the VCS.
C. Create a SIP route pattern as domain, and associate the SIP route pattern to the correspondent SIP trunk that points to the VCS.
D. Set up a SIP trunk.
I also think the correct answer is C
I was think “A” correct if:
Create a route pattern and SIP trunk that points to the VCS.
I think “C” is correct

These two options are valid:
1. add a SIP route pattern in order to send calls with “suffix” as Example.domain to the VCS Control / Expressway-C trunk.
2. add a route pattern to send calls with pattern “xxx” to the VCS Control / Expressway-C trunk.
I also believe that the most correct is the answer C.
