Hi,

This will be a B2b calling. you will require RMS licenses on Expressway to accomplish this. Can you elaborate your scenario.

It sounds like you have MRA Expressways setup currently. You'll also need to deploy B2B expressways with the licensing mentioned already 'Rich Media Licensing'. Look through the b2b expressway deployment guide because you will also need to publish external DNS SRV records that will resolve your domain used in the URI to your B2B expressways. From there, the B2B expressways will have search rules that will point to the B2B C's>CUCM>Endpoint. Dont forget to open the ports on your firewall :)
