Webex calling DI Phons and gateway connectivity

[dijin]

Hi,

I would like to know how the ip phones at the on-prem register to CUCM in DI?.

Also, how do the local gateways connect to webex DI?

Thanks,

[dijin]

How does the enterprise phone register to cucm in the cloud? Do we need to update the TFTP server info with the cloud cucm FQDN in the dhcp pool?

Same way how does local gateway communicate to cucm?

please share any Cisco doc if you have to refer to the above scenarios.

You establish internal network connectivity with IPSec tunnels over the public internet or private transport via Equinix Fabric or Megaport. The preferred architecture document has a section on WxC-DI starting on page 62.

WxC-DI is normal CUCM hosted by Cisco. It’s the same endpoint and gateway architecture as the on-prem days.
