question about hybrid deployment

[mr_cisco_cisco]

Say you want CUCM and CUC on prem and jabber in the cloud (ie webex messenger).  Do you need to have public IP's for CUCM and CUC for this to work?

Hi,

I believe if you are talking about hybrid setup then you are leveraging webex cloud and registering 

to CUCM on prem. In this case you would be deploying a Mobile and Remote Setup which 

would have Expressway-C and Expressway-E (which would be in the DMZ). Your jabber client 

would be talking to Expressway-E and therefore you would not need Public IP for CUCM.

Please rate and mark correct if helpful
