Expressway communication between internal user and external

Hello,

I have CUCM, Expressway C, E, Jabber and MRA phone services. Planning to add Webex Hybrid Calendar services and Webex Edge Solution in future. I would like to know, how expressway E is using for signaling and media communication between internal and external users. Expressway E is in Public DMZ.

 

Scenario 1:  One user is internal and 2nd user is external (one to one)

Scenario 2: 3 users are internal and 5 users are external (Many to many)

Scenario 3:  1 user internal and 5 users external

Scenario 4: 5 users internal and 1 user external

 

Does expressway E using for all these communication?

Is there any differences if Expressway is in Public Internet?

Do the work and read up on the subject at hand, not only will you end up learning something along the way, you will also likely become a better engineer on the other end of this. At least a more knowledgeable one.

There is no such thing as a free lunch as the saying goes.
