Direct Expressway Edge to Expressway Edge communication

[douglasfir]

Hi,

I have a situation where I should connect two separate CUCM/IM&Presence clusters via two corresponding Expressway Edge servers, one at each cluster. Is it possible to do so and still keep all other Expressway functionalities like MRA and B2B?

(CUCM cluster)--(ExpC)--(ExpE)====(ExpE)--(ExpC)--(CUCM cluster)

I was thinking about creating additional search rules (or even separate DNS zone if needed) of direct communication between these two Expressways through DMZ. The reason I talk about DMZ for this communication is that these two clusters belong to two closely related (but different) companies.

Thanks!

Are you asking about an XMPP federation??

Hi Jaime,

Actually, I would also need voice and video going between these two Expressways too if possible...do you think it would be feasible?

Thanks, Dragan

Well, for XMPP federation you could certainly configure static routes, for voice and video, you mean basically do B2B?? If you manage to configure your DNS to provide the SRVs for your two companies with your own DNS, and anything else to delegate to a public DNS, it should work fine.
