MRA multi domain and multi cluster call manager deployment

[Bar1s]

Hi all,

Our customer have bunch of Call Manager cluster under different domains.

It is possible to use single peer Expressway C and E for external MRA clients? 

Since they have different domains there is no any problem inside. 

Desired topology is like that.

Thank you,

Baris.

Hello,

Yes this will work. But whether the external domain is same or different?

Also you need to add all domains in Expressway C and all domains should have proper SRV records created.

if different then you need to add all domains in exp-E cert's SAN also for all domains you should have _collab-edge SRV resolving to expressway E FQDN.

Thanks
