I am working with customer to deploy Cisco Collaboration Edge Solution. I have attached a solution diagram with the case. The solution includes:
1. Cluster of CUCM Servers 2. Cluster of IM & Presence Servers 3. Cluster of Expressway C Servers 4. Cluster of Expressway E Servers
As you see in the diagram the servers are configured with internal domain "net.lab.com". The public domain is "lab.com" which is routable on the internet.
Following are the questions about the solution:
1. Do we need to create separate clusters for Expressway C & E? 2. Do we need to create separate cluster names for Expressway for C & E? 3. What DNS SRV records are required for Expressway C on internal and external DNS server? 4. What DNS SRV records are required for Expressway E on internal and external DNS server? 5. What DNS SRV records are required for Jabber Users on internal and external DNS server? 6. Can we use "lab.com" as our SIP domain? Is it required for in this solution? 7. Is it required to configure Expressway E with public domain name "lab.com"?
Please feel free to provide additional information.
