expressway

[Toss Leey]

I have questions related to expressway

-the exp-e and exp-x should be match on numbers like if have 3 exp-e should have 3 exp-c?

-the one exp-e how many concurrent softphones will register to CM and make calls

-if have 4 exp-e is that mean i need 4 public IP, what if i can't provide 4 public IP; can i make 1 or 2 public IP with 4 exp-e nodes?

Capacity depends on OVA size and VM count in the cluster (scale doesn’t increase linearly). See the Capacity and Sizing chapter of the admin guide. Each Exp-E VM requires a unique public IP; PAT isn’t supported.

If you have 4 Expressway-C servers, you will need 4 Expressway-E servers and 4 public IP addresses. For a small OVA, the number of calls supported and device registrations over MRA do not increase with additional peers in the cluster. However, medium and large OVA clusters will experience an increase in call capacity and device registrations. Please refer to the admin guide for the specific Expressway version you are using, as shared by @Jonathan Schulenberg .
