Expressway E server certificate for B2B

[mzee.sidd]

Is it Mandatory to have Expressway E server certificate signed by Public CA for B2B calling. If yes, Can anyone share the Cisco documentation for the same.

Hi 

If B2B calls are intended with a trusted partner or Customer that accept an untrusted certificate to communicate and/or allow non-encrypted calls, so the certificate is not required but in general, in a public environment, you usually collaborate with different business entities or customers so a public trusted certificate is mandatory.

That would also allow you to join public Video Conference Services with just configuring Search Rules and Call Policies in your Expressway Cluster.

Here is a reference doc that explains why and how to deploy certificates on a Expressway Cluster
