We establish a Collaboration Platform and ApplicationEndpoint on domainA and are able to then create UserEndpoints on domainA without issue. When we have a user in the same S4B topology whois sip domain is domainB we are always presented with an error establishing as that user. If we create a 2nd Collaboration Platform and ApplicationEndpoint giving it an address on of domainB it works, but then the same error occurs with a user on domainA.
All users are in the same AD and S4B topology. Is there any easy way to make UCMA work like this?
