On the System Manager web console, navigate to Elements Routing.
Create a new regular expression and routing policy to route the Inter-PS messages to either the local Avaya Aura® Session Border Controller in domain 1 or the remote Session Manager in domain 2. The routing policy must have either the local Avaya SBCE or the remote Session Manager as its destination SIP Entity.
Ensure that the regular expression contains a generic user and domain regular expression that identifies the users in domain 2. For example, .*@domain2\.com.
