After your customer has configured Direct Routing, set up the trunk profile with information from the customer’s main SIP trunking account.
Specifics
For each Trunk profile you create, you need a unique domain name associated with the IP address of the SIP node.
To define a set of domain names, list them in the DispatchingNode.sip_domains field on the Configuration server web interface.

Contact PortaOne support team if you need assistance.
