This article explains how to route calls to a SIP Trunk from within a Domain by creating a routing user that forwards to the SIP Trunk extension. The routing configuration detailed below also allows for failover options for users. For example, if routing to one user or a SIP Trunk and you select ‘Forward when busy’ or ‘Forward when unavailable,’ then the call can be routed to a SIP Trunk instead. Before getting started, please be sure a SIP Trunk is already created for the SIP Domain you are using. To create the SIP Trunk Routing User:Starting from your PBX Portal, navigate to the 'Users' tab. Select 'Add User' on the right-hand side. Supply the following User information (If not mentioned, you may leave other fields blank). First Name: SIP Trunk Last Name: Routing Extension: Enter a 10-digit extension you wish to use for routing to the SIP Trunk. Click 'Add User' at the bottom right side of the menu. Navigate back to the 'Users' tab and locate the user you just created, named "SIP Trunk Routing," and edit the user's Answering Rules by clicking the "Pencil" edit icon to the right of the default answering rule.While editing the user, configure the Answering Rules to Always forward to the SIP Trunk (User SIP Trunk or Phone SIP Trunk).
