A route is a set of external numbers within one outbound group, all using the same peer, and sharing a common prefix. When an outbound call is made, the route with the longest prefix that matches the called number is used. The outbound group for the route is used to bill the call, and the call is delivered to the peer for the route.

For example, a system could have "UK" and "UK land lines" outbound groups, with "UK" having route 0044 and "UK land lines" having routes 00441 and 00442. If a call is made to '00441234567890', the route that is used is 00441, as it is the longest matching, and the group used for billing is thus "UK land lines".

To add a new outbound group

1. Log in to the Enswitch web interface.
2. If you haven't already done so, make an outbound group and a peer for the route.
3. Go to System » Routes.
4. Click the "Add a new route" button.
5. Enter the following:
   • The prefix for the route.
   • Optionally a description.
   • The outbound group to use for billing.
   • The peer to send calls to. If you select "Least cost", the system will automatically choose the cheapest peer with a price set for the appropriate outbound group.
6. Click the "Save" button.
