Select Route Profile

Route Profile(s) are used to handle routing for DIDs. Here you will want to create a new profile unless you have already created one previously that you want to associate this flow with.

Route Profile Route(s) are used to determine where the DID should be routed to. Each Route Profile Route can be assigned a priority, destination type, and destination. The Route Profile Route is used to determine which route is selected when an incoming call is handled
