Trailhead sends a Route Request message to the Web PG, which, in turn sends the Route Request message to the ICM Central Controller. Using the Route Request message, the Web PG (the routing client) asks the ICM for a destination for the call.
The Route Request message sent to the Web PG can contain the following ICM variables. (Each of the 10 Call Variables listed below can have up to 40 characters.)
