ICM-to-ICM Gateway Call Flow
Pre-Routing
Figure 1-4 illustrates a call flow scenario for a call that is pre-routed from one
ICM to another.
Figure 1-4 Example Pre-Routing Call Flow
Step 1 The Service Provider network sends a route request to the Client ICM.
Step 2 The Client ICM receives the pre-route request and executes a routing script that
determines that the route request is to be handed to another ICM. The ICM
forwards the route request to the Server ICM.
Step 3 The Server ICM executes a script that selects a peripheral target for the call and
sends the corresponding label to the Client ICM.
Step 4 If the selected target is reached using a translation route, the Server ICM sends the
call context data to the selected peripheral, where it waits for the call to arrive. If
translation routing is not used, this step is skipped.
Step 5 The Client ICM forwards the destination label (that it received in Step 3) to the
network.
Step 6 The network connects the call to the selected destination on the Server ICM
ACD/Agent.
