When the failure occurs, the topology is set up as shown
The ICM route point is associated with an ICM script which does a
Translation Route to a VRU node to trigger a script on the IP IVR, as shown in
below. This Translation Route VRU node
When testing this specific ICM script through CallTracer, it completes
correctly. However, when the incoming call hits the route point in the
production environment, it fails with the following sequence:
Experiencing a short bit of silence.
A fast busy.
This is a configuration issue. View the rtr log file on the Router
utility, the following message appears:
15:20:51 ra-rtr Trace: TranRouteToVRU failed. Unable to map route 5009 to a network VRU
Verify the specific route, it is associated with a specific IP IVR.
Check the configuration in PG Explorer, the Network VRU name
is set to NONE instead of the name of this specific IP IVR
under Advanced, as shown below.
Select the right Network VRU name resolves this issue.
