An explicit SendToVRU node only exits if the call is already at the correct VRU, as identified
in the usual ways (for example, the dialed number's customer Network VRU), instead of exiting
if the call is already at any VRU. If it's at a VRU, but it is the wrong VRU, the call is transferred
to the correct VRU.
Example Call Flows:
1. A call is moved to a Type 2 VRU via a Translation Route to VRU. The call can then be
moved to a Type 3 VRU via the SendToVRU node, if the Type 3 VRU is configured to
be the network VRU for this call.
2. A call arrives from a Type 6 VRU (CallAtVRU = true). SendToVRU then attempts to
send the call to the configured network VRU if the network VRU is different from the
routing client’s VRU.
3. SendToVRU fails the node if the transfer to the network VRU fails.
If the configuration is wrong or missing, (for example, if a network VRU is not
define, or proper label is not defined) then the fail path is executed and the call
remains at the VRU.
If the CallRouter succeeds in sending a Connect message, the CallRouter resets the
previous VRU information and waits for RequestInstruction to set up the new VRU
connection. If the operation times out, (RequestInstruction never arrives) then the
fail path of the SendToVru node is taken and the call is assumed not to be at a VRU.
The same behavior applies if CallRouter receives a ReRoute instead of a
RequestInstruction command.
4. A registry flag enables/disables this feature. The registry key is called
NetworkVRUCheckEnabled and is located at
...\Router\CurrentVersion\Configuration\Global. The default value is 1 (enabled), setting
it to 0 disables it.
Running External Scripts
You can instruct a Network VRU to run a specific script by using the Run External Script node
(in the Queue tab of the Palette).
Figure 80: The Run External Script Icon
You can use multiple Run External Script nodes to execute a series of scripts on the VRU.
The Run External Script node is valid for use with all the VRU types.
