User Guide

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.
