what is the difference between send to VRU node and Translation route to VRU node?
Thanks in advance
self service is an activity that doesn't request a user/agent interaction, VRU scripts could be invoked from a translation route or a send to vru.
Please be aware that translation to VRU timers are smaller then the send to vru, since all open translation route mean an open ICM dialogue and call object and the call to be eventually routed to an agent/target, while the send to vru assume an extensive interaction with the IVR.
Cisco is providing by the mean of Advanced Services a specific ICM scripting class I would recommend attending it for this and similar questions.
