Common errors
In CVP deployments, call failures at “Send to VRU” or “Run Ext Script” node are very common.
Voice Response Unit
VRU
Even though it is just a single node in ICM, there are lots of signaling events that need to occur on CVP, the VXML Gateway and/or VXML Server. There are a number of places configuration must be done correctly.
Most failures happen due to misconfiguration or a failure outside of ICM.
