I doubt that this call flow would support Network Transfer:
Call is bridged & translation routed by NIVR (Type 5) to a Premise IVR. when call is Translation routed to Premise VRU(i assume this is Type 2), we
lose some important data (NICCallID info).
Premise IVR makes a translation route request (and a Network transfer) to ICM. this Request should include valid NICCallID data but it can't since we lost
the data in step 3. to make sure that the call flow doesn't work, please capture some logs that show the message flow between several components:
Router logs with 'Route Request', 'NetworkVRU' and 'Translation Route' trace bits enabled. - INCRP log with EMSTraceMask of 0x200
OPC logs; i'm not sure what debug flags are needed here, but I like to see the content of NewCall message that is generated in
