Reserving outbound trunk B-channels to ensure NCR operations succeed

When the trunk group service type is set to call-by-call, the trunk group Usage Allocation capability can be used to reserve a minimum number of trunk channels for outgoing PRI B-channel calls within the same trunk group and same D-channel.

For more information, see Reserving trunk group B-channels for NCT-type redirection operations in the Administering Avaya Aura® Call Center Elite document.

Call Vectoring configuration required for successful MCI NCT operations

When NCR is used with the MCI NCT protocol, the VDN call vector the call is redirected to by a successful MCI NCT operation must immediately return an ISDN CONNECT message to the PSTN switch. To meet this requirement, either a wait 0 secs hearing music or an announcement vector step must be the first step executed in the redirected-to call vector.
