ASAI drop event
Successful NCR call redirection causes an ASAI “drop” event to be sent to the CTI
application with a CV_REDIR cause value of decimal(30) after the redirection is
completed. Only one NCR “drop” event is received for a successful NCR operation when
the NCT PSTN feature is used, even though two trunks are dropped by the PSTN.
ASAI third-party merge/call transfer
The CTI application requests a third-party merge/call transfer ASAI operation to transfer
the call to the second communication server. This is only used if Network Call Transfer is
not available. Once the two calls merge, then ASAI sends a third-party acknowledgement,
and when the call is completed, ASAI sends a drop event report, and the third-party call
ends.
Interactions
Network Call Redirection interacts with several existing contact center features. The
features, and the effect NCR has on them, are described in this section.
NCR interacts with or affects the following communication server components:
●
station transfer by DCP set Transfer button/hangup or communication server hook flash
transfer by hangup
●
station transfer by DCP set Conference button, in which the conferencing (middle) party
connects the two calls and then hangs up
●
Station call transfer/conference — An incoming ISDN call over a trunk with NCT PSTN
service is answered at the station or VRU or IVR. The station user/VRU answers the call
and initiates a “station call transfer” using the transfer feature button or a communication
server hook flash. The DEIFNITY automatically sends the
invoke NCT
ISDN FACility
message when the transfer is complete only if NCT is assigned to the incoming trunk
group and the call is eligible for NCT. That is, if the second leg of the call has been set
up over a trunk with the same signaling group as the incoming call and the second leg
call has been answered. If the station user initiates and completes a three-way
conference instead, the communication server automatically sends an
invoke NCT
ISDN message when the initiating station user drops from the three-way conference.

ASAI third-party call transfer
●
ISDN trunk administration
●
Attendant Vectoring — Attendant Vectoring can use the
route-to number
vector step
with the ~r option to route calls to attendants located at another communication server
node. The operation of the NCR feature using the NCD or NCT networks features to
accomplish the call redirection is exactly the same as for redirecting ACD calls.
