Highlights of features and enhancements
Network Call Redirection
Network Call Redirection (NCR) provides the capability to have the public network
redirect an incoming call to another destination via Integrated Services Digital
Networking (ISDN), without occupying trunks between the DEFINITY and the
other location. The call redirection is invoked in real time on a call-by-call basis.
NCR uses either the ETSI Network Call Deflection (NCD) or ANSI Network Call
Transfer (NCT) features provided by the Public Switch Telephone Network
(PSTN) to redirect an incoming ISDN call from a DEFINITY to any other endpoint
via the PSTN. This optimizes the rerouting of ISDN calls over the public network,
because DEFINITY ECS trunks are not retained at the original destination after
the call rerouting takes place. Because fewer ISDN trunks are involved, the
customer realizes a cost savings.
NCR can be invoked by Best Service Routing (for NCD or NCT), Attendant
Vectoring or Call Vectoring through the “route-to
number
” command (for NCD or
NCT), Adjunct Switch Applications Interface (ASAI) Third-Party Merge/Call
Transfer using a CTI application (NCT only), or by agent or station transfers (NCT
only).
