Network Call Redirection Information

NCRI builds on the following call features:
• External Call Forward
• Call Transfer
• Call Forward
NCRI adds the ability to redirect a call across an MCDN
network using Call Forward (all calls, no answer, busy) and
Call Transfer features. The call destination also receives the
necessary redirection information. This feature allows the
system to automatically redirect calls from within a Norstar
system to the Meridian Mail system, which resides outside the
Norstar system on a Meridian 1 or another Norstar.
The figure below shows an example of this situation, where
user A calls user B on the same Norstar system. If user B is
busy or not answering, the call automatically gets transferred
to a Meridian Mail number (user C) across an MCDN link
between the Norstar system and the Meridian 1 system (or
another Norstar system) where the mailboxes are set up.
