Message Waiting
Message Waiting has precedence over CFNA and Attendant Recall for
attendant-extended calls. Unanswered calls given Call Waiting treatment are
forwarded to the Flexible CFNA DN by the Call Waiting Redirection feature.
Multi-Party Operations
Recovery on Misoperation of Call Transfer - Call Transfer with
Ring No Answer (RGNA)
If the transferring party goes on-hook to complete the Call Transfer (that
is, blind transfer) before the "transferred to" or called party answers the
Call Waiting call, an RGNA Misoperation of Call Transfer is detected by
Multi-Party Operations (MPO).
With the Call Waiting Redirection feature enabled, if the blind transfer
completes after the CFNA timer applied by Call Waiting Redirection has
expired, there is no interaction as the Call Waiting Redirection feature is
done and has already redirected the unanswered Call Waiting call to the
CFNA DN.
If the blind transfer completes before the Call Waiting Redirection CFNA
timer expires and the RGNA option is defined to be:
1. Standard (STD, that is, operation as it was prior to introduction of MPO),
2. Non-STD (that is, ATN, DIS, OVF, AAR, or DAR), the RGNA option
Recovery on Misoperation of Call Transfer – Misoperation of Call Transfer
for All Other Cases
This type of misoperation occurs when the transferring party attempts to
complete the transfer in several other non-RGNA scenarios. There is no
interaction with these Multi-Party Operations scenarios and the Call Waiting
Redirection feature.
Multiple Appearance Directory Number
The Call Waiting Redirection feature applies to unanswered Call Waiting
calls which apply to single appearance DNs and primary appearance DNs
of Multiple Appearance.
Multiple Appearance Directory Number Redirection Prime
If the Multiple Appearance Directory Number Redirection Prime (MARP)
feature is activated, the Call Forward No Answer (CFNA) treatment given
by Call Waiting Redirection for an unanswered Call Waiting call follows the
MARP feature for CFNA treatment of calls to an idle DN.

there is no interaction, as Call Waiting Redirection will redirect the
unanswered Call Waiting call when the CFNA timer expires.
has precedence over CFNA and thus has priority over Call Waiting
Redirection's CFNA treatment.
