288 Call Waiting Redirection

Direct Inward Dialing Call Forward No Answer Timer

The Direct Inward Dialing Call Forward No Answer Timer is applied after

the last stage of CFNA or SFNA treatment resulting from the Call Waiting

Redirection feature for DID Call Waiting calls.

Call Forward No Answer

The existing Distinctive Ringing Call Forward No Answer feature is applied

to calls from a Distinctive Ringing enabled trunk. If such an incoming call

is receiving Call Waiting treatment on sets with Distinctive Ringing, Call

Forward No Answer (CFNA), and the Call Waiting Redirection feature

enabled, the DFNA timer is applied to the call instead of the CFNA timer.

The Call Waiting warning tone, if enabled, is not changed by Distinctive

Ringing. If that call is not answered before the expiration of the DFNA timer,

CFNA treatment is given using the Call Waiting Redirection feature.

With the Call Waiting Redirection feature also enabled, the Call Waiting

Redirection feature takes precedence over Forward No Answer Call Waiting

Direct Inward Dialing (FCWD). The existing CFNA also takes precedence

over the existing Attendant Recall of Call Waiting calls. Since the Call

Waiting Redirection feature applies CFNA treatment to a Call Waiting call

while the FCWD feature applies an attendant recall timer, the Call Waiting

Redirection feature also has precedence over the FCWD timer.

Hunting

If Call Forward and Hunt by Call Type (CFCT) is enabled with Call Forward

No Answer and Call Waiting Redirection, "no answer" internal calls receiving

Call Waiting treatment are routed for CFNA treatment to the Flexible CFNA

DN (FDN) or Hunt DN, and "no answer" external calls are routed for CFNA

treatment to the External Flexible CFNA DN (EFD) or External Hunt DN

(EHT).

The option selected for Call Waiting Redirection treatment also applies to

calls given Internal Call Waiting treatment.

Unanswered calls given Call Waiting treatment may now be allowed to

forward to Voice Mail through the activation of the Call Waiting Redirection

feature. The greeting given to the caller is for a "no answer" condition.

Message Center

Unanswered calls given Call Waiting treatment may now be allowed by the

Call Waiting Redirection feature to be forwarded to a CFNA DN which may

be a Message Center. The call redirection reason is "no answer".
