DID Intercept Destination for Each DID Number
With this feature the system allows you to program a DID Intercept destination for a DID number which
receives no answer or busy call. The system can be programmed to use a trunk ring group, the VRS or
the voice mail as the programmed destination. Each vacant number intercept for a DID number can
have two destinations. The first destination is for an invalid DID number, busy or no answer extension.
The second destination is for a no answer trunk ring group.
If the first programmed destination is a Ring Group and the second Destination is Voice Mail, the call does not
forward to VoiceMail.
For busy or no answer intercept calls, a third destination can be defined in Program 22-12. If the first
and third destinations are programmed but the second destination is not, the incoming call goes to the
third destination after the first destination. If the first and second destinations are not programmed, but
D
the third destination is, the call goes directly to the third destination.
This feature works for DID trunks with a trunk service type 3 in Program 22-02. Other types of trunks
may use the DID table, but the DID intercept feature is not yet supported.
With the DID Intercept for each DID number feature, when the primary destination (Program 22-11-05)
is set to Voice Mail, the Voice Mail protocol is:
1. Busy Intercept = Forward Busy
2. Ring-No-Answer Intercept = Forward RNA
When the secondary destination (Program 22-11-06) is set to Voice Mail, the Voice Mail protocol is
based on the first destination routing. When the incoming call is forwarded to the first destination by a
busy intercept, the Voice Mail protocol forwards busy calls. When the incoming call is routed to the first
destination by a ring-no-answer intercept, the protocol forwards ring-no-answer. The Voice Mail trans-
fers the calls to the mailbox number defined in Program 22-11-02.
Any valid DID number must be entered in the DID table (Program 22-11 or Program 22-17-01). If a valid
DID number is not entered, there is no ring destination for any incoming calls to that number (the calls do not
ring any extension in the system).
If the first programmed destination is a Ring Group and the second Destination is Voice Mail, the call does not
forward to VoiceMail.
Calls Can Follow Ring Group Programming for Transferring Calls
An option has been added to Program 22-11 which allows you to determine if the DID routing should
use the programmed ring group entry in Program 22-12-01 when transferring calls from a busy or no
answer number.
If DID digits match with the conversion table but there is no extension, no Voice Mail, or Voice Mail did
not boot up, use Program 22-11-11 to decide what to do with the incoming call. Go to (1) normal ring
(default) or (0) caller hears a Busy Tone.
