ISSUE 1.0
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 PRG 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 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 PRG 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 (PRG 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 (PRG 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
transfers the calls to the mailbox number defined in PRG 22-11-02.
Any valid DID number must be entered in the DID table (PRG 22-11 or PRG 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 PRG 22-11 which allows you to determine if the DID routing should use
the programmed ring group entry in PRG 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 PRG 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.
DID Call by Time Schedule
DID Call by Time Schedule allows for 500 programmed DID Conversion table entries (PRG 22-17-01)
that can be routed based on Time Patterns. Each DID Conversion table has a maximum of eight
programmable Time Patterns and each Time Pattern can reference one of the 1000 different Dial-In
Conversion table entries in PRG 22-11-01.
