Document Revision 1
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's routing. When the incoming call is forwarded to the first destination by a
busy intercept, the Voice Mail protocol will be that it forwards busy calls. When the incoming call is
routed to the first destination by a ring-no-answer intercept, the protocol will be that it forwards ring-
no-answer. The Voice Mail will transfer 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). If a valid DID number is not
entered, there will be no ring destination for any incoming calls to that number (the calls will not ring any
extension in the system).
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.
