Description
64
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 for-
wards ring-no-answer. The Voice Mail will transfer the calls to the mailbox number defined in Pro-
gram 22-11-02.
Note: 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 num-
ber (the calls will not ring any extension in the system).
Federal Communications Commission DID Requirements
Allowing this equipment to operate in a manner that does not provide proper answer supervision
signaling is in violation of Part 68 rules.
This equipment returns answer supervision to the Public Switched Telephone Network when the
DID trunk is:
Answered by the called station
Answered by the attendant
Routed to a recorded announcement that can be administered by the CPE user
Routed to a dial prompt
This equipment returns answer supervision on all DID calls forwarded back to the Public Switched
Telephone Network. Permissible exceptions are when:
A call is unanswered
A busy tone is received
A reorder tone is received
When ordering DID service, provide the telco with the following information:
A Direct Inward Line (DIL) is a trunk that rings an extension, virtual extension or Department
Group directly. Since DILs only ring one extension or group (i.e., the DIL destination), employees
always know which calls are for them. For example, a company operator can have a Direct Inward
Line for International Sales Information. When outside callers dial the DIL's phone number, the call
rings the operator on the International Sales line key. The DIL does not ring other extensions.
DIL Delayed Ringing
Extensions in a Ring Group can have delayed ringing for another extension's DIL. If the DIL is not
answered at its original destination, it rings the DIL No Answer Ring Group. This could help a
Technical Service department, for example, that covers calls for an Inside Sales department. If the
Inside Sales calls are not answered, they ring into the Technical Service department.
