There are several instances when Norstar Voice Mail generates an outbound call.
One instance is when a mailbox subscriber replies to a Caller ID (Calling Line
Identification-CLID) message. In this situation, Norstar Voice Mail generates a
telephone number to be dialed by the public switched telephone network.
Another instance is when the Fax-on-demand two-call method is used. In this
situation, a caller enters the telephone number of the fax machine where
information is to be delivered. In a second call, Norstar Voice Mail transmits the
document. However, the telephone number entered by the caller may contain errors.
For example, the caller may forget to add the area code or add a long distance access
code when it is unnecessary.
In both instances several changes must occur before the number can be dialed
successfully through the local telephone network. The Dialing Translation Table
and Dialing Parameters determine these changes for the user.
How the Dialing Translation Table works
A telephone number is entered by a caller or is derived from information attached
to an incoming Caller ID message. The number is then looked up in the Dialing
Translation Table. If the leading digit or digits match a Dialing Translation Table
Input value, the number is then substituted for the Output value. This change results
in a telephone number that can be dialed on the local network. The changing of the
number usually consists of dropping an area code or inserting an access code, based
on the dialing rules of the local network. For example, if a local number is prefixed
with the long distance code “1”, it is removed by the Dialing Translation Table.
The Dialing Translation process is immediate so calls will not take any longer to
dial. Not all telephone numbers need to be changed before dialing. The Dialing
Translation Table is created by the System Coordinator.
