About Dialing Translation
There are situations when CallPilot generates an outbound call. For example, if a mailbox owner
replies to a Calling Line Identification (CLID) message. In this situation, CallPilot generates a
phone number to be dialed by the central office (CO).
Another example is when Network Reply or the Loopback mailbox is used. In these cases, the
phone number that is replied to is taken from information transmitted with the original message.
In both situations several changes must occur before the number is dialed through the local
telephone network. You must set up the Dialing Translation properties and create the Dialing
Translation Table to determine these changes.
How the Dialing Translation Table works
A phone number is derived from information attached to an incoming Caller ID message. The
number is then searched for in the Dialing Translation Table. If the leading digits of the telephone
number match a Dialing Translation Table Input value, the Output value is substituted for the
Input value. This change results in a telephone number that can be dialed on the local network.
Changing the number usually involves removing 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 do not take any longer to dial. Some
telephone numbers do not need to be changed before dialing. CallPilot can function without a
Dialing Translation Table except that the Reply feature cannot be used.
Phone number Translation
The Dialing Translation Table must define each possible case where a change is needed to allow
the number to be dialed on the local network.
The Dialing Translation Table changes Network extensions into numbers that can be dialed on the
local network. The Network extension form of a phone number is the usual form in which the
number appears. For example, the phone number 403-555-5050, in its Network extension form,
must be translated into a number that can be dialed on the local telephone network. The Dialing
Translation Table follows the rules required to make the call.
