Dialing Translation
About Dialing Translation
Dialing translation is a process by which the number of an incoming call from a public network is
translated by a translation table into a number that can be recognized and dialed on the local
network using the Reply feature.
For Dialing Translation to occur, you must create a Dialing Translation Table that recognizes the
digits of an external number and translates them into a number that can be dialed by the system.
The business telephone system also consults the restrictions and schedules tables prior to dialing
the number.
The Dialing Translation Tables are necessary only for the Reply feature. CallPilot does not require
the tables in order to function normally.
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 by the CallPilot in the Dialing Translation Table. If the leading digits
of the telephone number match a Dialing Translation Table Input value (the number CallPilot
searches for in the Dialing Translation Table), 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 functions without a Dialing
Translation Table.
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.
