138 Chapter 9 Configuring addressing conventions and messaging service defaults
How the Call Sender feature uses dialing prefixes
Whenever a mailbox owner presses 9 while playing a message, CallPilot
must generate the DN to connect to the calling number. Whenever the
calling number is off-switch, CallPilot uses the configured dialing default
prefixes to handle normal dialing situations for local, national, international,
and (if they exist) ESN calls.

Handling mixed area or city codes

Whether an area code indicates a local or long distance number depends on
the calling location. In low-density population areas, a matching area code
indicates a local call and a different area code indicates a long distance call.
In high-density population areas, a call to an area with a different area code
is often treated as a local call because new area codes are introduced to
accommodate all the telephone numbers required for area residents.
When to define dialing translations for a mixed area code
When the area code is not sufficient to identify whether a call is local or long
distance, the combination of the area code and the local exchange is used
to make the distinction. If your CallPilot server is located in a high-density
population area use dialing translation definitions to identify the local area
code/local exchange combinations.
How dialing translation definitions are used
Dialing translation definitions are used primarily to translate an external
DN for playback to the mailbox owner and the Call Sender feature. For
example, if an Area Code/Exchange Code list is defined as long distance,
the message envelope playback includes the prefix 1.
Example
Andrei lives in Uxbridge and works in Markham, just north of Toronto. One
of Andrei's major customers is located in Toronto.

When a mailbox owner listens to a message delivered by a local call
over the public network and then invokes Call Sender to return the call,
CallPilot adds the prefix required to place off-switch calls (in North
America, this is typically 9).
When a mailbox owner listens to a message delivered by a call over
ESN and then invokes Call Sender to return the call, CallPilot adds the
prefix required to place an ESN call (for example, 6).
