Digit Map Example 2 – PBX Emulation
Let’s say you are located in the 819 area code. You are in an office where you dial:
3 numbers to call one of your co-workers.
“9” to get an external line.
The following four possibilities are considered:
You are making an internal call to one of your co-workers.
You are making a long distance call outside the country.
You are making a long distance call outside your area code.
You are making a local call in the same area code.
Digit Map Rule #1
This digit map rule checks for internal calls.
Digit Map Rule #2
This digit map rule checks for calls outside the country.
Digit Map Rule #3
This digit map rule checks for long distance calls outside your area code.

The first digit “9” in the digit map indicates a user wants to make an
external call, while the second digit “1” indicates a user wants to call
outside his or her own area code (in North America). The two digits
must be removed because they do not need to be expressed to the
SIP Server. The SIP Server needs only to know the complete
number of the called party (CC+AC+directory number).
