( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
• Extensions on your system:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
[1-8]xx
Allows a user to dial any three-digit number that starts with the digits 1 to 8. If your system
uses four-digit extensions, enter the following string:
[1-8]xxx
• Local dialing with seven-digit number:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]111)
9, xxxxxxx
After a user presses 9, an external dial tone sounds. The user can enter any seven-digit
number, as in a local call.
• Local dialing with 3-digit area code and a 7-digit local number:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
9, <:1>[2-9]xxxxxxxxx
This example is useful where a local area code is required. After a user presses
9, an external dial tone sounds. The user must enter a 10-digit number that begins with a digit 2 through
9. The system automatically inserts the 1 prefix before it transmits the number to the carrier.
• Local dialing with an automatically inserted 3-digit area code:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
8, <:1212>xxxxxxx
This example is useful where a local area code is required by the carrier but most
calls go to one area code. After the user presses 8, an external dial tone sounds. The user can enter any
seven-digit number. The system automatically inserts the 1 prefix and the 212 area code before it transmits
the number to the carrier.
• U.S. long-distance dialing:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
9, 1 [2-9] xxxxxxxxx
After the user presses 9, an external dial tone sounds. The user can enter any
11-digit number that starts with 1 and is followed by a digit 2 through 9.
• Blocked number:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
9, 1 900 xxxxxxx !
This digit sequence is useful if you want to prevent users from dialing numbers
that are associated with high tolls or inappropriate content, such as 1-900 numbers in the U.S. After the
user presses 9, an external dial tone sounds. If the user enters an 11-digit number that starts with the
digits 1900, the call is rejected.
