8
 
8, <:1212>xxxxxxx This is example is useful where a local area code is 
required by the carrier but the majority of 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 transmitting the number to the carrier.
U.S. long distance dialing:
EXAMPLE: ( [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:
EXAMPLE: ( [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 press 9, an 
external dial tone sounds. If the user enters an 11-digit number that starts 
with the digits 1900, the call is rejected.

xxxxxxx ! | 
9, 011xxxxxx. | 0 | [49]11 )
9, 011xxxxxx. After the user presses 9, an external dial tone sounds. The user 
can enter any number that starts with 011, as in an international call from the 
U.S. 
Informational numbers:
EXAMPLE: ( [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 )

character. The first sequence allows a user to dial 0 for an operator. The 
second sequence allows the user to enter 411 for local information or 911 
for emergency services.
