Default dial string
The dial string is the actual string of characters sent to the CO to
place a call. Specify the dial string based on the dialing requirements
the CO has on your lines. For example, some areas may require you to dial
the area code for local calls. Using the Default Dial
String field, you can add the local area code as a prefix to
all local calls so CIC users do not need to dial the local area code.
As another example, some trunks may require a 1 or a 9
prefix before certain numbers, or add a prefix to specify a long distance
carrier (for example, 1010550). You can add any prefix (or
suffix) to any type of phone number using the Dial String
field. CIC client users do not have to dial the numbers you include as
a prefix in the Dial String field.
The dial string variable uses the same standardized format syntax described in Input pattern and output pattern syntax. You can use either the wildcard character syntax or the ordinal number syntax. However, if you use the wildcard characters, pay attention to the two conditions where you might have to use the ordinal number syntax in this field (see Conditions for using wildcard characters for details).
