Replace <prefix> with the expected prefix for the call type. If you do not want
to specify a prefix, leave this option blank by entering double quotation marks
(""). Do not enter a space between the quotation marks. If you want to specify
a prefix, you can enter unlimited-length strings of 0s and 1s. For example, for
international calls made from within the United States, you might enter a
prefix of 011.
Specify a call type by entering one of the options listed in Table 8-11.

Use the options in Table 8-12 to specify a <pattern> for the call type.
Explanation
Specifies abbreviated (bits 110) in the Type of Number octet. This
option is used primarily for private ISDN network applications,
and the implementation is network-dependent.
Specifies international (bits 001) in the Type of Number octet. This
option is used for calls destined outside the national calling area.
Specifies national (bits 010) in the Type of Number octet. This
option is used for calls inside the national calling area. That is, the
calls do not cross an international local access and transport area
(LATA).
Specifies network-specific (bits 011) in the Type of Number octet.
This option is used for calls that require special access to a private
network. Because the prefix that must be stripped off once access
to the network has been gained, the dialing prefix is removed.
Specifies Subscriber (bits 100) in the Type of Number octet. This
option is used for intra-LATA calls (local calls). By default, the area
code is removed for these calls.
Specifies Unknown (bits 000) in the Type of Number octet. This
option is used if the actual types of the number are not known.
Unknown numbers are assumed to have no prefix, and the entire
dialed number is used.
