Parameters
all: Specifies all calling numbers.
calling-string: Specifies the calling number permitted to originate a call to the local voice entity. The value
is a string of 1 to 31 characters and in the format of { [ + ] string [ $ ] }| $. Symbols in the format are
described as follows:
• Plus sign (+): The sign itself does not have special meanings. It only indicates that the following
string is an effective number and the number is E.164-compliant.
• Dollar sign ($): When it comes at the end of a number, the calling number must completely match
the part before the dollar sign. When it comes alone, the calling number can be null.
• If there is no sign behind the number, number segments beginning with it are permitted to originate
calls.
• string: A string consisting of any characters of digits 0 through 9, and pound sign (#), asterisk (*),
dot (.), exclamation point (!), plus sign (+), percent sign (%), brackets ([ ]), parentheses (()), and
hyphen (-).The characters in a string are described in the following table:

string

0-9 Digits 0 through 9.
Pound sign (#) and
asterisk (*)
Indicates a valid digit each.
Dot (.)
Wildcard, which can match any valid digit. For example, 555…. can match any
number beginning with 555 and ending in four additional characters.
Exclamation point (!)
Indicates the sub-expression before it appears once or does not appear. For example,
56!1234 can match 51234 and 561234.
The sub-expression (one digit or digit string) before an exclamation point (!) is used for
imprecise match. The processing of the sign is similar to that of the wildcard dot (.). This
sign must follow a valid digit or digit string and cannot exist independently.
