Table 685 Description of characters in a string

Character Meaning

%Indicates the sub-expression before it appears multiple times or does not appear. For example, 9876(54)% can match 9876, 987654, 98765454, 9876545454, and so on.

[ ]	Indicates a range for matching. For example, [1-36A] indicates a single
	character among 1, 2, 3, 6, and A can be matched.
( )	Indicates a string of characters. For example, (123) indicates the character
	string 123. It is usually used together with signs such as !, %, or +. For
	example, 408(12)+ can match the character string 40812 or 408121212, but
	not 408 (that is, the string 12 can appear repeatedly and must appear once).

n The sub-expression (one digit or digit string) before signs such as !, %, and + is used for imprecise match. The processing of these signs is similar to that of the wildcard “.”. These signs must follow a valid digit or digit string and cannot exist independently.

If embedded, signs “[ ]” and “( )“ must be presented in the form of “( [ ] )“. The forms of “[ [ ] ]” and “[ ( ) ]” are incorrect.

The sign “-”can present itself only in “[ ]” and characters at the two ends must be of the same type.

Description Use the caller-permitcommand to configure a calling number permitted to originate calls to the local voice entity.

Use the undo caller-permitcommand to remove the configuration.

By default, no calling number is configured, that is, incoming calls are not restricted.

At most 32 calling numbers are permitted to originate calls to a voice entity.

Example # Configure voice entity 2 to accept calls from the number 660268.

<Sysname> system-view [Sysname] voice-setup [Sysname-voice] dial-program [Sysname-voice-dial] entity 2 pots

[Sysname-voice-dial-entity2] caller-permit 660268$

# Configure voice entity 2 to accept calls from the number beginning with “20”.

[Sysname-voice-dial-entity2] caller-permit 20
