Parameters
calling-number-string: Specifies a calling number string of 1 to 31 characters that is in the format of [ + ] { regular-expression [ T ] [ $ ] | T }. The following describe the characters:
· Plus sign (+): If the plus sign (+) is at the beginning of the string, the string indicates an E.164 standard number. For example, +110022 indicates that 110022 is an E.164 standard number.
· Dollar sign ($): Can be used only at the end of the string. The number must exactly match the string before the dollar sign. If the string has no dollar sign, the number template matches all numbers starting with the string. For example, the answer-address 20 command matches all numbers starting with 20.
· T: Indicates the timer. The system waits for the subscriber to dial any number until one of the following events occurs:
¡ The number length threshold is exceeded.
¡ The subscriber enters the terminator.
¡ The timer expires.
· regular-expression: Specifies a matching pattern of characters. Table 1 lists the available characters.
Table 1 Description of the characters in a regular-expression
|
Character |
Description |
|
0-9 |
Digits 0 through 9. |
|
Pound sign (#) or asterisk (*) |
Indicates a valid digit. |
|
Dot (.) |
Wildcard, which can match any valid digit. For example, 555…. can match any 7-digit numbers beginning with 555. |
|
Exclamation point (!) |
Indicates that the preceding subexpression appears zero or one time. For example, 56!1234 can match 51234 and 561234. |
|
Plus sign (+) |
Indicates that the preceding subexpression appears one or more times. For example, 9876(54)+ can match 987654, 98765454, 9876545454, and so on. |
|
Percent sign (%) |
Indicates that the preceding subexpression appears zero or more times. For example, 9876(54)% can match 9876, 987654, 98765454, 9876545454, and so on. |
|
Hyphen (-) |
Connects two digits to indicate a range of numbers, for example, [1-9] indicates 1 to 9, inclusive. The hyphen (-) can appear only in brackets ([ ]). |
|
Brackets ([ ]) |
Indicates a range. Only numbers 0 through 9 are allowed in the range. For example, [1-36] matches 1, 2, 3, or 6. |
|
Parentheses (( )) |
Indicates a string of characters. For example, (123) indicates a character string of 123. It is usually used together with signs such as exclamation point (!), percent sign (%), and plus sign (+). For example, 408(12)+ can match the character string 40812 or 408121212, but not 408. In this pattern, 408 must be followed by one string of 12 at a minimum. |
|
|
NOTE: · An exclamation point (!), plus sign (+), or percent sign (%) must follow a valid digit or digit string. · To use brackets ([ ]) and parentheses (( )) together, use them in the form of "( [ ] )". The "( ( ) )", "[ [ ] ]", and "[ ( ) ]" forms are not allowed. |
Usage guidelines
If the calling number of an incoming call matches the calling number string for a voice entity, the voice entity becomes the incoming voice entity of the call.
Examples
# Configure the calling number string as 456 for VoIP entity 1 to match incoming calls.

Usage guidelines
A call can be established only when the calling party and the called party use the same codec.
You can use this command to directly configure a codec for a voice entity, or use the voice-class codec command to bind a codec template to a voice entity.
The g711alaw and g711ulaw codecs provide high-quality voice transmission but consume high bandwidth.
The g723r53 and g723r63 codecs provide silence suppression technology and comfortable noise as follows:
· The relatively high speed output is based on multipulse multiquantitative level technology and provides relatively high voice quality.
· The relatively low speed output is based on the Algebraic-Code-Excited Linear-Prediction technology and provides greater flexibility for applications.
The g729r8 and g729a codecs provide a voice quality (nearly toll quality) similar to the 32-kbps adaptive differential pulse code modulation (ADPCM). These two codecs feature low bandwidth, short delay, and medium processing complexity.

Indicates that the preceding subexpression appears zero or more times. For example, 9876(54)% can match 9876, 987654, 98765454, 9876545454, and so on. |
|
Hyphen (-) |
Connects two digits to indicate a range of numbers, for example, [1-9] indicates 1 to 9, inclusive. The hyphen (-) can appear only in brackets ([ ]). |
|
Brackets ([ ]) |
Indicates a range. Only numbers 0 through 9 are allowed in the range. For example, [1-36] matches 1, 2, 3, or 6. |
|
Parentheses (( )) |
Indicates a string of characters. For example, (123) indicates a character string of 123. It is usually used together with signs such as exclamation point (!), percent sign (%), and plus sign (+). For example, 408(12)+ can match the character string 40812 or 408121212, but not 408. In this pattern, 408 must be followed by one string of 12 at a minimum. |
|
|
NOTE: · An exclamation point (!), plus sign (+), or percent sign (%) must follow a valid digit or digit string. · To use brackets ([ ]) and parentheses (( )) together, use them in the form of "( [ ] )". The "( ( ) )", "[ [ ] ]", and "[ ( ) ]" forms are not allowed. |

Usage guidelines
You can set the DSCP value for IP packets carrying media streams both globally (in SIP view) and for a specific voice entity (in POTS/VoIP entity view). The configuration in POTS/VoIP entity view takes precedence over the global configuration. A voice entity uses the global configuration only when the ip qos dscp command is not configured in POTS/VoIP entity view.

Parameters
match-string: Specifies a number template, a string of 1 to 31 characters that is in the format of [ + ] { string [ T ] [ $ ] | T }. The following describe the characters:
· Plus sign (+): If the plus sign (+) is at the beginning of the string, the string indicates an E.164 standard number. For example, +110022 indicates that 110022 is an E.164 standard number.
If a number starts with the plus sign (+), note the following when you use it on a trunk:
¡ The E&M, R2, and LGS signaling methods use DTMF transmission. Because the plus sign (+) does not have a DTMF tone, the number cannot be transmitted to the called side successfully.
¡ Because the DSS1 signaling uses ISDN transmission, this problem does not exist.
¡ You should avoid using a number that cannot be identified by the signaling itself. Otherwise, the call will fail.
· Dollar sign ($): Can be only at the end of the string. The number must exactly match the string before the dollar sign. If the string has no dollar sign, the number template matches all numbers starting with the string. For example, the match-template 20 command matches all numbers starting with 20.
· T: Indicates the timer. The system waits for the subscriber to dial any number until one of the following conditions occurs:
¡ The number length threshold is exceeded.
¡ The subscriber enters the terminator.
¡ The timer expires.
· string: Specifies a matching pattern of characters. Table 10 lists the available characters.
Table 10 Description of the characters in a string

0-9 |
Digits 0 through 9. |
|
Pound sign (#) or asterisk (*) |
Indicates a valid digit. |
|
Dot (.) |
Wildcard, which can match any valid digit. For example, 555…. can match any 7-digit numbers beginning with 555. |
|
Exclamation point (!) |
Indicates that the preceding subexpression appears zero or one time. For example, 56!1234 can match 51234 and 561234. |
|
Plus sign (+) |
Indicates that the preceding subexpression appears one or more times. For example, 9876(54)+ can match 987654, 98765454, 9876545454, and so on. |
|
Percent sign (%) |
Indicates that the preceding subexpression appears zero or more times. For example, 9876(54)% can match 9876, 987654, 98765454, 9876545454, and so on. |
|
Hyphen (-) |
Connects two digits to indicate a range of numbers, for example, [1-9] indicates 1 to 9, inclusive. The hyphen (-) can appear only in brackets ([ ]). |
|
Brackets ([ ]) |
Indicates a range. Only numbers 0 through 9 are allowed in the range. For example, [1-36] matches 1, 2, 3, or 6. |
|
Parentheses (( )) |
Indicates a string of characters. For example, (123) indicates a character string of 123. It is usually used together with signs such as exclamation point (!), percent sign (%), and plus sign (+). For example, 408(12)+ can match the character string 40812 or 408121212, but not 408. In this pattern, 408 must be followed by one string of 12 at a minimum. |
|
|
NOTE: · An exclamation point (!), plus sign (+), or percent sign (%) must follow a valid digit or digit string. · To use brackets ([ ]) and parentheses (( )) together, use them in the form of "( [ ] )". The "( ( ) )", "[ [ ] ]", and "[ ( ) ]" forms are not allowed. |

Parameters
adaptive: Specifies the playout delay mode as adaptive. In adaptive mode, the buffer size is automatically adjusted based on network conditions.
fixed: Specifies the playout delay mode as fixed. In fixed mode, the buffer size is fixed.
Usage guidelines
In an ideal voice network environment, the delay of each voice packet (time for each voice packet to travel from the sender to the receiver) is fixed. That is, the jitter is 0. In an actual voice network, the delay might vary from packet to packet.
To smoothly play out voice packets received with different delay times, the receiver can buffer the voice packets for a period of time (playout delay time). By configuring playout delay, you can prevent delay variation (jitter) from affecting voice quality.

Views
Voice view
Predefined user roles
network-admin
Parameters
time: Specifies the maximum duration of DSP-buffered data, in milliseconds. The value range for this argument is 0 and 10 to 480. If you set the maximum duration of DSP-buffered data to 0 milliseconds, the device does not clear the DSP buffer.
Usage guidelines
VoIP voice data is buffered in the DSP buffer if a network latency or jitter exists. When the maximum duration of DSP-buffered data is reached, the device clears the DSP buffer to improve the quality of VoIP calls. You can use this command to adjust the maximum duration of DSP-buffered data.
When PCM pass-through is enabled, the set maximum duration of DSP-buffered data takes effect.
When PCM pass-through is disabled, one of the following rules applies:
· If the set maximum duration of DSP-buffered data is in the range of 10 to 179 milliseconds, the default value (270 milliseconds) takes effect.
· If the set maximum duration of DSP-buffered data is 0 or in the range of 180 to 480 milliseconds, the set value takes effect.
For more information about PCM pass-through, see voice interface configuration in Voice Configuration Guide.
