Usage guidelines

To establish a call, you must make sure the calling party and the called party use the same codec.

If you execute this command multiple times, the most recent configuration takes effect.

You can use this command to directly configure a codec for a register pool, or use the voice-class codec command to apply a codec template to a register pool.

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. The g723r63 codec is based on multipulse multiquantitative level technology and provides relatively high voice quality. The g723r53 codec 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.

Predefined user roles

network-admin

Parameters

ip ip-address: Specifies a SIP UA by its IP address.

network network: Specifies SIP UAs on an IP subnet.

mask { mask-length | mask }: Specifies the subnet mask of the IP subnet. The mask-length argument represents the subnet mask length. The mask argument represents the subnet mask in the range of 0 to 32. If you do not specify this option, the system uses the subnet mask is 0.0.0.0, and all SIP UAs are not permitted to register.

mac mac-address: Specifies a SIP UA by its MAC address in the format of H-H-H.

Usage guidelines

You can configure SIP UAs that can register based on address by using the id command or based on number by using the number command. You must configure either of the commands for a register pool. If you configure both of them for a register pool, only SIP UAs with matching addresses and phone numbers can register.

If you configure an id command for a register pool already configured with the number command, the system deletes all existing dynamic VoIP entities.

number: Specifies a string of 1 to 31 characters that can include digits 0 through 9 and dollar sign ($). The dollar sign ($) is a terminator, and can be used only at the end of the string. The register number must exactly match the portion of the string before the dollar sign.

Usage guidelines

A register number template defines a template for numbers that can register with the voice server. For example, if you execute the number 1000 command, all numbers beginning with 1000 (such as 10001, 10002, and 10003) can register with the voice server. If you execute the number 1000$ command, only number 1000 can register with the voice server.

You can configure only one register number template for a DN.

Examples

# Configure the register number template as 1000 for DN 100.

<Sysname> system-view

[Sysname] voice-setup

[Sysname-voice] voice register dn 100

Predefined user roles

network-admin

Parameters

tag: Specifies a tag for a group of numbers that can register, in the range of 1 to 10.

number: Specifies a register number template, a string of 1 to 31 characters that can include digits 0 through 9 and dollar sign ($).The dollar sign ($) is a terminator, and can be used only at the end of the string. The register number must exactly match the portion of the string before the dollar sign.

dn dn-tag: Specifies an existing DN by its DN tag in the range of 1 to 200. The command permits all numbers in the DN to register.

Usage guidelines

You can configure SIP UAs that can register based on address by using the id command or based on number by using the number command. You can configure either or both of the commands for a register pool. If you configure both of them for a register pool, only SIP UAs with matching addresses and phone numbers can register.

This command deletes existing dynamic VoIP entities that are created based on addresses and do not match the register number template in the register pool.

A register number template defines a template for numbers that can register with the voice server. For example, if you execute the number 1000 command, all numbers beginning with 1000 (such as 10001, 10002, and 10003) can register with the voice server. If you execute the number 1000$ command, only the number 1000 can register with the voice server.

You can configure a maximum of 10 groups of numbers that can register for a register pool.

Predefined user roles

network-admin

Parameters

expires: Specifies the global registration expiration time.

max: Specifies the global maximum registration expiration time in the range of 120 to 86400 seconds. The default is 3600 seconds.

min: Specifies the global minimum registration expiration time in the range of 60 to 3600 seconds. The default is 60 seconds.

Usage guidelines

This command enables the device to process SIP register messages as a SIP registrar. If the registration expiration time in register messages is not in the configured range, the registrar notifies SIP UAs of the acceptable range.

If you disable SIP registrar, the voice server denies new register messages. Existing registration information is removed until the registration expiration time is reached.

If you do not configure the registration expiration time in register pool view, the global configuration in SIP view applies. If you configure the registration expiration time in both register pool view and SIP view, the configuration in register pool view takes priority.

Examples

# Enable the SIP registrar and set the maximum and minimum registration expiration time to 3000 and 100 seconds, respectively.

Usage guidelines

DNs allow you to make configurations specific to SIP UAs with matching phone numbers. Dynamic VoIP entities created for these numbers inherit the configurations in the DN rather than those in the register pool.

For example, dynamic VoIP entities are created for IP phones on the subnet 10.1.1.0 in a register pool. The priority of the dynamic VoIP entities in the register pool is 3. To change the priority only for the dynamic VoIP entities created for number 1000 to 1, perform the following tasks:

1.     Create a DN.

2.     Set the register number template for the DN to 1000.

3.     Set the priority of dynamic VoIP entities in the DN to 1.

4.     Apply the DN to the register pool.

Parameters

pool-tag: Specifies a register pool by its tag in the range of 1 to 200.

Usage guidelines

A register pool contains registration requirements that define which SIP UAs can register and also maintains registration information of SIP UAs. If a SIP UA meets the registration requirements, it can successfully register with the voice server, and dynamic VoIP entities are created.

The undo form of this command deletes all existing dynamic VoIP entities in the register pool.

Parameters

tag: Specifies a codec template by its tag in the range of 1 to 2147483647.

Usage guidelines

To establish a call, you must make sure the calling party and the called party use the same codec.

You can apply a nonexistent codec template to a register pool. The codec template takes effect only after you assign priorities to codes in the template by using the codec preference command.

You can apply only one codec template to a register pool. If you configure the command multiple times, the most recent configuration takes effect.

You can use this command to apply a codec template to a register pool, or use the codec command to directly configure a codec for a register pool.

Examples

# Apply codec template 1 to register pool 100.

Use undo voice-class sip options-keepalive to restore the default.

Syntax

voice-class sip options-keepalive [ up-interval interval ] [ down-interval interval ] [ retry retries ]

undo voice-class sip options-keepalive

Default

The up-interval is 60 seconds, the down-interval is 30 seconds, and the retry is 5 times.

Views

Register pool view

Predefined user roles

network-admin

Parameters

up-interval interval: Specifies the interval for sending OPTIONS packets when the remote voice server is available, in the range of 5 to 1200 seconds.

down-interval interval: Specifies the interval for sending OPTIONS packets when the remote voice server is unavailable, in the range of 5 to 1200 seconds.

retry retries: Specifies the number of retries to change the state for the remote voice server. The value range for the option is 1 to 10.

Usage guidelines

After you enable keepalive by using the proxy command, the local survivable voice server sends OPTIONS packets at the up-interval. If the local survivable voice server receives a response within the up-interval, it marks the remote voice server as available. If the local survivable voice server receives no response within the up-interval, or receives an error response, it sends OPTIONS packets at the timers options interval. (Error responses include 408, 499, and 5XX responses except for 500, 501, 502, 503, 504, and 513 responses.) If the local survivable voice server still receives no responses after the maximum number of retries is reached, it marks the remote voice server as unavailable.

Then, the local survivable voice server sends OPTIONS packets at the down-interval. If the local survivable voice server receives a response within the down-interval, it sends OPTIONS packets at the timers options interval. If the local survivable voice server still can receive responses after the number of retries is reached, it marks the remote voice server as available.

Examples

# In register pool 100, set the up-interval to 50 seconds, the down-interval to 20 seconds, and the number of retries to 2.

pattern: Specifies a number template for called numbers to be blocked, a string of 1 to 31 characters. Table 5 shows the characters that can be included in the string and their descriptions.

Table 5  Descriptions of characters

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.

 

7-24: Enables call blocking 7 days a week, 24 hours a day. If you do not specify this keyword, the command blocks incoming calls during the time period specified by using the after-hours day or after-hours date command.

Usage guidelines

If a number matches multiple number templates, only the template with the smallest tag applies.

In a register pool, call blocking takes priority over DND, and DND takes priority over call forwarding.

Examples

# Enable call blocking for number 1000 for 7 days a week, 24 hours a day.

Parameters

month: Specifies a month, a case-insensitive string, which can be January, February, March, April, May, June, July, August, September, October, November, and December. The string must contain a minimum of the first three letters of a month, for example, Jan.

date: Specifies a date of the month, in the range of 1 to 31.

start-time: Specifies the start time for call blocking, in the format of hh:mm (24-hour clock). The value 24:00 is invalid.

stop-time: Specifies the end time for call blocking, in the format of hh:mm (24-hour clock). The value 24:00 is invalid. If you specify 00:00, the system uses the value 23:59.

Usage guidelines

This command takes effect only when call blocking is enabled.

If you specify 00:00 for both the start time and end time, call blocking is enabled for 24 hours of the specified date.

If the end time is less than the start time, call blocking lasts to the end time of the day after the specified date.

If you also configure the after-hours day command, the time period for call blocking is the union of time periods specified in the two commands.

If you execute this command multiple times for the same day of the same month, the most recent configuration takes effect.

Parameters

all: Enables call forwarding unconditional.

busy: Enables call forwarding busy.

noan: Enables call forwarding no reply.

unregistered: Enables call forwarding unregistered.

timeout: Triggers call forwarding no reply.

number: Specifies a forward-to number, a string of 1 to 31 digits that can include digits 0 through 9.

seconds: Specifies the timeout time for no reply, in the range of 3 to 120 seconds. The default is 20 seconds.

Usage guidelines

For this command, you can specify the all, busy, and noan options in register pool view and DN view. You can specify the unregistered option only in DN view.

For a dynamic VoIP entity, call forwarding unconditional takes priority over call forwarding busy, and call forwarding busy takes priority over call forwarding no reply. Call forwarding unregister cannot coexist with the three types of call forwarding.

You need to correctly plan forward-to numbers to avoid circular calls.

To avoid call forwarding loops, you can configure a maximum of five forward-to numbers for a call.

In a register pool, call blocking takes priority over DND, and DND takes priority over call forwarding.

Examples

# Enable call forwarding busy for number 5000 and set the forward-to number to 8000.

<Sysname> system-view
