Name

Specifies the name of the SIP ARS Profile.

Use this parameter to define one or more response codes to treat as failure responses. Include one or more of the following values, separating each entry with a comma: - 400-699 - list codes individually

- all – include all response codes from 400-699

 - all4xx – include all 4xx response codes

 - all5xx – include all 5xx response codes

- all6xx – include all 6xx response.

Blk List
Algorithms

Specifies the type of BLACKLISTING ALGORITHM for this ARS profile:
• timeouts (default)—the timeout of the specified SIP message will be used for blacklisting the server. The algorithm TYPE, NUMBER OF TIMEOUTS, and DURATION attributes for this parameter must also be specified.
• retryafter—use the BLACKLISTING RETRYAFTER ALGORITHM TYPE (trigger)
as the blacklisting criteria.

You may configure either or both of these blacklisting criteria.

Blk List Alg
Timeouts Type

Specifies the TYPE of timeout trigger for the blacklisting TIMEOUTS algorithm:
• sip-invite—use SIP INVITE messages as a timeout trigger.

Blk List Alg
Timeouts Num Timeouts


Specifies the number of timeout events that must occur before black listing the address. Must be 1-3600; default value is 1.

Blk List Alg Timeouts Duration

Specifies the DURATION (in seconds) in which the specified number of timeouts should occur. Must be 1-3600. SIP-INVITE timeout is the only event that is supported as of now.

Blk List Alg Retry After Type

Specifies the SIP status code which has a Retry After value:
• sip-503

Use this parameter to control when to apply ARS to a mid-dialog request.

• Always - ARS is applied to all mid-dialog requests in a call.
• Never (default) - ARS is not applied to mid-dialog requests.
• Only If Not Black List Due to 503 - ARS is applied to mid-dialog requests unless blacklist due to 503 is encountered.


Recovery
Algorithm

Specifies the type of recovery algorithm used after an IP address has been blacklisted:
• probe (default)—the ARS initiates an active "ping" to the blacklisted server until it gets a response. Once a response is received, the address is removed from the blacklist. The METHOD, INTERVAL, NUMBER OF RESPONSES, and DURATION attributes for the this parameter must also be specified.
• timer—the ARS removes the entry for the blacklist after a configured duration.

Recovery Alg
Timer Duration

Specifies the DURATION (in seconds), for which the IP address will remain blacklisted. Must be 1-3600.

Recovery Alg
Probe Method

Specifies the probe (ping) METHOD for blacklist recovery:
• sip options—use a SIP OPTIONS request

Recovery Alg
Probe Interval

Specifies the probe INTERVAL (in seconds) for blacklist recovery. Must be 1 - 600 (default is 1).

Recovery Alg Probe Num Responses

Specifies the number of consecutive responses that must occur before removing an entry from the black list. Must be 1 - 32 (default is 1).

Recovery Alg
Probe Duration

Specifies the DURATION (in seconds) in which the specified number of probe responses should occur. Must be 1-3600 (default is 1).
