cscfBlacklistingBypassThrottle
=
100
-
This parameter controls how much of initial SIP requests should be sent to destinations that have been blacklisted as unreachable due to a SIP 503 with Retry-After. It is possible to define the percentage of requests that should be sent in this case. Note that as long as at least one destination transport address is not blacklisted, that address will be used and this parameter has no effect. If cscfBlacklistingBypassThrottle has the value 0, it means that CSCF will not overrule blacklisting for destinations blacklisted due to SIP 503 with Retry-After. The unreachable destination transport address is blacklisted for a configurable period of time (cscfDestinationUnavailabilityTimer). If blacklisting reason is SIP 503 with Retry-After and cscfBlacklistingBypassThrottle has the value 100, it means that no matter for how long the node is blacklisted, the CSCF will try to send initial SIP requests towards it in 100% of the cases (that is, ignore the blacklisting completely).
If cscfBlacklistingBypassThrottle has another value, for example 70, it means that 70% of all requests will disregard the blacklisting and the initial SIP requests will be sent anyway.

cscfBlacklistingInsideDialogRequestBypassThrottle
=
100
-
This parameter controls how much of inside dialogue SIP requests should be sent to destinations that have been blacklisted as unreachable. It is possible to define the percentage of inside dialogue SIP requests that should be sent in this case. Note that as long as at least one destination transport address is not blacklisted, that address will be used and this parameter has no effect.
If cscfBlacklistingInsideDialogRequestBypassThrottle has the value 0, it means that CSCF will not overrule blacklisting for any inside dialogue SIP request. How long a destination is blacklisted depends on the reason why it was blacklisted. If cscfBlacklistingInsideDialogRequestBypassThrottle has the value 100, it means that no matter what the reason is, and for how long the node is blacklisted, the CSCF will try to send inside dialogue SIP requests towards it in 100% of the cases (that is, ignore the blacklisting completely).
If cscfBlacklistingInsideDialogRequestBypassThrottle has another value, for example 70, it means that 70% of all requests will disregard the blacklisting and the requests will be sent anyway.

cscfBlacklistingSip503WithoutRetryAfterBypassThrottle
=
100
-
This parameter controls how much of initial SIP requests should be sent to destinations that have been blacklisted as unreachable due to a SIP 503 without Retry-After. It is possible to define the percentage of requests that should be sent in this case. Note that as long as at least one destination transport address is not blacklisted, that address will be used and this parameter has no effect.
If cscfBlacklistingSip503WithoutRetryAfterBypassThrottle has the value 0, it means that CSCF will not overrule blacklisting for destinations blacklisted due to SIP 503 without Retry-After. The unreachable destination transport address is blacklisted for a configurable period of time (cscfDestinationUnavailabilityTimer). If blacklisting reason is SIP 503 without Retry-After and cscfBlacklistingSip503WithoutRetryAfterBypassThrottle has the value 100, it means that no matter for how long the node is blacklisted, the CSCF will try to send requests towards it in 100% of the cases (that is, ignore the blacklisting completely). If cscfBlacklistingSip503WithoutRetryAfterBypassThrottle has another value, for example 70, it means that 70% of all requests will disregard the blacklisting and the requests will be sent anyway.

-
cscfBlacklistingSipTransactionTimeoutBypassThrottle
=
100
-
This parameter controls how much of initial SIP requests should be sent to destinations that have been blacklisted as unreachable due to a SIP Transaction Timeout. It is possible to define the percentage of requests that should be sent in this case. Note that as long as at least one destination transport address is not blacklisted, that address will be used and this parameter has no effect.
If cscfBlacklistingSipTransactionTimeoutBypassThrottle has the value 0, it means that CSCF will not overrule blacklisting for destinations blacklisted due to SIP Transaction Timeout. The unreachable destination transport address is blacklisted for a configurable period of time (cscfDestinationUnavailabilityTimer). If blacklisting reason is SIP Transaction Timeout and cscfBlacklistingSipTransactionTimeoutBypassThrottle has the value 100, it means that no matter for how long the node is blacklisted, the CSCF will try to send requests towards it in 100% of the cases (that is, ignore the blacklisting completely). If cscfBlacklistingSipTransactionTimeoutBypassThrottle has another value, for example 70, it means that 70% of all requests will disregard the blacklisting and the requests will be sent anyway. NOTE: This parameter is a sequence with only one element. To change its value with the ECLI use one of these syntax:
cscfBlacklistingSipTransactionTimeoutBypassThrottle[@1]=<new_value>
cscfBlacklistingSipTransactionTimeoutBypassThrottle[<old_value>]=<new_value>

cscfBlacklistingSipTransactionTimeoutThreshold
=
0
-
This parameter is used to configure the threshold value for blacklisting destinations due to the reason of SIP transaction timeout.
|
BlacklistingThresholdIntervalDT |
-
cscfBlacklistingThresholdInterval
=
0
-
This attribute defines the measurement period in seconds for blacklisting thresholds. This attribute is applicable for the following SIP blacklisting reasons: SIP 503 Response with Retry-After, SIP 503 Response without Retry-After, SIP transaction timeout and fatal transport error (socket error). The default value is 0, which means cscfDestinationUnavailabilityTimer or cscfDestinationUnavailabilityTimerDest is used as both measurement period and blacklisting period. This attribute is not access aware.

-
cscfBlacklistingTransportErrorBypassThrottle
=
100
-
This parameter controls how much of initial SIP requests should be sent to destinations that have been blacklisted as unreachable due to Fatal Transport Error or ICMP Error. It is possible to define the percentage of requests that should be sent in this case. Note that as long as at least one destination transport address is not blacklisted, that address will be used and this parameter has no effect.
If cscfBlacklistingTransportErrorBypassThrottle has the value 0, it means that CSCF will not overrule blacklisting to destinations blacklisted due to Fatal Transport Error or ICMP Error. The unreachable destination transport address is blacklisted for a configurable period of time (cscfDestinationUnavailabilityTimer). If blacklisting reason is Fatal Transport Error or ICMP Error and cscfBlacklistingTransportErrorBypassThrottle has the value 100, it means that no matter for how long the node is blacklisted, the CSCF will try to send requests towards it in 100% of the cases (that is, ignore the blacklisting completely). If cscfBlacklistingTransportErrorBypassThrottle has another value, for example 70, it means that 70% of all requests will disregard the blacklisting and the requests will be sent anyway.
