ParameterRangeDescription
StateN/A

Enable this flag to activate the Preconditions Profile configuration.

  • Disable (default)
  • Enable

NOTE: The remaining Preconditions Profile configuration options (listed below) are available once this preconditions State flag is enabled.

Support If Egress IPTGN/A

Enable this flag during session offer processing to have the

Spacevars
0product
assume preconditions support for entities on the egress trunk group.

  • Disable (default)
  • Enable

NOTE: The SBC does not associate semantics with this field from the ingress IPTG perspective.

Strength Mandatory PolicyN/A

Enable this flag for the

Spacevars
0product
to determine whether preconditions interworking is required on the ingress leg.

  • Disable (default)
  • Enable

NOTE: The precondition strength is mandatory in the precondition attribute and the Support If Egress IPTG flag is disabled.

Strength Optional PolicyN/A

Enable this flag to determine whether precondition inter-working is required on the ingress leg.

  • Disable (default)
  • Enable

NOTE: The precondition strength is optional in the precondition attribute and the SupportIfEgressIPTG flag is disabled.

UPDATEPreconditions PolicyNA

Enable this flag for the

Spacevars
0product
to indicate whether local preconditions are met with the initial INVITE or with a subsequent UPDATE on the egress leg.

  • Disable (default)
  • Enable

NOTE: This flag is significant when egress leg supports precondition based on the configuration.

Strength Mandatory Priority1-100

(Default = 1) Enter a value to specify the priority assigned to a call leg. This fields helps in resolving conflicts with selecting the policy.

If the StrengthMandatoryPriority flag is enabled on one call leg, but disabled on the other call leg, the

Spacevars
0product
considers the priority assigned to the policy on each call leg to select the policy and selects the policy with the higher priority.

When the two call legs have the same priority, the

Spacevars
0product
selects the policy on the ingress leg.

NOTE: Priority is inversely proportional to the value of digit. Lower the digit value, higher the priority. For example, priority 1 takes precedence over priority 2.

Strength Optional Priority1-100

(Default = 1) Enter a value to specify the priority assigned to a call leg. This parameter helps in resolving conflicts with selecting the policy.

If the StrengthOptionalPolicy flag is enabled on one call leg but disabled on the other call leg, the

Spacevars
0product
accounts the priority assigned to policy on each call leg to select the policy. The
Spacevars
0product
selects the policy which has higher priority.

When the two call legs have the same priority, the

Spacevars
0product
selects the policy on ingress leg.

NOTE: The priority is inversely proportional to the value of digit. The lower the digit value, the higher the priority. For example, priority 1 takes precedence over priority 2.

UPDATEPreconditions Priority1-100

(Default = 1) Enter a value to specify the priority assigned to a call leg. This field helps in resolving the conflicts with selecting the UPDATE policy. 

If the UPDATE policy is enabled on one call leg, but disabled on the other call leg, the

Spacevars
0product
considers the priority assigned to each UPDATE policy to select the UPDATE policy. In such cases, the
Spacevars
0product
selects the UPDATE policy with higher priority.

When the two call legs have the same priority, the

Spacevars
0product
selects the policy on ingress leg.

NOTE: The priority is inversely proportional to the value of digit. The lower the digit value, the higher the priority. For example, priority 1 takes precedence over priority 2.
