•
Reject Max Origination Percentage—If the ingress carrier’s current percentage of calls is greater
than its provisioned maximum, the call is rejected.
Note
This rule rejects a call if the percentage of calls originated by this ingress carrier to a specific
route or match pattern exceeds the maximum percentage defined in the ingress route
attributes for this ingress carrier. For example, if the maximum percentage is set to 40
percent, the first call made by carrier A to route R succeeds and 100 percent of the calls to
route R are now made from ingress carrier A. The second call from the same carrier to the
same DNIS fails.
•
Reject Max Ingress Units—If the ingress carrier’s ingress units are greater than its provisioned
maximum, the call is rejected.
•
Reject Max Ingress Units Per Route—If the ingress carrier’s ingress units for this route are greater
than its provisioned maximum for this route, the call is rejected.
Note
The core CSR has not been customized for Call Minute Accounting. "Units" means "call
attempts". Once a specific carrier has attempted more calls than configured against "Max
Ingress Units" in the Carrier menu, its calls are rejected.
Step 7
In the Rejection Rules (Egress) area, check the checkbox to the left of the rule that you want to activate
as a rejection rule as follows:
•
Reject Egress Cost Greater Than Ingress—If the ingress carrier and egress carrier both have a
provisioned cost and the egress carrier’s cost is greater, the egress carrier is eliminated.
•
Reject Insufficient QoS—If the rule has the following elements, the egress carrier is eliminated:
–
A provisioned minimum QoS
–
The egress carrier has a QoS value available
–
The egress carrier’s QoS is worse (higher)
•
Reject Max Egress Units Exceeded—If the egress carrier’s egress units are greater than its
provisioned maximum, the carrier is eliminated.
•
Reject Max Egress Units Per Route Exceeded—If the egress carrier’s egress units for this route are
greater than its provisioned maximum for this route, the carrier is eliminated.
Note
The core CSR has not been customized for Call Minute Accounting. "Units" means "call
attempts". Once a specific carrier has attempted more calls than configured against "Max
Ingress Units" in the Carrier menu, its calls are rejected.
•
Prevent ITSP to ITSP—If the ingress carrier is an ITSP type, all egress carriers that belong to the
ITSP type are eliminated.
Step 8
In the Selection Rules area, check the checkbox next to the rule you want to activate.
Each selection rule must have an associated priority if it is selected. Valid priority levels are from 1 to
5. The following rules can be applied for selecting an egress carrier:
•
Select Min Cost Per Egress Route—Egress carriers without a cost value and sharing the lowest
provisioned cost are selected. All others are deselected.
•
Select Best QoS—Egress carriers without a QoS value and sharing the best provisioned QoS are
selected. All others are deselected.
