(range: 1-1000, or unlimited. range is 1-3000, or unlimited). | Call Limit | Specifies the total number of concurrent calls (either ingress or egress) allowed on egress. The value ranges from 0 to 2147483647 or unlimited (default). | Emergency Oversubscription | Specifies the oversubscription of resources (as a percentage) that is allowed for emergency calls. The value ranges from 0 to 1000 and the default value is 10. | Extended Emergency IP Limit | The resource oversubscription (expressed as numeric value) allowed for emergency calls. The value ranges from 0 to 40000 with a default value of 0. | Subscribe Rate Max | Specifies the maximum sustained egress rate (subscribes per second) of initial SIP subscribe request. (range: 1-1000, or unlimited. range is 1-3000, or unlimited). | | Subscribe Burst Max | Specifies the maximum allowed burst (above the allowed sustained rate) for egress initial SIP subscribe request. (range: 1-1000, or unlimited. range is 1-3000, or unlimited) . | Other Req Rate Max | Specifies the maximum sustained egress rate (requests per second) of other out-of-dialog SIP requests. (range: 1-1000, or unlimited. range is 1-3000, or unlimited). | Other Req Burst Max | Specifies the maximum allowed burst (above the allowed sustained rate) for any other egress out-of-dialog SIP request. (range: 1-1000, or unlimited. range is 1-3000, or unlimited). | | Hpc Oversubscription | Specifies the over-subscription of the resources (in a percentage) that is allowed for HPC calls. When the baseline call limit and bandwidth limits are reached, normal calls are not admitted, but additional HPC calls are allowed up to the configured value percentage. The value ranges from 0 to 100 % and the default value is 10 %. |
