Use the following table to configure and then click Save.
Parameter | Length/Range | Description |
|---|---|---|
Call Rate Max | unlimited or
| Specifies the value of maximum allowed sustained calls/second for egress call attempts. The default value is unlimited. Note: You can set both Call Burst Max and Call Rate Max as unlimited; however, if you assign a value to one parameter, the other must also be assigned a value. |
Call Burst Max | unlimited or
| Specifies the value of the maximum allowed burst (above the allowed sustained rate) for egress call attempts in calls/second. The default value is unlimited. Note: You can set both Call Burst Max and Call Rate Max as unlimited; however, if you assign a value to one parameter, the other must also be assigned a value. |
Register Rate Max | unlimited or
| Specifies the maximum allowed sustained egress rate (registrations per second) for initial SIP registrations. The default value is unlimited. Note: You can set both Register Burst Max and Register Rate Max as unlimited; however, if you assign a value to one parameter, the other must also be assigned a value. |
Register Burst Max | unlimited or
| Specifies the maximum allowed egress burst (above the allowed sustained rate) for initial SIP registrations. The default value is unlimited. |
Call Limit | 0-2147483647 | Specifies the total number of concurrent calls (either ingress or egress) allowed on egress. The default is unlimited. |
Emergency Oversubscription | 0-1000 | Specifies the oversubscription of resources (as a percentage) that is allowed for emergency calls. The default value is 10. |
Extended Emergency IP Limit | 0-40000 | The resource oversubscription (expressed as a numeric value) allowed for emergency calls. The default value is 0. |
Subscribe Rate Max | unlimited or
| Specifies the maximum sustained egress rate (subscribes per second) of the initial SIP subscribe request. The default value is unlimited. |
| Subscribe Burst Max | unlimited or
| Specifies the maximum allowed burst (above the allowed sustained rate) for egress initial SIP subscribe request. The default value is unlimited. |
Other Req Rate Max | unlimited or
| Specifies the maximum sustained egress rate (requests per second) of other out-of-dialog SIP requests. The default value is unlimited. |
Other Req Burst Max | unlimited or
| Specifies the maximum allowed burst (above the allowed sustained rate) for any other egress out-of-dialog SIP request. The default value is unlimited. |
| Hpc Oversubscription | 0-100 | Specifies the over-subscription of the resources (as 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 default value is 10. |
