|
|---|---|
| Call Limit | Specifies the total number of calls allowed for egress. |
| 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. |
| Call Rate Max | Specifies the value of maximum allowed sustained egress rate (in calls/second) for egress call attempts. SBC 5400 / SWe - Range: 1-450, or unlimited. (The default value is unlimited.) SBC 7000 - Range: 1-1,350, or unlimited. (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 | Specifies the value of maximum allowed burst (above the allowed sustained rate) for egress call attempts in calls/second. SBC 5400 /SWe - Range: 1-900, or unlimited. (The default value is unlimited.) SBC 7000 - Range: 1-2,700, or unlimited. (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 | Specifies the maximum allowed sustained egress rate (registrations per second) for initial SIP registrations. (1-1500, or unlimited for SBC 5400; 1-3000, or unlimited for SBC 7000 series). The default value is unlimited. |
| Register Burst Max | Specifies the maximum allowed egress burst (above the allowed sustained rate) for initial SIP registrations. (1-1500, or unlimited for SBC 5400; 1-3000, or unlimited for SBC 7000 series). The default value is 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 %. |
