Edit Egress - Parameter Description Table
| Parameter | Description |
|---|---|
| Call Limit | Total number of concurrent calls (0-2147483647, or unlimited), allowed on the egress leg. (default=unlimited) |
| Emergency Oversubscription | The percentage (0-1000) of resource oversubscription allowed for emergency calls. (default=10) |
| Hpc Oversubscription | This parameter specifies the amount of resource over-subscription (0-100), as a percentage, that are allowed for HPC. When the baseline call limit and bandwidth limit are reached, normal calls are not admitted, but additional HPC are allowed up to the configured percentage value. (default=10) |
| Call Rate Max | Maximum sustained egress call rate (1-1,350, or unlimited) allowed in calls per second. (default=unlimited) |
| Call Burst Max | Maximum allowed burst size (1-2,700, or unlimited) above the allowed sustained rate for egress call attempts, in calls per second. (default=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. |
Note
Call policing, using Call Rate Max and Call Burst Max, is applicable only to normal and emergency calls, and not to high priority calls (HPC).
