| Call Burst Max | unlimited or
| Specifies the value of the maximum allowed burst (above the allowed sustained rate) for ingress 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

Register Burst Max | unlimited or
| Specifies the maximum allowed ingress burst (above the allowed sustained rate) for initial SIP registrations. The default value is unlimited. |
Call Limit | unlimited or 0-2147483647 | Specifies the total number of concurrent calls (either ingress or egress) allowed on ingress. The default is unlimited. |
