Call LimitSpecifies the total number of calls allowed for ingress. The value ranges from 0 to 2147483647 or unlimited.
Emergency OversubscriptionSpecifies 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 LimitThe 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 rate in calls/second for ingress 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.)

SBC 5400 / SWe - Range: 1-900, or unlimited. (The default value is unlimited.)
