Default value is "0" which indicates no video threshold value. | | Emergency Oversubscription | The oversubscription of resources (as a percentage) that is allowed for emergency calls. | | Extended Emergency IP Limit | Additional number of emergency calls (expressed as a numeric value) allowed if call limit and emergency oversubscription quota are exhausted. The value ranges from 0 to 40000 and the default value is 0. | Registration Limit | The number of concurrent registrations allowed on this zone. The default is unlimited. | | Hpc Oversubscription | This parameter specifies the amount of resource over-subscription (as a percentage) allowed for HPC calls. When the baseline call limit and bandwidth limit are reached, normal calls are not admitted, but additional HPC calls are allowed up to the configured percentage value.
