The system validates emergency numbers before treating a call as an emergency. This ensures that only calls to verified emergency numbers are handled as emergency calls, allowing them to bypass standard restrictions such as suspended accounts, insufficient balances, and service limits. The validation is controlled by the EmergencyModule.Verify_Dialing_Rule_Policy option in the Configuration server web interface.
This option can have one of two values:
- trust – the system does not validate emergency numbers specified in a dialing rule.
- check – the system checks that an emergency number matches the EmergencyModule.Numbers or EmergencyModule.Pattern option.
If you install MR130 or a later version from scratch, the default value is check. This helps prevent end users from configuring unsupported emergency numbers when they are allowed to configure their own dialing rules.
To allow calls to any emergency number defined in the dialing rule without verification, set EmergencyModule.Verify_Dialing_Rule_Policy to trust.
Note: Before MR130, the default value of EmergencyModule.Verify_Dialing_Rule_Policy was trust. Installations updated to MR130 or a later release version will retain this default value. This can be changed to check manually.
