The SBC acting as a P-CSCF is configurable using the emergencyCallHandlingMode parameter to either accept or reject an emergency call based on local policy. If rejecting the call, the SBC sends UE a 380 (Alternative Service) response.
The CLI syntax to set the emergencyCallHandlingMode parameter is shown below:
% set addressContext <addressContextName> zone <ZONE_NAME> sipTrunkGroup <TG_NAME> services emergencyCallHandlingMode <none|rejectWith380>
...where:
- none = handle emergency calls
- rejectWith380 = reject emergency calls with a 380 responses
