NMC Emergency Call Control

By configuring a Network Management Control (NMC), the Oracle Communications Unified Session Manager can flag a call for special priority early after it is received and validated by the system. The destination identifier must be configured in the NMC with the service URN of an incoming emergency call. Also, the NMC configuration must have its next hop parameter left blank. This lets the Oracle Communications Unified Session Manager route the emergency call with local policies.

For example, if urn:service:sos is the configured value in the NMC’s destination identifier, and an INVITE arrives on the Oracle Communications Unified Session Manager with urn:service:sos in the request URI, the call will be flagged for emergency handling. The next step in call processing is for the INVITE to be evaluated by local policy.
