3147 - Emergency Call Fallback

You can enable the rejection of priority calls per a configured SIP interface. When this option is enabled, the Oracle Communications Session Border Controller does not allow priority calls through that SIP interface, and the call is rejected with a 380 response.

If the send-380-response parameter in the SIP interface is configured, this string is provided as a reason in the 380 message. If this parameter is not populated, the default message priority calls not allowed is sent.

1. In Superuser mode, type configure terminal and press Enter.

   ACMEPACKET# configure terminal

   ACMEPACKET(configure)# session-router

3. Type sip-interface and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.

   ACMEPACKET(session-router)# sip-interface
   ACMEPACKET(sip-interface)#

4. options—Type disallow-priority-calls to send a 380 response to priority calls.

   ACMEPACKET(session-router)# options disallow-priority-calls
