Add a Local Response Map

Configuring cause and reason mapping for SIP to SIP calls requires a local response map. The entries in the map generate the SIP response and Q850 cause code value for particular error scenarios.

• If you plan to add a Reason header, enable the function in the global SIP configuration.

You can customize the SIP status SIP reason for a local error. For example, the default 503 message for the error that the Oracle® Enterprise Session Border Controller (E-SBC) sends when the licensed session capacity is reached is "503 licensed session capacity reached". You can customize the number for this error message in the SIP Status field, and you can customize the reason in the SIP Reason field. Select licensed-session-capacity-reached from the Local Error list and you can add custom text about the error to the SIP header.

.

Repeat the following procedure to create as many local response map entries as you need.

1. Access the entries configuration element.

   ORACLE# configure terminal
   ORACLE(configure)# session-router
   ORACLE(session-router)# local-response-map
   ORACLE(local-response-map)# local-response-map-entries
   ORACLE(local-response-map-entries)#

2. In the Local response map entries configuration, do the following.

   Attributes	Instructions
   Local error	Select a local error condition from the drop-down list to trigger this map.
   SIP status	Enter a SIP response code. Range: 100-699.
   Q850 cause	Enter a Q850 cause code. Range: 0-2147483647.
   SIP reason	Enter a SIP response comment in quotation marks.
   Q850 reason	Enter a Q850 cause comment in quotation marks.
   Method	Select a SIP failure response message from the drop-down list to map to a 200 OK. To deactivate this function, make no selection.
   Register response expires	Enter the number of seconds after which the REGISTER response expires. Range: 0-999999999.

3. Save the configuration.
