Setting the Response Code Block

To enable the SIP HMR enhancements, you need to set an option in SIP interface configuration that keeps the Oracle® Enterprise Session Border Controller from sending the response you designate.

Note that this example sets the dropResponse option to 699, where 699 is an arbitrary code used to later match the HMR.

To enable SIP response blocking for a SIP interface:

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

   ORACLE# configure terminal

2. Type session-router and press Enter to access the signaling-level configuration elements.

   ORACLE(configure)# session-router
   ORACLE(session-router)#

3. Type sip-interface and press Enter.

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

   If you are adding support for this feature to a pre-existing SIP interface, then you must select (using the ACLI select command) the configuration that you want to edit.

4. options—Set the options parameter by typing options, a Space, the option name dropResponse with a plus sign in front of it, type the equal sign and the code(s) or range(s) you want blocked. If there is more than one, separate your entries with a colon. Then press Enter.

   ORACLE(sip-interface)# options +dropResponse=699

   If you type the option without the plus sign, you will overwrite any previously configured options. In order to append the new options to this configuration’s options list, you must prepend the new option with a plus sign as shown in the previous example.

5. Save and activate your configuration.
