Adaptive NHT Configuration

You configure the SIP interface to set the state of this feature and to define the increments of time the Oracle® Enterprise Session Border Controller uses to perform adaptive HNT. Remember that the Oracle® Enterprise Session Border Controller uses the time you specify as the NAT interval, the supported time interval, as the basis on which to begin testing.

To configure adaptive HNT:

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

   ORACLE# configure terminal

2. Type session-router and press Enter to access the session-router path.

   ORACLE(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.

   ORACLE(session-router)# sip-interface

4. sip-dynamic-hnt—Enable this parameter if you want to use adaptive HNT. The default value is disabled. The valid values are:

   • enabled | disabled

5. max-nat-interval—Set the amount of time in seconds that testing should not exceed. The Oracle® Enterprise Session Border Controller will keep the expires interval at this value. The default value is 3600. The valid range is:

   • Minimum—0

   • Maximum—999999999

6. nat-int-increment—Set the amount of time in seconds to use as the increment in value in the SIP expires header. The default value is 10. The valid range is:

   • Minimum—0

   • Maximum—999999999

7. nat-test-increment—Set the amount of time in seconds that will be added to the test timer. The default value is 30. The valid range is:

   • Minimum—0

   • Maximum—999999999
