  2. Accomplish the steps listed in Configuring SBC for External PSX page.

  3. Configure external PSX as remote server using the management IP address of the external PSX:

  4. Configure the PSX for a basic SIP call to include the following (refer to the PSX Provisioning Guide under PSX Documentation for details):

    1. Create the Gateway entry for the SBC using the system name.
