Session Manager Mapping

The ESBC supports mapping between multiple session managers and multiple ESBCs. Such mapping allows the ESBC to work in a redundant network configuration where you can map:
  • The primary session manager to the primary ESBC IP address
  • One or more redundant session managers to one or more redundant ESBCs

To map a redundant session manager to a redundant ESBC, map the private IP address of the redundant session manager to the public SIP IP address configured in public subelement of the http-alg element.

If the ESBC is behind a NAT, you can use the nat-address parameter in the public-interface parameter of your session-manager-mapping subelement. If you have not configured this parameter, ESBC can fall back to the nat-ip-address parameter of the http-alg-public sub-element.
