The ERE (Embedded Route Engine) supports number translations based on host part (contains a fully-qualified domain name) of the SIP headers. IP addresses format is not supported for host-part lookup. It is always recommended to use the fully-qualified domain name. The SBC retrieves the destination domain from the various SIP headers and sends it to ERE as part of the policy request. The domain name look-up is case insensitive and partial matches are supported, while first priority is always for full match.

The supported destination domain SIP headers are:

  • INVITE Message, R-URI Header
  • INVITE Message, TO Header
  • 3XX Message, Contact Header
