Important Notes

Note the following:

  • The endpoint to which the response is being sent must be a trusted endpoint. The option disable-ppi-to-pai should not be configured in the global SIP configuration’s options list.
  • If the P-Preferred-Identity header is present in the response, the Oracle Communications Unified Session Manager will delete the header.
  • If the P-Asserted-Identity header is present in the response, the Oracle Communications Unified Session Manager will overwrite that -Asserted-Identity.
