  • P-Media-Authorization: a P-CSCF generated authorization token. This particular example shows a Policy-Element generated by "pdf1.home1.net" with credentials "9BV3072". "00" at the end of the authorization token is required to pad to a multiple of 4 bytes.
  • Record-Route: P-CSCF1 rewrites the Record-Route header to add the port number negotiated during the security agreement and the comp=sigcomp parameter to its own SIP URI.
