----------------------------------------------

             Summary: Support of mediasec SIP headers and SDP attributes
                 Key: ASTERISK-30032
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30032
             Project: Asterisk
          Issue Type: New Feature
      Security Level: None
          Components: Resources/res_pjsip
    Affects Versions: 18.11.0
            Reporter: Maximilian Fridrich


Some SIP UAs require the "mediasec" header field parameter in the SIP Security headers and the "3ge2ae" attribute in SDP to allow secure communication. These fields are not specified in any RFC but they are defined in the [3GPP specification 24.229|https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1055] (specifically sections 7.2A.7 and 6.1).

Some large telecommunication providers require these fields, so it would be desirable to make Asterisk compatible with them and/or switch them on through configuration options (in pjsip). There are patchsets out there that implement this behavior (to some extent) in res_pjsip (see mailing list).
