             Summary: add configuration setting to enable RTCP PLI, FIR and NACK independently from "webrtc" setting
                 Key: ASTERISK-30052
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30052
             Project: Asterisk
          Issue Type: Improvement
      Security Level: None
          Components: Resources/res_pjsip_sdp_rtp
    Affects Versions: 18.11.1
         Environment: Sangoma FreePBX 14 and higher on Sangoma OS7
            Reporter: Università di Bologna - CESIA VoIP
            Severity: Blocker


Asterisk's "webrtc" configuration setting in pjsip.conf enables several features required to correctly interface webrtc clients like:
+ dtls media
+ RTP MEDIA BUNDLE (RFC8843)
+ rtcp mux
+ avpf
+ ice
and particularly
+ RTP PLI, FIR, NACK, CCM (RFC5104 on AVPF)

In our application, webrtc is not exposed directly by Asterisk: for security reasons, we are deploying an external dedicated high-end commercial webrtc proxy that will be exposed on the internet.
To interoperate correctly on video streams our application needs RFC5104 enabled to support frame retransmission/resynchronization.
However, if we enable "webrtc" settings also the RFC8843 is automatically enabled: unfortunately, the webrtc proxy we are deploying does not support RFC8843 and does not work correctly.

We ask if you think would be possible to develop a little patch to read a new "use_rfc5104" setting which enables the required features (fir, nack, etc...) independently from the "webrtc" setting. In this way, we can enable FIR, NACK, etc... without the need to enable RTP MEDIA BUNDLE.
We tested positively this feature on our test environment and fully fix the issues.

What about if we make a merge request for this purpose?

Thank you in advance,

Camillo Toselli - Università di Bologna
