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

             Summary: RTP performance issue with several channel drivers.
                 Key: ASTERISK-25296
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25296
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_skinny, Channels/chan_unistim, Core/RTP
    Affects Versions: 13.4.0
            Reporter: Richard Mudgett


The chan_skinny, chan_unistim, chan_rtp, and chan_ooh323 channel drivers don't negotiate RTP payload types.  (At least I couldn't find any negotiation for them.)  As a result they rely on Asterisk's default assignment of payload types.  Unfortunately, when RTP frames are read from these channels then an ao2 object is temporarily allocated and destroyed for each recieved frame by {{ast_rtp_codecs_get_payload()}}.  It is rather expensive to do so often.
