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

             Summary: switching between native_bridge and simple_bridge can cause one way audio
                 Key: ASTERISK-28284
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28284
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_rtp_asterisk
    Affects Versions: 13.25.0
            Reporter: Torrey Searle
         Attachments: issue.pcapng.gz

when there is a codec change, the smoother needs to be destroyed an recreated or else the smoother will discard the frames in the unexpected new format.

To decide if the smoother needs to replaced, res_rtp_asterisk looks at lasttxformat  

however p2p_write also updates lasttxformat but doesn't destroy the smoother causing a 1 way audio issue if returning to simple bridge afterwards

Attached is a pcap and logs that demonstrate the issue & a test that can somtimes reproduce the issue
