             Summary: chan_iax jitterbuffer growing when time sources not in sync
                 Key: ASTERISK-28661
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28661
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_iax2
    Affects Versions: 16.4.0
            Reporter: Kirsty Tyerman


I have two asterisk servers, Server A and Server B. These two servers are peered via IAX. When I make a call between Server A and Server B I am experiencing poor audio quality and the jitter buffer on one end is continuously growing. 
Server A's time is approximatley 10 minutes behind Server B.
I have a PJSIP client registered to Server B call a PJSIP client registered to Server A. The call is established via IAX between Server A and Server B.
I have the IAX jitter buffers enabled on both Server A and Server B with trunktimestamps=yes.
When I establish the call, the "iax2 show channels" on Server A (date is behind) shows the "JitBuf" constantly growing. The max jitter buffer is 4000ms. It seems as though the jitter buffer is not handling the system clock being wrong when it should rely on the trunk timestamps that is relative to iax and disregard any system clocks.
