    Hello,<br>
    <br>
    it appears that 100 trying is attempted to be sent after a 503 -- so
    the dialog doesn't exist because it was not initiated completely.
    Can you check the network sip traffic for such case?<br>
    <br>
    Cheers,<br>

        <div>Our current switch is being overloaded and when it does
          we're getting these 2 messages spammed in our logs:</div>

        <div>We're obviously working on not having the switch get so
          overloaded, but I'm also curious to understand why it can't
          find the dialogs. Is it a memory issue? Networking/dropping
          packets issue?</div>
        <div><br>
        </div>
        <div>I also imagine it's not as simple as a single overall
          answer either, but nevertheless I figured I'd reach out to the
          community and see if anyone has an understanding of what is
          happening and would be willing to take a few mins to explain.</div>

        <div>Thanks in advance,</div>
