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>
Daniel<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>
