<p>Hello,</p>
<p>are you using topos module?</p>
<p>If yes, can you try without it and see if there is any
difference?</p>
<p>Also, the sip trace you pasted in the previous message does not
have both incoming and outgoing sip messages -- having them is
useful for troubleshooting.</p>
<p>Cheers,<br>
Daniel<br>

<div>I recently built an SBC to integrate Kamailio with
MS Teams following Henning Westerholt blob post and
all the other awesome tips I was able to find here in
the list.</div>
<div><br>
</div>
<div>Everything is working great. The only missing
piece I would like some thoughts on is about why MS
Teams is not accepting the BYE sent from Kamailio. </div>
<div>It eventually replies with "504 Server Time-out"</div>
