<p>Indeed <code>track_cseq_updates</code> had to be set to <code>0</code>, forgot to update after copy&paste from readme (I updated my comment for future references).</p>
<p>My commit from yesterday was because I discovered that cseq update processing was done for dmq requests. It's useless, but I didn't get the time to dig in further if that can expose any issue.</p>
<p>I suggested to disable it because it was executed and it is not a common deployment, so I wanted to isolate if that was somehow leading to the deadlock</p>
