But anyways it's very obvious that the issue is something specific to TURN and not Opensips:

It probably has something to do with the combination of client/server/configuration, but not the SIP Server.<br>

<div dir="ltr">The screenshot doesn't show all the processes but I know it is hundreds because it's necessary to run 'killall' or similar command several times to get rid of all the processes and I can see the PIDs change each time.
<div><br>
</div>
<div>I think it absolutely can be OpenSIPS server causing the TURN error because OpenSIPS is in charge of creating the sessions in the first place, and if there are hundreds of OpenSIPS processes running then there will be hundreds of sessions created for each
call.</div>

<br>
Also the Opensips server should not have any connection/relation to your TURN Server, so i don't think Opensips could be the issue.<br>
<br>
A quick google search for "TURN <span>437 Allocation Mismatch</span>" suggests that it's a TURN CLIENT <--> TURN Server problem.
<span>It could be related to the TURN client implementation.</span><br>
