<font face="monospace">Hi Callum,<br>
<br>
The error logs translates into "not able to get a full SIP message
within 4 read operations from the network". What is puzzling is
the fact you claim that the REGISTER is actually successfully read
and processed by OpenSIPS - if this is correct, maybe there is
some other data on the connection, something else than the SIP
packages, maybe some CRLF pinging that triggers this.<br>
Do you have pcap on that connection ?<br>
<br>
Best regards,<br>

<div dir="ltr">Hi All,<br>
<div><br>
</div>
<div>I'm wondering if anyone in the community has encountered
the iOS 15 WebRTC bug as reported here:</div>
<div><br>

</div>
<div><br>
</div>
<div>The bug causes INVITES to fail to be digested by opensips
with a log message as shown below:</div>
<div><br>
</div>
<div>opensips[217976]: ERROR:proto_<a class="moz-txt-link-freetext" href="wss:ws_process">wss:ws_process</a>: Made 4 read
attempts but message is not complete yet - closing connection<br>
</div>
<div><br>
</div>
<div>Worth noting is that REGISTER messages still arrive so as
mentioned in the article is does appear related to
fragmentation of the messages being sent through, perhaps
failing to conclude this for reassembly but I can't make sense
of the network trace.</div>
<div><br>
</div>
<div>My client device is using SIP.js and I can confirm that it
continues to work on Android and other iOS versions. I'm
currently running opensips 3.0.5 and would happily upgrade to
the latest version if there was anything worth trying or
wolfssl has any potential to resolve this issue!</div>
<div><br>
</div>
<div>Thanks,</div>
