Hello,<br>
<br>
at first sight looks like a missing safety check, but I may be wrong
after a long day. I need to look a bit deeper at it.<br>
<br>
Did you stress test it or was just casual trying? You said it
happened one, couldn't be reproduced, right?<br>
<br>
Cheers,<br>
Daniel<br>

<div> Hello,<br>
<br>
could be related, but the issue seems to be while
processing a SIP reply, not with suspend/continue of a
request. Can you send the output of 'bt full'?<br>
<br>
Cheers,<br>
Daniel<br>
