I have been trying to debug a SIP deadlock issue ( <a href="https://issues.asterisk.org/view.php?id=18403" target="_blank">https://issues.asterisk.org/view.php?id=18403</a>
) and can't seem to find it. I can reproduce this deadlock EVERY time
using three physical phones, and initiating a blind transfer that uses
REFER. The result is Asterisk stops processing all SIP requests until
killed and restarted. I have uploaded "core show channels" and a thread
backtrace per the debugging guidelines, and I am seeking any help in
resolving this issue. Thanks in advance for any suggestions!<br><br>-Jonathan<br><br>
