Debug log shows<br>that there is a 200 OK answer and SIP timeout at the same time. It<br>looks that while the SIP session was being destroyed due to timeout<br>call hangup due to answer event lead to race condition and channel<br>is being destroyed from two different places. The check ensures we<br>check it not to be NULL before freeing it.<br><br>ASTERISK-25371<br><br>Change-Id: I19f6566830640625e08f7b87bfe15758ad33a778<br>---<br>M channels/chan_pjsip.c<br>1 file changed, 19 insertions(+), 11 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.asterisk.org:29418/asterisk refs/changes/44/11444/2</pre><p>To view, visit <a href="https://gerrit.asterisk.org/c/asterisk/+/11444">change 11444</a>.
