<p>Hello,</p>
<p>so, checking in the code for that log messages, it appears that
min_se parameter has to be at least 90, you have 60:<br>
</p>
<p>modparam("sst", "min_se", 60)<br>
</p>
Can you change and see if works ok? If yes, then I will add some
checks in the code to detect the situation at start up.<br>
<br>
Somehow is also mentioned in a docs examples:<br>

<p>Hello,</p>
<p>can you pull again the latest master, re-compile and
install, then set debug=3 in kamailio cfg and test again?</p>
<p>I pushed a patch that should print a log message with the
values for session expire and min-se when rejecting with
422. I couldn't spot something wrong at a quick look at the
code, but the values could be wrong and I want to double
check.</p>
<p>You can send the relevant log messages from syslog once you
do the test with such an invite.</p>
<p>Cheers,<br>
