[SR-Users] Session timer issue

[Daniel-Constantin Mierla]

Hello,

can you pull again the latest master, re-compile and install, then set
debug=3 in kamailio cfg and test again?

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.

You can send the relevant log messages from syslog once you do the test
with such an invite.

Cheers,
Daniel
