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

Hi All,
   As I know, if session timer of request is less than server's Min-SE, the server will reply with its Min-SE, but the following packet confuse me, anyone can show me why?
