Session timer issue

sgy
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?

Re: Session timer issue

Daniel-Constantin Mierla-6

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

Re: Session timer issue

Daniel-Constantin Mierla-6

Hello,

so, checking in the code for that log messages, it appears that min_se parameter has to be at least 90, you have 60:

modparam("sst", "min_se", 60)

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.

Somehow is also mentioned in a docs examples:

  - https://kamailio.org/docs/modules/5.0.x/modules/sst.html#sst.f.sstCheckMin

Cheers,
Daniel

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?
