[asterisk-users] [External] Asterisk 18.12.1 to 18.15.0 upgrade seems to have introduced a behavior where PJSIP is unable to send a response to OPTIONS (seems to resolve after anywhere a period of time)

[Dan Cropp]

Thank you Joshua.

I am going to dig some more. I can’t see anything in the logs to indicate any reason for why it’s suddenly able to send the OPTIONS response.  There are zero SIP packets from Kamailio between the one that fails to send and the one that succeeds.  Very strange.

If I can’t get it working, I will create an issue report.

On two VMs, we encounter a strange behavior when we upgrade from 18.12.1 to 18.15.0 (also tried 18.15.1 last night).
When we roll the VMs back to 18.12.1, we don’t see the behavior repeat.

We have a Kamailio VM front ending the asterisk.

It sends OPTIONS messages periodically.

After startup (and also after reloading configuration settings), we see periods where the response can’t be sent.
After a period of time, it suddenly starts working.

 I haven't seen this before, and haven't seen any other reports of it so far. The OPTIONS code itself hasn't changed between the two. There was a fix for a crash in send_stateful_response so adding log messages to the error cases is likely needed to see in particular which one is failing.


Ha, those changes haven't even landed yet. It's pretty much a thin wrapper over PJSIP stuff in 18.15.1. The PJSIP versions are also fairly close too.
