Andreas Krüger commented on ASTERISK-27210:
-------------------------------------------

@Richard

The wiki just mentions the install_prereq script all over the guides, so I think people would think it is the "right" way to prepare the server before you compile Asterisk.
I do agree that the distros often backport the fixes, I'm simply just stating it is kinda misleading and the only thing we want to do is to be "up to date" and not be using old faulty versions of any library.
I did see the script got updated with libSRTP 2.0 but was just curious as the wiki stated it was yet not ready for production.
We are almost about to contribute with a complete production ready Asterisk running inside Docker, so this was simply just useful for us.

@Joshua
We will test PJSIP 2.7 when it is released within the 15 branch and then see if the issue is resolved.

> After investigating the circumstances during that timespan, i saw no behaviour out of the ordinary, and no changes has been made in the last months, and this has never occurred.
> Sadly, this is running in our production system, where we have debug turned off, so i can not provide a backtrace, but was just hoping maybe someone has seen similar before or can pinpoint us the the right direction for collecting more information so we can debug this further.
