Yes. It's disabled by default, has issues, has warnings, and due to subsequent changes doesn't need to be set for reasonable usage.

The backtrace doesn't seem to be completely usable. Can you ensure that Asterisk is built without optimizations and try again? As well please describe exactly what you are doing. I...

Is it possible to get a debug level Asterisk log?

This was a result of DPMA creating an endpoint in itself. We just released a new DPMA version on Monday that resolves this issue.

Unfortunately the backtraces don't show anything abnormal - it shows a normal running Asterisk. I suspect this needs fresh eyes with a fresh perspective, so I'll leave this in triage...

Frames are not always queued. File descriptors are also polled on, such as for network traffic like RTP, and without a thread polling and reading then the network queue will...

I'm not that familiar with autoservice, so not really sure. The not sleeping if ast_autoservice_stop is called within such a thread does seem reasonable though.

To have it reload without requiring allow_reload the filenames MUST be the same, PJSIP doesn't support changing the filenames. I just tested changing the underlying files (using the same names)...

What actually shows on the Asterisk console when it attempts to play it?
