Asterisk Git-master version from April 8, 2026 (today)
Devices could not re-auth when they timed out. They showed as ‘State: UNAVAILABLE’. Outside registrations still worked. A ‘core stop gracefully’ on the CLI did not stop Asterisk. Neither did ‘core stop now’. I then re-booted the server, re-started Asterisk and everything worked again.
As well as configuration details. For example a change to res_pjsip_config_wizard to fix a deadlock went in, and the backtrace would show if that was the cause.
