So asterisk doesn’t dial extension 300 because of DND / busy.
This database key/value cannot be deleted from CLI. Both database del DND 300 and database deltree DND are removing the dnd of other extensions but not this 300
core reload / core restart / fwconsole restart don’t help, this key/value still exists…
Have someone seen this before? Is there any other method to remove the extension’s dnd from the database?
TheAsterisk SQLite internal database got a little bit corrupted. This wasn’t visible in the logs or somewhere else - we only seen some strange behavior of DND (the last time the key /DND/300 had a value ‘RINGING’ instead of YES )
So we repaired the database (there are a lot of tutorials online - mostly recommend to dump the DB and import it again).
Don’t forget to change the owner/group of the sqlite database file to asterisk…
