I don’t understand why the dial plan for your ring group is not being built.
Confirm that the database is correct – at a root shell type fwconsole mysql asterisk
then at the MariaDB prompt issue select * from ringgroups
Are you running the FreePBX Distro? If not, provide details.
In Admin->Module Admin, what versions do you see for FreePBX Framework, Core and Ring Groups?
I’m stumped. The database appears to be built correctly, but no ring groups got written to the dialplan.
I have no idea how that can be. Possibly, a module version inconsistency, or a system package vs. module inconsistency. Assuming that you have a good backup, try upgrading all modules (or at least those that seem relevant). Or, consider upgrading to FreePBX 15. See
What are you running this on? Running the Distro, something built from a script (which), or built on your own?
