After rebooting my FreePBX server (due to a power failure or “sudo shutdown -r now”), incoming calls from a SIP trunk to a ring group containing some extensions don’t work. These calls go directly to the configured voice mail. The extensions show as Registered and I can make outgoing calls from them, but incoming calls don’t work. I have to do “fwconsole reload” for incoming calls to start working. After that, it’s fine until the next reboot. Any idea why this is happening?
