3cx SMB Free 10 instance. 1 extension. 1 DID. Inbound and outbound calls work fine. Missed calls go to Voicemail for the extension. The extension is connected via FXS registered device. When dialing 999, or 9999 to access voicemail both fail. I get a no outbound rule error for dialing 9999, so I created a rule and then got voice prompt saying forbidden by administrator. Voicemail for the extension is enabled. How can we dial to access voicemail from the FXS device. User isnt using the softphone applications on any device.
