11. Why do I hear a dial tone even though I have not dialed an FXO number? The same happens on any VoIP number I dial.
In case of network failure or failure while registering to the VoIP server the outgoing calls will be routed to the first free FXO line if the Use
FXO as lifeline option is enabled on the System Setting > Call page.
