If you set up voxalot with the appropriate plan, it can be used for web call backs, call forwarding and possibly other features. You can also have multiple devices registered to your voxalot account and they can share the dial plan settings.
There is a place for local dial plans settings too, but these should be specific for the device and may be the difference between using VoIP or PSTN, such as a 000 call which should always route via the PSTN.
