I'm thinking of setting up VoIP as I'm a home worker - allowing me a new number for business, etc, but I'd like to keep my normal phone line in use to keep my existing home number.

The thing that is putting me off is the #0 prefix to use the PSTN line. Is it possible to swap that so that the default is PSTN, and I have to dial #0 to dial out with VoIP? The rest of the family wouldn't appreciate having to dial a prefix to call out!

Enable Digit Map:

Match Prefix - 0
Mode - None
Mind Len - 0
Max Len - 25
Route - PSTN

If you're in London you might also want to add 8/7.
