OP
cheaper to get a virtual local landline number that goes direct to your mobile.
That sounds great but I cant take your advice as you are a compulsive liar
I had no idea that existed! Will definetly look into that as an alternative! Now all I need is a way to connect a corded phone to a mobile so that instead of using a mobile to talk I can use the system as a regular phone!
Also, the wire to the workshop: I am not sure what size it is and will check it out. Im sure that it is armoured but good suggestion.
