Call Barring - Mobiles

Question

I have the Unlimited Anytime plan but wanted to bar calls to mobiles, but this isn't available as a stand alone option.  So my National calls that are inclusive of my plan are now also barred, why?????  Could the barring not be split down to national, international, mobiles and an all 3 option??? (International is available as a stand alone already!!) 
It's a real pain in the bottom because I now can't call family around the country!

Answer 1

If you're not paying for it then you don't have the type you can bar mobile calls.
BT have a thing call Admin Controlled Barring, it is free but only BT can turn it on and off. With this you can have;
1. International Calls Barred
2. Premium Rate Service Calls Barred
3. International & Premium Rate Service Calls Barred
I think there is an all calls barred option but can't remember.
To stop people calling mobiles you would have to rent Call Barring, when I worked for BT it was £2.50 a month, may have gone up since then. Thing with this barring is you can switch it on or off when you want and choose what you want to bar. You would be given a four digit pin number with it in order to take it off when, if you wanted to dial a mobile or international number.
