Does anyone know if it's possible to bar calls, eg mobile, 118118 etc? I have checked Tiscali site but it doesnt seem possible. Is there some other way to bar them as my kids use the numbers all the time, I say kids but they are 19 and 21!. Hope someone can help me.

Take control yourself - get a Phone Guard.

Thanx Heinz, I never heard of this gadget but seems to be the answer to my prayers.
