Thanks for resp. However, the option to block all out-going calls is not exactly what we are looking for. We still wish to be able to use the phone for dial-out. We wish to be able to decide (maybe maintain a programmable list) which mobile numbers can be dialled e.g. If the number is not on a "list" then the number cannot be called if it begins "085/086/087".
We presume that whilst the service provider can block all out-going calls or block some numbers, they would not provide the ability to flex the "list", so we assume the need for a programmable phone or device that sits between the phone and the line?
