Re: Cant us Voicemail on Incoming calls only.?
incoming calls is just that. you will probably find that she can't dial 150 from the line either to get through to customer services.
There are two was to block outbound calls.
Incoming only literally stops the telephone hardware from recognising key presses on the phone. its an on/off switch only, nothing more.
The other option is call barring. Again this can be set to stop all chargeable calls from being dialled (which is why most people have incoming calls only).
However, this CAN recognise what keys are pressed on the phone (which is why it doesnt cut it straight away when dialling numbers, it waits to see if you are dialling 0800 for instance, which it would allow, compared with 0870, which it would block)
