Quick answer reqd please... re BT call divert feature.

just about to add call divert to our house phone so I can pick up calls on my mobile when I am out.
Currently BT charge £3.30 per month for it, BUT..... is this the final charge to me or do I end up picking up the cost of the call as well?
It does not say this in their advert so I do not know if you get stung for the extra call.

 

Here you go mate.

The original caller pays for the connection from their phone to your landline - but you pay for the onwards cost from the landline to your mobile.
