Looking at BBC Local Radio - In my case Sussex and Surrey they have an 0845 Number!
It does beg the question if they can do it Nationally - Radio 1 being an example and I believe Radio 3 - 03700 numbers, why can't they just do it locally as well ?
The former "Southern Counties Radio" is a very interesting case, as the now two separate channels share many broadcasts.
Surrey has a 03700 number, Sussex has retained its 0845. For phone-ins, it depends which studio the broadcast is coming from.
On the general question, the decisions are made locally, although a national directive could be issued. The original plan was to use 0870 for national services and 0845 for local, which when we all had BT landlines (if ever) was a good policy. For local stations which spanned more than 2 charging areas, listeners could all call at a local rate. For national stations, London callers had no advantage.
The above is now ancient history. All the 0870's have been dealt with, but many of the 0845s remain.
