Even though I'm fairly new to this game of trying to beat the system, surely there can only be ONE true way of getting all you can from telephone providers.

1) register with talktalk to get evening and weekend calls free.

2) register with 18866 for free daytime calls Mon-Fri 8am-6pm (1p connection charge for each call, irrespective of length of call.

3) when using 0845 or 0870 (high cost call numbers), drop 18866 and prefix 1270.

4) if international calls are made, use 1899 at 2p/3p connection and 1p per min.

It may seem like a bit of messing about, but you soon get used to it, alternatively an Orchid Router will dial the prefix for you. islandman
