There's another way of achieving the end result - a VOIP account with say Sipgate.co.uk - a UK geographic number (eg 01491 XXXXXX, you choose the area code) with voicemail that sends a .wav file to your nominated email account, and which you can listen to online from any internet enabled terminal.
Ideal if you are travelling, and can't take mobile calls because you are six miles high. Free to set up, and you only pay if you place outgoing calls over their network, no charge for incoming.
