Request – sending a call-card number?

Using an calling card on spv to work with Orange!! My old T68i had a calling card feature in which you could presend a 0800 freephone number before sending the tones of a number in your telephone book. This is so that you can call numbers very cheaply through other carriers eg onetel….2pence/min..etc.

With the T68 you would find the contact number, and by keeping your finger pressed on the send key, it would predial the freephone number first, then at connection, by pressing send, it would send the contact tones followed by a # or a *

Are there any clever programmers out there that can write some code to duplicate the Ericsson feature?
