First my english isn't not so good and i will try to do my best to express myself :P
Im looking for a solution that can do the next scenario
Mobile phone ---- dial -----> (i dont know the name of this hardware) ---- redirect call to mobile or land number using VOIP provider like the betamax ------>
Benefits: I have a contract that the call to the both ( mine and other sim ) at 0 cents and then voip has cheaper rates to other land/mobile numbers, my idea is to pay only the call from voip account.
And how its dial the number from machine?any code before the number or after...have no idea...
my knowledge in this area is -1 :D
