We are now looking for a solution so that we have reliable programmable interface equipment for our calling card customer to connect to our gateway automatically without entering to their telephone handset (POTS) the gateway access number, account number and password.
By that way, our customer will only need to enter a destination number at their handset and the interface will dial automatically gateway access number. And after get connected it will send automatically the Account Number, Password and Destination Phone Number (the only number that entered by customer at their handset). We also want the interface to be able to work in analogue line gateway environment with high reliability.
We would grateful to receive the respond from you soon. Thank you.
