Two main problems with this. First off, it's against Visa/Mastercard security regulations to transmit card numbers unencrypted over the internet, while the same is not true for sending them over the pstn. Secondly, your failure rate will probably be high. The protocols used for clearing credit cards over modems have quite a bit of back and forth communication for error checking. For the price of a single POTS line it's not worth it.
