How to use credit card machines over VoIP?

LolaBelle

One of my friends installed a VoIP system in her small business after AT&T increased her phone service rate by 300%. However, she is having problems getting her credit card machine to work with it; She consistently gets an error when it tries to send. Will credit card machines simply not work with VoIP systems, or is there something she can do to get it to function?

VOIP + Credit Card Terminal = Bad Idea

"Do not connect your dial-up credit card terminal to a VOIP connection!

Even if you get this to properly work, which is apparently possible using an analog adapter, you are now violating a number of PCI regulations regarding data security. When you process using a dial-up connection, the data transmission is not encrypted. Since the transaction is going over a phone network which operates differently, with regards to security, than internet, it’s OK by PCI and issuer data security standards (Whether the existing security is enough, is another debate). When you put that terminal on a VOIP connection, you are now transmitting unencrypted data directly over the internet.

Many credit card machines use an “old school” modem to connect, and I don’t know of a way to get them to work with VoIP. Maybe there is a way, but I don’t know it. She may have to buy another machine that is designed to work over an ethernet connection.
