[cisco-voip] IP Phone 7841 AUX Port and Credit Card Machine

Were psychedelic implements involved? I’d have to guess the credit card machine is also Ethernet or wireless and the user just didn’t know…
The aux port is only ever for headset peripherals in my understanding.

All,

I just ran into something very strange, were a customer is stating they are able to use a credit card machine via the AUX port on the back of a 7841.

The 7841 data sheet and admin guide would suggest that this is not possible, as their only reference to this port is with the use of a headset.

Now, I know these ports can be used for troubleshooting and/or hacking the phones, but I have not heard of a legit use like this before.

Can anyone comment on this?
