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

[Stephen Welsh]

Hi Anthony,

Its not well documented, but I believe there is (was) a developer level capability to access the AUX port. From memory I think this product used to use the AUX port:

I’m with the DevNet team at Cisco Live next week, I can ask around if you like, have you got a cool trick you want to use it for ;)

Kind Regards.

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?
