<p class="MsoNormal">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.<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">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.<o:p></o:p></p>

<div>
<p class="MsoNormal">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.<o:p></o:p></p>
