This should be an easy question, but a search of Cisco doesn't seem to pull up the answer.
The AUX port on the back of 7960 IP Phones isn't really mentioned in any of the 7960 documents. What is it actually used for?
What sort of implementation/setup would require or use the AUX port?
Is there any documentation on this?
I came across a few Analog Polycoms plugged into the AUX port today. I'm almost certain it was a mistake by the cabler, but still it got me thinking...
Thanks for your help!
7960 AUX port is commonly used for connecting Cisco 7914 Expansion Module.
Some info about other devices that could be connected to AUX port you can find in "Lantronix Application Extension SDK for Cisco IP Phones.doc" delivered in IP Phones Services SDK.
