Location of panasonic outlets

Are you asking where to buy Panasonic phones? Best Buy carries them. Office Max and Office Depot may. I don't think Staples does anymore.

But you should be able to go to Panasonic's site and find where to buy.

You didn't say System or not:
Panasonic Phone Systems - New Panasonic KXTA824 - KX-TDA Phone Systems - E System Sales, Inc. (http://www.panasonicphonesystems.com/)
