Armored Hotline Phone [HP-3500]

This is a great little phone for the price. The autodialer allows anyone to pick up the handset and 9-1-1 is automatically connected. Only draw back I found is the phone is shipped with audio settings at the LOWEST setting which is controlled by dip switches inside. This is not a problem to overcome, however there are no instructions with the phone to alert you to this adjustment. When first installed and tested, there was one way audio whereby the 911 operator could not hear me speak. After a quick call to Payphone.com tech suppert this was quickly corrected. Great emergency phone for the money and I will buy it again.
