As cell phone technology improves, 911 operators are answering fewer accidental calls made by mobile phone users. According to Duane Phillips, Director of Emergency Communications Center, Metro-Nashville's Emergency Communications Center receives around 1,000 calls per day. In addition to the heavy volume of incoming calls, operators also answer calls that are not emergencies. "We still have to make about a half a million calls a year outgoing, where we are calling back where people are hanging up on a 911 call," Phillips explained. Officials told Nashville's News 2 several years ago it was easier for cell phone users to call 911 by accident especially if they kept their device in their pocket or purse. Phillips said flip phones and smart phones have helped reduce the number of unintentional calls made by cell phone users. Operators remind people if you call 911 by accident it is important to stay on the line to let the operator know you made a mistake and will not send out an emergency crew unnecessarily.
