How Do You Avoid False Three-way Call Detection?

The nature of three-way call detection systems sometimes produces the false detection of three-calls, which results in the disconnection of normal calls. Normal background noise or conversation can wrongly signal that a three-way call is in place, which causes a lot of frustration for inmates, their family and friends.

In order to reduce the incidence of false three-way call detection, a number of different systems have been implemented. A device can be installed on the phone of the called party that detects any breaks in the telephone line that could indicate a three-way call request. Any other noise in the conversation would not have an effect on three-way call detection.

Scidyn has developed a system that calibrates the phone line by noting line conditions when a phone call is first made. The conditions are examined over 18 different parameters to establish when a three-way call has been made or if a call is placed on hold.

In addition to these systems, there are other ways to avoid false three-way call detection. When making and receiving calls with inmates, one should avoid the following practices:

  • Using a speaker phone
  • Using a cordless phone that generates static or other noise when out of range
  • Accepting call waiting while on the phone with an inmate
  • Covering the receiver to eliminate background conversation or other noise
  • Coughing, shouting or yelling into the receiver
  • Picking up other extensions while on the phone with an inmate (if this can’t be avoided, the callers should start talking immediately after the extension is picked up)
  • Hesitating after answering the call (the conversation should start immediately)

Service providers themselves have abused the phenomenon of false three-way call detection for their own benefit. Working with staff at correctional institutions, they can increase revenue by randomly disconnecting genuine phone calls under the presence that they were wrongly identified as three-way calls. This forces the inmate to make the call again and pay for it as a separate phone call.
