The Handset Top Inmate Telephone features a short handset cord that exits through the top of the phone to reduce the risk of inmate hanging. It is the only phone of this type on the market that meets ADA requirements.

The Invisible Hookswitch was developed by TMG as a substitute to a standard Mechanical Hookswitch. It is an anti-fraud component that prevents flash hook dialing and vandalism. In addition, the Invisible Hookswitch seals the front of the phone to keep out unwanted moisture.
