Your Inmate Telephone Experts

Creating Quality Connections Since 1991



Telcom Marketing Group, Inc. is the leading manufacturer of Coinless Inmate Telephones and Visitation Phones in the United States. We provide the highest quality product, with the features you need, at the lowest total cost.

Each product is engineered to minimize maintenance costs, while providing maximum security. Every phone TMG manufactures is rugged and vandal-resistant.

The Handset Top Inmate Telephone features a short handset cord that exits through the top of the phone to deter 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.


Whether for City or County jails, State or Federal prisons, halfway houses, adult or juvenile correctional facilities, TMG has a complete line up of products to cover any application.
