Our Prison Inmate Telephones were designed in conjunction with a major North American Justice System to provide reliable and cost effective communications for persons either charged or serving time. The rugged nature of these units reduces overall costs to the Correctional Facilities as they are not constantly repairing or replacing these telephones in hostile environments.

Safety was a main factor in the design of these units as the standard hand set length was reduced to 16” to lessen the chance of the hand set being used as a club or choking device. Guardian's vandal resistant equipment is designed to endure public abuse and tampering as well as low or high temperatures, dust, water and corrosion.
