A telephone using conventional telephone mechanical and electrical components mounted within a telephone housing, typically mounted on a wall, with the earpiece and mouthpiece mounted within the telephone. To operate, the user pushes an on/off switch, dials his number, and then places his ear next to the fixed earpiece. The telephone is designed for use in prisons so inmates within a prison can not hang themselves with a handset cord or break a handset and handset cord off for use as a weapon. The telephone is also designed for use in any high crime or remote area to reduce the potential for vandalism. The telephone design reduces the cost of maintenance by eliminating the need to fix and replace a telephone handset.
