SP Telephone Systems

The energy required for communication comes only from the user's voice. Acoustic energy is converted to electrical energy, and then from electrical energy to acoustic energy. All our voice-activated phones are made of a polymer alloy that provides excellent chemical resistance, high impact resistance, fire resistance and UV resistance. Such phones are used in cases where security is important during communication, for example, in combat systems on warships. Our voice-activated phone systems are MIL-STD compliant.
