ABSTRACT:
Emergency call system which enables an individual to summon assistance includes an emergency call unit connectable to a telephone line, at least one remote speakerphone unit having a speakerphone and connectable to the same telephone line as the emergency call unit, and at least one pendant adapted to be worn by the individual and including a button. The emergency call unit is arranged to determine whether any remote speakerphone units are off-hook when the button on the pendant is actuated and if so, send a signal to each remote speakerphone unit to disconnect from the telephone line. If one of the remote speakerphone units is off-hook, it will not interfere with the functioning of the emergency call unit. The emergency call unit is also arranged to dial a predetermined emergency telephone number when the button on the pendant is actuated and the telephone line is available for an outbound call.
