Abstract

Embodiments of interruption-sound devices for producing an interruption sound signal in a telecommunications transmission signal comprising a signal generator circuit and a processor circuit, in accordance with the present invention. The interruption sound signals are input into the appropriate location of the telecommunications device such that the interruptee perceives characteristic sounds such as those encountered when a mobile phone is about to drop a call. As a result, the interruptee will place blame for call disconnection on the mobile-phone technology and not on the interruptor. The interruption-sound device is suitable for incorporated into an external interruption module, a landline phone, and a mobile phone.
