Some telephones, depending on the brand and model, have the intercom function, which allows to begin communication by sending the signal. When the signal comes, the telephone set rings a signal different from the standard ring tone call. After that the telephone temporarily switches off from the telephone line and works as an intercom.
Our aim is to bring together a portfolio of communication tools for businesses and private individuals to enable them to operate more efficiently, reduce costs, and stay in touch with their customers, suppliers, friends and colleagues.
