You can use the TELETASK OPUS touch screen as a multi-functional home automation touch screen and now a hands-free intercom function has been added. Any OPUS device can make an internal call to any other OPUS and SIP phone. This may also be an external mobile phone.
In addition to a normal Intercom call, you can also make a group call (e.g., if you do not know the location of the person you are looking for in the house/building). If desired, you can also make a group call with AUTO ANSWER functionality.
E.g., in a home: 'hello everyone, dinner is ready' or 'hello kids, five minutes before we leave for school). E.g., in a business environment: 'hello John, your taxi has arrived' or 'Patrick, please call Els'.
