The 6 handsets included in the Gigaset C620A Duo + Gigaset A540H Trio ensure that you can be reached wherever you are in the house or the office. Calls aren't easy to miss, with the lit display and flashing ring button in addition to the ringtone. Still didn't get to the phone in time? No problem. The integrated answering machine records up to 55 minutes of messages, which can be listened to remotely with the handsets of the C620A. Both the base station and the individual handsets can be set to your personal preferences. You can easily assign specific ringtones to specific people for example, so that you'll know immediately who's calling you. The C620A Duo also has a baby monitor mode, as well as an energy-saving mode.
