The Siemens Gigaset C620A Trio: Family friendly cordless phones with nuisance call blocking and answer machine

Gigaset C620A Reddot Design AwardGigaset delivers a blend of outstanding sound quality, intuitive features, and stylish design with their C620A. Offering innovative call blocking facility to put an end to unwanted disturbances and bring peace back into the home, the C620A also facilitates calls in crystal clear clarity thanks to HSP technology. The perfect choice for any home looking for top-quality in a set of cordless landline; the C620A is expandable up to six handsets.

Impressive features

The Gigaset C620A has been designed to meet the demands of day-to-day calling with a range of intuitive features. Boasting a larger battery capacity, the C620A delivers a remarkable talk-time of up to 26 hours; and there’s no need to worry if the phone rings and you’ve forgotten to charge with a standby time, which lasts for up to 530 hours. Call management is made easy, with a phonebook memory for up to 250 contacts (with space for up to 3 numbers per entry), as well as the blacklist function that can block up to 15 numbers from ringing. Further benefits include the time-controlled call silencing for when you want some peace and quiet; as well as the facility to double-up as a baby monitor.

Gigaset C620A with Answering Machine

Manage missed calls

The integrated answering machine on the base of the C620A reliably takes calls when you’re not available, and has a recording time for up to 55 minutes of messages. An illuminated icon on clear 1.8” display alerts you to missed calls that have not been checked; and you can even set up the C620A to divert your calls to another number or notify you by text whenever there is a new missed call or message helping you to keep in touch.
