The CL660 Duo (CH version) from Gigaset does not have an internal answering machine. It is an analogue landline phone with hands-free function, but without integrated answering machine function.

The CL660A version, on the other hand, has a separate answering machine box (Box 200A) with up to 30 minutes of recording time, which can also be connected. The pure CL660 model does not offer this function internally.
