Question about Gigaset Box 200A

I cannot directly confirm the compatibility of the base with answering machine with CL660HX handsets without checking the exact specification of the base. However, CL660HX handsets are generally compatible with CAT-iq 2.0/2.1 DECT bases. For accurate confirmation, we recommend checking compatibility on the official Gigaset website by selecting the base station and handset in question.
