I have the Archer VR600v and use the internal DECT station to connect my phones (Siemens Gigaset S68H and T-COM Sinus 301, both are about 10 years old). Calling and receiving calls wotks fine. CLIP (display of the callers phone number) also works. But I am not able to access other options of my Archer: List of missed calls and the answering machine are not available.

I guess this is due to some missing standard of my phones, most propably CAT-iq 2.0. Is this correct? And would I be able to use this functions with a DECT phone with CAT-iq 2.0?

I found some newer Gigasets (HX-series, C430HX or C570HX) have this option, has anyone experience with them?

Regards,
