I would like to replace a Gigaset SL400 with a Panasonic KX-TPA50. Both phones are DECT. Since DECT is a standard, does that mean the new phone should just work with my current base station?
DECT 6.0 is a standard, but many vendors' implementations are proprietary.
DECT 6.0 products do not support "GAP"; therefore, phones of differing brands are not guaranteed to work together. For example, a GE 28105EE1 DECT 6.0 headset will not receive calls if registered to a Uniden base unit.
Also, the Panasonic model is a SIP phone, and I see no mention of SIP in the specifications of the Gigaset model.
