With DECT wireless units, there is always a base unit that is physically plugged in to the ATA. Pairing each of the extension handsets with the base unit shows the caller id yet still no caller id on the extensions. I have the latest FW on the OBI200 but the DECT units are about five years old so maybe off to Costco for an upgrade.
UPDATE: new clue.... if the caller has an entry in the handset already then the proper caller id shows on all of the extensions but if the caller is new (never called before) then nothing shows up. Maybe the OBI200 is sending a blank caller id for new callers.
No, not all DECT phone systems have a telephone in the base; I have a Panasonic model with no phone in the base.
There are two different types of caller ID: caller ID number, and caller ID name. The number is sent along with the call signaling by the calling party's service provider, to the called party's service provider. You should see the calling party's number on your handsets. Caller ID name (CNAM) is
not sent by the calling party's service provider. When the called party's telco receives the call at its switch, it looks up the number in a data base of numbers matched to names, and then sends it to the called party's equipment between the first and second rings. Google doesn't feed its users' names into those databases, nor does it subscribe to the data bases, so it doesn't look up any names.
As you found, you are merely seeing names stored locally on your telephone's address book.
