Can you tell me how to use this feature? I've just installed an Obi200 and am hoping to avoid having to re-enter my google contacts manually into the old Panasonic cordless phone (KX-TG7642) that I've attached to the Obi200.
The (USA) caller ID system has two parts: the phone number (CID) and the calling party's name (CNAM). The phone number is sent by your service provider (e.g. Google Voice, Callcentric, voip.ms, etc.) with your outbound call. The calling party's name is not sent for calls that traverse the Public Switched Telephone Network (PSTN). Instead, the called party's (your) telephone service provider may (or may not) look up the name in a database of phone numbers matched to names. There is a cost to maintain these databases that service providers have to pay.
Google Voice doesn't pay to use CNAM, so it is not doing a look-up in the industry databases when somebody calls your Google Voice phone number. Google offers a partial solution: if the telephone number of the person calling you is in your Google Contacts, then Google Voice will match that name and number and display it on your telephone. If the calling number is a business that Google knows about, it will display that business' name. If neither of those things are available, then it will only display the numeric CID.
None of this has anything to do with the address book/contacts list stored locally on your cordless phone. If you want to store names and numbers there, you can certainly do that, too. Typically, whatever is stored locally on your telephone will override whatever is being sent from the telephone network.

I have noticed that on the Google Voice Calls page it is easy to add people to Contacts but not businesses. But not all business have names available. It would be nice to be able to add these easier.
Zopa:
Can Obi device lookup CNAM itself, prior to displaying incoming call from GV? Is there something inherently difficult in that setup?

Does "not possible" meet your definition of "inherently difficult".
Zopa:
It does, however if you could share the "why", it would be greatly appreciated. One would think, that it would be a somewhat trivial software modification to have Obi modify the CID info coming in.
