FYI, this is a home phone network, no mobile carrier involved. Not sure why that came up. With Callcentric in the loop I've only seen two valid CNAM entries in my phone's call log with a whole lot of "No Data" or "Incomplete"; when that happened there wasn't even a number in the phone log. However, for every invalid entry in my phone's call log, there was a corresponding valid entry in the DirecTV log. Clearly the info is there so why doesn't my phone system see it? After taking Callcentric out (in GV settings, forward to Chat vs Callcentric) the 2 calls that came in showed just numbers in the phone log as expected. FYI, the phone is a Siemens 8825 Gigaset with 8 remote handsets; always worked with POTS.
