Hi,
I have problem with phone time, I have CME (c2800nm-adventerprisek9-mz.151-4.M5.bin) and multiple phone types 6921, 7942 and 7945.
i dont have ntp, and i even dont have internet connection to CME (no time sync)
Phones 7945 and 7942 has correct time disply, but phone 6921 shows differnet time.
I have seen alot on this subject on the forum, and i tried most of them, but still same issue. and i check the troubleshooting guide by cisco.
