We are using CUCM 6.1. We have mostly 7961's and some 7941's, all using SCCP. I have the NTP References pointing to our PDC emulator and a backup. The PDC syncs to an external source. I have the date/time group configured to use both NTP Refernces, and all the phones are in that date/time group.
But I cannot get the phones to sync the time properly. I've done a reset, restart, etc. What else am I missing?
