All ip phones 7911 and 7970 models show the wrong time. We are on GMT - 3 (BrasÃlia) and the models 7912 and 7940 are correct. We are on Dayligt savings time on Brazil (start : second sunday october to last sunday february 2008)
I have the firmware versions:
7911 - SCCP11.8-2-2SR1S
7970 - SCCP70.8-2-2SR1S
Os Service Release 2000.4.4.sr2
Callmanager System version:4.2(3)sr2b
Callmanager Administration version:4.2(2)
Callmanager Isstallation Id version:4.2(3)sr2b
I use the workaround changing manually the time clock from the server Callmanager, cause the option "automatically adjust clock for daylight summer" don't work.
I Can't show the correct time on phones ip communicator, 7911 and 7970. Help me!!
