Hi,
I have VVX 601 phones running UC software version 6.2.0.3937 RTS80.
They are provisioned with these settings regarding NTP:
tcpIpApp.sntp.gmtOffset="3600"
tcpIpApp.sntp.gmtOffsetcityID="54"
tcpIpApp.sntp.resyncPeriod="900"
The phones are used in Germany, the city ID 54 stands for Berlin according to the manual and I thought this should be enough to correctly configure the time zone.
The phones now switched to DST time, they now have UTC+2. This would be correct for the US, but in Germany DST only begins at the end of March, so the correct time would be UTC+1 now.
What am I doing wrong?
I do not want to manually configure when DST is activated or deactivated (as with "tcpIpApp.sntp.daylightSavings.start" and so on), I want the phones to get this info from their internal timezone database. How can I do that?
Thanks.
Kind regards,
Gerd

Ok, after a bit of fiddling around and reading between the lines of the admin guide I found the solution:
You have to set
tcpIpApp.sntp.daylightSavings.enable="0"
to have the phone activate DST according to the rules defined by gmtOffsetcityID.
Setting enable=0 to enable something seems counterintuitive to me, especially if the documentation in the admin guide says "Enable or disable Daylight Savings Time rules to the displayed time".
I think what is actually meant is "Enable to override the Daylight Savings Time rules of the timezone set by tcpIpApp.sntp.gmtOffsetcityID with the options set in tcpIpApp.sntp.daylightSavings".
It would be nice if you could forward this as improvement to your documentation department.
Thanks.
