I read any posts in this forum, but, not is clear for me if this problem is related any bug or no. Any have idea about this?
Thanks for your contact. The timezone current is 2012j and it putted in march (previously 2012c), because, the IP Phone 7911 statyed 1 hour ahead after finish the DST in GMT-3 America/São Paulo. When we had the problem, putted the version 2012j and solved the problem, but, in this version not is informed that should to affect the model specific. The IP Phone 7940/7960 are many old and my suspect is about firmware version. Am I sure in my affirmation?
I read the 03 last updates about DST and nothing each speak about Brasil GMT-3 America/Sao Paulo
