How do you enable daylight saving time on all devices?
For U.S. Time Zones:
Note: For GXP2200 that doesn’t have a self-defined time zone option, please select the matching time zone from the list.
Example for Pacific Time Zone:
Because the U.S. is west of the Prime Meridian, it will use a “+” positive sign for the offset. The Pacific Standard Time (PST) offset from UTC is -8:00, so you will change this to PST+8. If you look at daylight saving time for PST, you will see that it transitions to Pacific Daylight Time (PDT) and goes one hour ahead (Fall Back, Spring Forward). The PDT offset is -7:00, so you will use PDT+7. Daylight saving time
Be sure to add a comma “,” before proceeding. The rest of the syntax is adding the dates when daylight saving time occurs. The first section is for when daylight saving time starts. The second section is for when daylight saving time ends. “M” stands for month, and “3” is March, so it’s the 3rd month of the year. The next number is the week number, which is “2” for the second week of the month. The final number, “0,” stands for Sunday. Sunday = 0, Monday = 1, Tuesday = 2, etc. Add another comma “,” to separate the start and end of daylight saving time. Daylight saving time starts with “M11,” which is November, followed by “1” (first week) and “0” (Sunday). If you look at daylight saving time in the U.S., you’ll see it starts on March 10th (3rd month, 2nd week, Sunday = M3.2.0) and ends on November 3rd (11th month, 1st week, Sunday = M11.1.0).
What is Provisioning, and how do I provision my Grandstream device?
Grandstream SIP devices can be configured through the Web User Interface and also via Configuration File using TFTP or HTTP/HTTPS download. All Grandstream SIP devices support a proprietary binary configuration file format via the web interface. New product families like GXP21xx/14xx/11xx, GXV31xx, HT50x, and GXW40xx also accept configuration files in XML format in addition to the older proprietary binary format.
What is TR-069, and do Grandstream devices support it?
TR-069 is a communication protocol that enables secure auto-configuration as well as other CPE management functions within a common framework between a Customer Premises Equipment (CPE) and an Auto Configuration Server (ACS). Grandstream devices support this protocol.
