CHAPTER 4 Teams Application C455HD | Users & Administrator's Manual [Recommended] I f the DHCP server offers Timezone Options (100/101), the phone will set ■ the obtained time zone and display the correct time on the screen; the time will be calculated based on an embedded Time Zone database, factoring in DST. If the DHCP server offers Time Offset Option only (2), the phone will assign the obtained ■ time offset to the first matched region in the list but there is a good chance it won’t reflect the actual geographical location, therefore the displayed time might be incorrect in some cases. For example, if the given time offset is GMT-5 and the phone is located in Mexico, the phone will get the time (and the DST setting) from central time and not from Mexico because in GMT-5 there is also Central Daylight Time. The network administrator must make sure the phone can access the following URLs (to check connectivity with the internet): https://www.google.com/generate_204 http://connectivitycheck.gstatic.com/generate_204 http://www.google.com/gen_204 If the internet connectivity check fails, a ‘No Internet Access’ warning pops up on the phone screen. Figure 4-1: Internet Connectivity Check - No Internet Access This can point to a problem that is preventing the phone from fully functioning in a Teams environment.
