Signing In

Before using the phone (after setting it up), you need to sign in for security purposes. You can sign-in with user credentials locally on your IP phone, or remotely with your PC / smart phone.

‘Modern Authentication’ is also supported.

Before signing in, the network administrator must make sure the phone gets the local time, using either:

■

DHCP Option 42 (NTP). If DHCP Option 42 (NTP) is opted for, the network administrator must specify the server providing NTP for the network.

■

time.android.com. NTP server option for Android phones.

■

time.windows.com. The phones’ default NTP server is sometimes not configured in DHCP Option 42. If not, the phones will attempt the Google NTP server. If DHCP Option 42 is not configured and the Google NTP server is blocked (for example), the phones will use this server and if it’s unavailable, the server time.nist.gov, described next.

■

time.nist.gov. The phones’ default NTP server is sometimes not configured in DHCP Option 42. If not, the phones will attempt the Google NTP server. If DHCP Option 42 is not configured and the Google NTP server is blocked (for example), the phones will use this server (time.nist.gov) if the server time.windows.com described previously is unavailable.

■

Admins can manually define the NTP server to comply if necessary with enterprise security requirements, if those requirements preclude using DHCP Option 42.

Manual configuration takes precedence over DHCP Option 42 and the time servers.

Two ways to manually define the NTP server are available:

●

in the phone's user interface

●

in the phone’s .cfg configuration file, using parameter 'date_time/ntp/server_address'

In most regions, Daylight Saving Time changes the regional time twice a year. DST Validation allows maintaining accurate time. Two options for phones to get the correct time are:

■

[Recommended] If 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) and if the Timezone priority mechanism is determined to be on DHCP and not on GEOLOCATION, 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.

If the internet connectivity check fails, a ‘No Internet Access’ warning pops up on the phone screen.

Internet Connectivity Check - No Internet Access

This can point to a problem that is preventing the phone from fully functioning in a Teams environment. The user can ignore the message if the Teams application is fully functioning, or can report a problem if the Teams application is not fully functioning.
