Teams Application
The following describes functions related to the phone’s Microsoft Teams application.
Signing In
Using TeamsIPPhonePolicy, network administrators can create the following users
who can then sign in to the phone:
●
UserSignin: All features are available, i.e., calls, meetings and voicemail
●
MeetingSignIn: Only meetings are available
●
Common Area Phone (CAP) users who can sign in to the device with a CAP
account (as a CAP user) using TeamsIPPhonePolicy as follows:
✔
CAP SignIn (SearchOnCommonAreaPhoneMode=Enabled): The user has
calling and searching capability
✔
CAP SignIn (SearchOnCommonAreaPhoneMode=Disabled): The user has
calling capability
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.
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), 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
