● 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

usingeither:
■ NTPTimeserver2.android.pool.ntp.org
■ DHCP Option 42 (NTP).IfDHCPOption42(NTP)isoptedfor,thenetworkadministrator
