Internet Call Settings
You can make calls and receive calls over the Internet
when connected to a Wi-Fi network, rather than over your
mobile network.
To place a call over the Internet, your phone must be
congured to use an Internet calling account. After you
set up the account, placing an Internet call is not different
than placing any other call. However, you must be
connected to a Wi-Fi network. When you are making an
Internet call, the phone displays the Internet call near the
top of the screen.
SIP Accounts
Internet calling is based on the Session Initiation Protocol
(SIP) for voice calls on the Internet Protocol (IP) network.
To add a SIP account and congure your incoming and
outgoing preferences:
1. In the Call settings screen, select SIP Accounts.
2. Enable Receive incoming calls to answer incoming
Internet calls.
