VoIP
22.1 Overview
You can make calls over the Internet using VoIP technology. For this, you first need to set up a SIP
account with a SIP service provider.
Use this chapter to:
• Connect an analog phone to the Zyxel Device.
• Configure settings such as speed dial.
• Configure network settings to optimize the voice quality of your phone calls.
22.1.1 What You Can Do in this Chapter
These screens allow you to configure your Zyxel Device to make phone calls over the Internet and your
regular phone line, and to set up the phones you connect to the Zyxel Device.
• Use the
SIP Account
screen (
) to set up information about your SIP account,
control which SIP accounts the phones connected to the Zyxel Device use and configure audio
settings such as volume levels for the phones connected to the Zyxel Device.
• Use the
SIP Service Provider
screen (
) to configure the SIP server information,
QoS for VoIP calls, the numbers for certain phone functions, and dialing plan.
• Use the
Phone Device
screen (
) to control which SIP account(s) each phone
uses to handle outgoing and incoming calls.
• Use the
Region
screen (
) to change settings that depend on the country you
are in.
• Use the
Call Rule
screen (
) to set up shortcuts for dialing frequently-used
(VoIP) phone numbers.
• Use the
Call History
) to view detailed information for each outgoing
call you made or each incoming call from someone calling you. You can also view the summary list of
received, dialed and missed calls.
You do not necessarily need to use all these screens to set up your account. In fact, if your service
provider did not supply information on a particular field in a screen, it is usually best to leave it at its
default setting.
