25.1 Voice 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.

25.1.1 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 phone 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, and the numbers for
certain phone functions
• Use the SIP TLS Common screen to change the default TLS local port if you need to, and select a local
certificate for the SIP server to verify the Zyxel
• Use the Phone screens to change settings that depend on which region of the world the Zyxel Device
is in (Section 25.6 on page
• Use the Call Rule screen to set up shortcuts for dialing frequently-used (VoIP) phone numbers
25.8 on page
• Use the Call History screen to view a call history list
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.

25.1.2 What You Need to Know About VoIP

VoIP
VoIP stands for Voice over IP. IP is the Internet Protocol, which is the message-carrying standard the
Internet runs on. So, Voice over IP is the sending of voice signals (speech) over the Internet (or another
network that uses the Internet Protocol).
