CHAPTER 18
VoIP
18.1 Overview
Use this chapter to:
• Connect an analog phone to the Device.
• Make phone calls over the Internet, as well as the regular phone network.
• Configure settings such as speed dial.
• Configure network settings to optimize the voice quality of your phone calls.
18.1.1 What You Can Do in this Chapter
These screens allow you to configure your Device to make phone calls over the Internet and your
regular phone line, and to set up the phones you connect to the Device.
•Use the SIP Service Provider screen to configure the SIP server information, QoS for VoIP
calls, the numbers for certain phone functions (Section 18.3 on page 188).
•Use the SIP Account screen to set up information about your SIP account, control which SIP
accounts the phones connected to the Device use and configure audio settings such as volume
levels for the phones connected to the ZyXEL Device (Section 18.3 on page 188).
•Use the Phone Device screen to control which SIP accounts the phones connected to the Device
use (Section 18.5 on page 192).
•Use the Call Rule screen to set up shortcuts for dialing frequently-used (VoIP) phone numbers
(Section 18.6 on page 193).
You don’t 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.
