VoIP is not supported
13.1 Overview
Use this chapter to:
Connect an analog phone to the LTE 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.
13.1.1 What You Need to Know
The following terms and concepts may help as you read this chapter.
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).
SIP
SIP stands for Session Initiation Protocol. SIP is a signaling standard that lets one network
device (like a computer or the LTE Device) send messages to another. In VoIP, these messages
are about phone calls over the network. For example, when you dial a number on your LTE

Device, it sends a SIP message over the network asking the other device (the number you dialed)
to take part in the call.
SIP Accounts
A SIP account is a type of VoIP account. It is an arrangement with a service provider that lets
you make phone calls over the Internet. When you set the LTE Device to use your SIP account
to make calls, the LTE Device is able to send all the information about the phone call to your
service provider on the Internet.
Strictly speaking, you don't need a SIP account. It is possible for one SIP device (like the LTE
Device) to call another without involving a SIP service provider. However, the networking
difficulties involved in doing this make it impractical under normal circumstances. Your SIP
account provider removes these difficulties by taking care of the call routing and setup -
figuring out how to get your call to the right place in a way that you and the other person can
talk to one another.
Voice Activity Detection/Silence Suppression
Voice Activity Detection (VAD) detects whether or not speech is present. This lets the LTE
Device reduce the bandwidth that a call uses by not transmitting "silent packets" when you are
not speaking.
Comfort Noise Generation
When using VAD, the LTE Device generates comfort noise when the other party is not speaking.
The comfort noise lets you know that the line is still connected as total silence could easily be
mistaken for a lost connection.
Echo Cancellation
G.168 is an ITU-T standard for eliminating the echo caused by the sound of your voice
reverberating in the telephone receiver while you talk.
Use this screen to maintain basic information about each SIP account. You can also enable and
disable each SIP account, configure the volume, echo cancellation and VAD (Voice Activity
Detection) settings for each individual phone port on the LTE Device.
How to Find Out More
See Section 16.6 for advanced technical information on SIP.
13.1.2 Before You Begin
Before you can use these screens, you need to have a VoIP account already set up. If you
don't have one yet, you can sign up with a VoIP service provider over the Internet.
You should have the information your VoIP service provider gave you ready, before you
start to configure the LTE Device.
