The VoIP Line Screens
11.1 Overview
The VoIP > Line 1 and VoIP > Line 2 screens allow you to configure the
volume, echo cancellation, VAD settings and custom tones for phone ports 1 and 2
which map to SIP accounts 1 and 2 (see
Chapter 10 on page 139 ). Since both the
Line 1 and Line 2 screens are quite similar, this section uses the VoIP > Line 1
screens to describe the fields.
11.1.1 What You Can Do in This Chapter
• The Phone screen ( Section 11.2 on page 156 ) lets you configure phone
settings.
• The Voice screen ( Section 11.3 on page 157 ) lets you configure voice settings.
• The Profile screen ( Section 11.4 on page 158 ) lets you configure which country
of the world the WiMAX Device is in.
11.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Voice Activity Detection/Silence Suppression/Comfort Noise
Voice Activity Detection (VAD) detects whether or not speech is present. This lets
the WiMAX Device reduce the bandwidth that a call uses by not transmitting
“silent packets” when you are not speaking.
