Enhanced Gateway with Analog Devices

4.15.3 Configuring Comfort Noise and Gain Control

The Microsoft Lync network provides high voice quality by implementing suppression of

typing noise during calls and improved generation of “comfort noise,” which reduces

hissing and smoothes over the discontinuous flow of audio packets. You may need to

configure the Enhanced gateway to match these voice quality features, by enabling silence

suppression, comfort noise generation, automatic gain control (AGC), and echo canceller

(enabled by default).

Note:

Silence suppression is configured per coder type, as described in

Step 10 (Section 4.10 on page 44).

 To configure voice quality:

1. Open the RTP/RTCP Settings page (Configuration tab > VoIP menu > Media >

RTP/RTCP Settings).

Figure 4-45: RTP/RTCP Settings Page

2. From the 'Enable RFC 3389 CN payload Type' drop-down list, select Enable.

3. From the 'Comfort Noise Generation Negotiation' drop-down list, select Enable to

enable comfort noise generation.

4. Click Submit.

5. Open the IPMedia Settings page (Configuration tab > VoIP menu > Media >

IPMedia Settings).
