Configuring the Answer Detector Feature

The device's Answer Detect (AD) feature detects voice activity in a call. The AD feature detects the following events:

Speech - speech is detected.
End of speech - silence (no speech) for the configured duration (see below) is detected.
To configure AD:
1. Open the DSP Settings page (Setup menu > Signaling & Media tab > Media folder > DSP Settings).
2. Scroll down to the Answer Detector group:

3. Select the 'Enable Answer Detector' check box to enable the feature.
4. In the 'Answer Detector Activity Delay' field, enter the time (in 100-msec resolution) between when the device activates the Answer Detector feature and when it actually starts to detect. This delay may increase the device’s immunity to noises and non-speech signals at the beginning of a conversation.
5. In the 'Answer Detector Silence Time' field, enter the silence duration from when no speech input is detected until the device reports an End Of Speech event.
6. From the 'Answer Detector Redirection' drop-down list, select if the Answer Detector is applied to the IP network side (Yes) instead of the PSTN side (No).
7. In the 'Answer Detector Sensitivity' field, enter the Answer Detector's sensitivity, where 0 is the highest and 7 the lowest.
8. Click Apply.
