Automatic Bandwidth Amplification
Automatic Bandwidth Amplification
The automatic bandwidth amplification function is used to improve call
quality during VoIP calls. Missing frequency ranges are added to the voice
signal to achieve more natural speech reproduction and make speech
easier to understand. In particular, the quality with which voice signals trans-
mitted over connections with lower band width can be reproduced can be
improved in this way.
Note:
Automatic bandwidth amplification was developed to improve
voice signals. However if calls are made in environments with loud
background noises, automatic bandwidth amplification has a negative
effect on voice quality. The replaying of music, s uch as music on hold,
is negatively affected by automatic bandwidth amplification.
Switching Automatic Bandwidth Amplification On/Off
If automatic bandwidth amplification is switched on, missing frequency
ranges are added to the voice signal, to improve the call quality. If automatic
bandwidth amplification is switched off, the voice signal is reproduced
unchanged.
