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 transmitted 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.
