Telecommunication has undergone many technological phases starting from analog to digital, wired to wireless and gradually evolved to VoIP technology which is rapidly gaining ground against traditional telephone technology. Though continuous advancement in communication technology had significantly improved the way of communication, however, voice quality is still restricted to nominal standards of narrow-band audio codecs. The adoption of VoIP has provided the opportunity to move beyond the set standards of PSTN "toll-quality voice" and get introduced to a new world of high-definition voice. High-Definition Voice offers wide-band audio making communication more clear, effective and lively.

Matrix SETU VP248SE is a High-Definition VoIP Phone built with superior acoustics and elegant design to provide unsurpassed audio quality and rich user experience. The wide-band technology adds a new dimension to voice based communication.
