RAD Data Communications said Vmux gateways use voice codecs, silence suppression and its TDMoIP multiplexing to minimise the bandwidth needed for voice transmission without affecting features such as voicemail, fax, modem and IVR.
The VMUX features the TDMoIP framing and aggregation technique that delivers superior bandwidth-efficiency, down to 4kb/s per channel and supports voice activity detection (VAD), silence suppression and comfort noise generation (CNG), the company claims.

In addition to the high quality compression and echo cancellation, the Wireless Network Compression solution features silence suppression with superior Voice Activity Detection (VAD) and Comfort Noise Generation (CNG), and intelligent packet loss concealment (PLC) with low-delay and non-blocking.
These technologies include compressed toll quality voice codecs, echo cancellation, silence suppression (voice activity detection and comfort noise generation), adaptive jitter buffer, and packet loss concealment technologies, which are combined to achieve outstanding voice quality and industry leading bandwidth efficiency across any network.
