IP320HDE Product Overview

Cutting Edge Voice Quality

Based on AudioCodes’ advanced, robust and field-proven VoIPerfectHD software, AudioCodes’ IP Phones are designed to utilize the most popular wideband coders such as G.722, G.722.2 (WB-AMR), G.729.1, EVRC-B and G.711.1. Each of these phones feature enhanced proprietary capabilities, such as packet loss concealment, high quality wideband acoustic echo canceller, and low-delay adaptive jitter buffers to enrich the HD VoIP experience.

Interoperability

The AudioCodes 300HD Series of High Definition IP Phones is widely interoperable with IP-PBXs, Softswitches and IP Centrex solutions. As Enterprises and Service Providers continue to seek open network architectures that enable them to maximize value and reduce costs, AudioCodes best-of-breed technology, wide interoperability, and adherence to standards make the 300HD Series of High Definition IP Phones a natural selection.

HD VoIP

HD VoIP refers to the use of wideband technology, providing deeper clarity and a better audio experience in VoIP Communications. The traditional Public Switch Telephony Network (PSTN) is limited to 300-3400 Hz for narrowband speech. Voice signals are sampled at a rate of 8 kHz, causing limitations in communication quality and comprehension. In HD VoIP, wideband telephony refers to transmitting speech signals with bandwidths ranging between 50-7000 Hz and a sampling rate of 16 kHz. This effectively doubles the narrowband speech signal bandwidth and offers the caller “true voice” conversation. Compared to narrowband telephony, wideband technology establishes a sense of presence, resulting in a natural and comfortable conversation.
