SummaryHD Voice Overview


High-Definition Voice (HD Voice) allows you to establish calls between supported RingCentral Desk Phones, RingCentral Phone and RingCentral for Mobile with high-quality voice audio. To consistently deliver the highest HD quality possible, RingCentral utilizes the well-regarded OPUS Interactive codec for audio and video, as well as the G.722 codec for audio. 


Key Features & Benefits

• Clear conversation with background noise reduction

• Better call experience within RingCentral services across all endpoints (Desk phones, conference phones, RingCentral Phone and RingCentral Phone for Mobile)

• HD Voice with OPUS Codec is enabled by default on RingCentral Phone and RingCentral Phone for Mobile. It provides a better user experience with more clarity in HD Voice, especially in limited bandwidth and network environment. 



HD Voice is automatically enabled and is available to the following RingCentral plans:

United States and Canada: RingCentral Office Professional, Essentials, Standard, Premium and Ultimate plans.

United Kingdom: RingCentral Office Standard, Premium and Ultimate plans.
