Voice over LTE (VoLTE) is still in the early stages of rollout in the Americas and Europe. VoLTE mobile calls vary from traditional 2G and 3G mobile calls because the LTE data network will transmit voice in the same way that it transmits data. Voice calls will be delivered through packets similar to emails, messaging apps, and other communications.
The most noticeable benefit of VoLTE is HD Audio which makes voices sound rich and more life-like over the phone. With VoLTE, callers will eventually be able to integrate video chat or calls straight from the phone without a separate app. VoLTE will also drive faster call setup times and will eventually better integrate with voice over Wi-Fi service for improved coverage.
Many variables need to be met in order to experience a true VoLTE call.
Plantronics Voyager Edge and Voyager Legend support HD Audio when wideband is enabled using the MyHeadset Updater tool for PC and Mac.
User can confirm that HD Voice (Wideband Audio) is toggled on using either the My Headset Updater tool or the Plantronics Hub™ app for iOS or Android from Plantronics.com
HD Audio (Wideband) is standard on Explorer 500, Marque 2 M165, M95, M90 and M70 headsets.
