VOICE OVER LTE HEADSETS

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.

• Both callers need to be on a compatible VoLTE network in a VoLTE coverage area.
• Both phones need to be VoLTE compatible phones
• At least one major carrier also requires you to opt in to LTE for voice online under your account settings.

Poly 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 Poly Hub™ app for iOS or Android from Poly.com

HD Audio (Wideband) is standard on Explorer 500, Marque 2 M165, M95, M90 and M70 headsets.

The wireless operators rollout is still early and work in progress, so solutions are in the works to address common challenges:

• Dropped calls if one person on the VoLTE call leaves LTE coverage or if the signal is too weak
• Only certain devices include 4G LTE radios and are equipped with software that allows VoLTE. (Check with directly with your carrier to see if your mobile phone is VoLTE compatible.)
• Interoperability between carriers is limited. Some of the major carriers are collaborating to address this issue. Contact your wireless provider for up to date news.
