Cordless headset features DECT 6.0 technology to provide high-quality voice and sound; high protection against wiretapping; and a better range than 2.4GHz and 5.8GHz phone systems. Voice command allows you to pick up calls without even pressing a button. Simply say "answer" while the phone is ringing, and the headset will automatically connect to the call. Plus, you can voice dial a name saved in the softphone call manager. Softphone call manager merges Microsoft Lync, Skype, VoIP and landline telephone services for flexible, full-access communication on one convenient system. Caller ID Announce audibly announces the name of the caller so you don't have to scramble for the handset to see who's calling. Unique antenna design and advances in noise-filtering technology provide up to a 500' range. Headset also includes a magnetic charging cradle, conference capability, ringer volume control, one-button answer and more.
