It is a wireless standard that can give you up to 500 feet of range. It is different from Bluetooth® which gives you about 33 feet of range. If you are concerned about the security of your wireless call, DECT is encrypted, so no one will be able to listen in. Use a DECT headset with your desk phone so you can get up and walk around instead of always having to be at your desk.
ZUM DECT 6.0 Headset™ includes a comfortable headset with noise cancellation so you can hear and be heard well. The Base Unit recharges the headset and will work up to 7 hours on one charge. There is a Remote Handset Lifter RHL-2010 available (sold separately) which allows you answer and hang up even if you’re not near the phone, making it even easier to walk away from the desk without missing a call. If you spend a lot of time on the phone, this product will give you flexibility and freedom of movement you never had before.
