WHM631 with Charging Cable is a DECT headset working with W70B DECT base/W80 Multi-Cell System/W90 Multi-Cell System to provide such flexibility. The headset can register to the DECT base directly as a stand-alone device or share a SIP account with a DECT handset to dial out or manage the call. With DECT technology, the headset can provide a stable connection and excellent operating range of up to 220 meters. So you can move freely on the floor without worrying about headset range. Besides the basic calling features like the answer, reject, hold, and mute, the headset also has a Push-to-Talk feature. You can send instant Push-to-Talk messages or set up a full-duplex Push-to- Talk meeting via the headset to ensure the whole team is tightly connected. The intercom feature also allows you to make internal calls without a network, and the intercom call is free. Also, the headsets can provide you with all-day wear comfort.
