Description
The Yealink W78P pairs the W70B base station with a W78H cordless handset that supports both Bluetooth and wired headsets. It suits busy offices, retail floors and front desks where staff move around and often take calls on a headset. A vibration alarm and noise cancellation help users catch and hear calls in noisy areas.

Key features
- Bluetooth or wired headset: The W78H handset has built-in Bluetooth 5.1 and a 3.5 mm headset jack, so users can pick the headset that suits them.
- Vibration alert: A vibration alarm helps users notice incoming calls in noisy or stressful situations.
- Large color screen: 2.4" 240 x 320 TFT color screen with an intuitive interface.
- Grows to 10 handsets: Register up to 10 W78H handsets with up to 10 SIP accounts and 20 simultaneous calls, so each handset can handle two calls.
- Quick charging: Up to 21 hours of talk time and up to 320 hours of standby (166 hours on early V0 handsets), in ideal conditions. A 10-minute charge gives 2 hours of talk time.
- Easy to roll out: Supports Yealink RPS (Redirection and Provisioning Service) and auto-provisioning via TFTP/FTP/HTTP/HTTPS with PnP, so IT can set up phones without manual configuration on each one.

Specs are Yealink's, from its current data sheets. Systems show the handset in the box. Range and battery figures are Yealink's "in ideal conditions" numbers, and some handsets list two figures for different hardware versions (V0 to V4). "None listed" means the data sheet names no such feature. Compare all W Series models
