Description
The Yealink W70B is the single-cell IP DECT base station of the W7 range, designed for small and medium-sized businesses. It registers up to 10 SIP accounts and 10 handsets, handles 20 simultaneous calls and 3 parallel conferences, and its coverage grows with up to 5 RT20 or 6 RT30 repeaters. It accepts the W56H, W57R, W59R Pro, W71H, W73H, W74H and W78H handsets, the CP930W conference phone and DD phones. The Opus codec, alongside G.722, AMR-WB, G.726, G.729 and iLBC, keeps the voice clear even on a poor-quality network. The RJ45 10/100 port is powered over PoE 802.3af, and a 5 V power adapter is supplied for installations without PoE. The compact housing hides the cables and sits on a desk or mounts on a wall. Provisioning goes through Yealink's RPS service and auto-provisioning, with TLS, HTTPS and 802.1x security.

Use and tips
The W70B is the base to pick to create a DECT system in a shop, a practice, a restaurant, a workshop or medium-sized offices, or to replace an older base while keeping the compatible handsets. Supplied on its own, it is completed with the handsets of your choice, up to 10, and an RT30 repeater if coverage must go beyond one floor. It registers on the IP PBX like a SIP phone and runs on PoE, with the supplied power adapter serving when no PoE switch is available. Beyond 10 handsets or to cover several buildings, move to the W75 mini multi-cell base or the W80 and W90 systems.
