One base station can't cover a 40-desk floor. Calls drop the moment someone walks past the server room. Your team grabs their mobile because the office phone just doesn't reach.
The Yealink W90B-DM fixes that. It's a DECT IP multicell system built around a DECT Manager (W90DM) and base station (W90B) that scales to 60 base stations, 250 handsets, and 250 simultaneous calls — one live call per handset, no dropped handovers.
Handsets roam between zones without a single dropped word. Compatible with Yealink W53H, W56H, W59R, W73H, CP930W, and DD Phone (T54W DD Phone excluded on VIM). DECT encryption with SRTP/TLS keeps voice secure. LDAP, Cloud Contact, XML, and XSI provisioning are built in, so your IT team isn't hand-configuring 80 headsets at 6am on a Monday.
Need more than 60 zones? The optional Virtual Integrator Manager (VIM) layer scales the same architecture to 10 DMs, 600 base stations, and 2,500 simultaneous calls. Same handsets, same managers — just more coverage.
