Yealink T42S

The Yealink T42S is a 12-line SIP phone that works with virtually any VoIP platform — RingCentral, 8x8, Nextiva, 3CX, FreePBX, and any standard SIP service. Gigabit ports, PoE, Opus codec support, and Yealink's clean provisioning make it a favorite for hosted VoIP rollouts. We have 160+ refurbished units in stock, factory reset, tested, and warrantied, with replacement handsets (500+ in stock) when originals wear out. Sister models T41S, T46S, and T48S share the same platform if you're building a tiered deployment — basic desks to touchscreen executive sets, all provisioning identically.
