Polycom VVX 400 Desktop SIP/IP Business Phone with Color Display & HD Voice

Condition: New, open box, display model; power supply is NOT included (requires PoE 48V or a compatible optional PSU purchased separately).

The Polycom VVX 400 is an enterprise desktop SIP/IP VoIP phone designed for high-call-volume office roles where fast call handling and clear audio matter. With a color display, dedicated call-control keys, and HD Voice wideband audio capability, it’s a solid endpoint for hosted PBX or on-prem IP telephony environments. Since this unit does not come with a power adapter, it’s ideal for installations using a PoE-enabled switch (common in business networks), keeping desks cleaner and power centralized.
