12-Line Business VoIP Phone

The Polycom VVX 450 is a wired SIP desk phone built for office staff who handle multiple concurrent calls. Its twelve-line capacity suits receptionists, executives and small teams needing clear call management without a separate expansion module. The handset supports SDP signalling and IEEE 802.1X authentication for secure network access.

Dual Gigabit Ports and Colour Display

Two 10/100/1000 Ethernet ports allow the phone and a PC to share a single wall jack while maintaining full gigabit throughput. A 4.3 inch colour LCD at 480x272 pixel resolution shows line status, directories and XML applications at a glance. The unit measures 9.40 by 9.10 by 2.20 inches and weighs 2.23 lbs for stable desktop placement.

Upgrade from Basic SIP Handsets

This model replaces single-line or monochrome phones when a business adds staff, adopts unified communications or needs TLS encryption for compliance. The jump is worth it when call volume exceeds a handful of lines and users benefit from visual call control on a colour screen.

Questions about this item

What does the dual 10/100/1000 Ethernet ports limit in practice?

The two gigabit ports cap wired throughput at 1000 Mbps each, so the phone and a daisy-chained PC share the same 1 Gbps uplink.

What desk space do the 9.40 x 9.10 x 2.20 inch dimensions need?

The footprint is roughly 9.4 by 9.1 inches with a 2.2 inch profile, so allow that much clear desktop area plus cable bend radius at the rear.

How is the VVX 450 powered, and what step do installers often miss?

It uses Power over Ethernet — plug the LAN cable into a PoE switch or injector; the common mistake is connecting to a non-PoE port and wondering why the screen stays dark.
