Wired VoIP desk phone with a 3.5-in 320 x 240 display, Gigabit Ethernet, PoE power and SIP security features including SRTP and TLS
The Polycom VVX 501 is a wired VoIP desk phone built for office workers who need a dedicated handset with a 3.5-in colour display. It runs on Power over Ethernet and supports SIP signalling for compatibility with standard IP-PBX platforms.
This model suits knowledge workers who want a simple, secure handset with encrypted configuration and 802.1X network authentication. Buyers who need a colour touchscreen, video calling, wireless connectivity or a larger display should look at other models.
The single specification that decides fit is the 10/100/1000Base-TX Ethernet interface powered entirely by PoE. If your network drops cannot supply PoE or you require a separate power adapter, this handset will not operate.

Plug the Ethernet cable into the 10/100/1000Base-TX port on a PoE-enabled switch; the step often missed is confirming the switch port delivers IEEE 802.3 power so the phone starts without a separate adapter.
The 3.5-in TFT LCD display at QVGA 320 x 240 pixel resolution is the component most likely to require replacement if backlight degradation or pixel faults appear over time.
The 10/100/1000Base-TX network interface caps throughput at 1000 Mbps, so sustained heavy SIP signalling and SRTP media streams will hit that bandwidth ceiling before any other resource.
