The SoundPoint IP 335 is a two-line SIP phone that covers the standard office desk without anything you don't need — HD Voice audio, a backlit display, and a full-duplex speakerphone in a compact footprint.
Compatibility
Works with virtually any standard SIP platform (requires SIP 3.2.2 or later), including hosted VoIP services and on-prem PBX systems such as 3CX, FreePBX, Asterisk, and most SIP trunking providers. Supports central provisioning via FTP/TFTP/HTTP/HTTPS for multi-phone deployments. Not compatible with proprietary digital phone systems.
Why offices pick the IP 335
It's the phone for desks where calls are simple and reliability matters. Polycom's HD Voice with wideband G.722 makes conversations sound natural, not tinny. The two-port Ethernet switch means the phone and a PC share one network drop. Three-way conferencing is built in, and a dedicated RJ-9 headset jack handles hands-free work. Central provisioning makes deploying ten or fifty of these as easy as deploying one.
Power: PoE by default
This phone is powered by Power over Ethernet (802.3af Class 2) — plug it into a PoE switch and it's on, no power brick needed. If your network doesn't provide PoE, choose the Add Power Supply option above and we'll include the AC adapter.

About our refurbished equipment
This is professionally refurbished business equipment, fully tested and backed by our warranty. Most of it came off the desks of real offices, so expect light signs of use — minor scratches, scuffs, or slight discoloration are normal. What you won't get is a phone that doesn't work: every unit is tested on a live system before it ships, and if anything's wrong, our warranty has you covered. You're buying function, reliability, and a fraction of the price of new — not showroom cosmetics.
