Polycom VVX 311 IP Desk Phone 6 Line Greyscale Display Gigabit Ethernet PoE Ships With North America Power Supply 2200-48350-001

End of life. Polycom has discontinued the VVX 311, and this phone is past END OF SUPPORT as well as end of sale. Poly publishes the schedule: end of sale 31 March 2020, last time ship Q2 2020, end of support Q4 2025. Every one of those dates is now behind us. The named successors were the VVX 250 and the VVX 350, both of which are themselves end of sale, so the live replacement path is the Edge E Series. Barcode Printer Shop does not currently stock a successor mapped to this part number, so none is linked here. What is still true: the last firmware, UC Software 6.4.6 of November 2023, does list the VVX 301 and VVX 311 among supported devices, so a working unit runs supported-era software. There will simply be no further releases and no support entitlement. Remaining stock is sold for fleet matching, replacement units and validated workflows where requalifying a new model is not practical.

Key Features

• This is the only VVX 311 part number that ships with a power supply. Poly's own SKU string reads Ships with Universal Power Supply with NA Power Plug.
• The plug is North American. The adapter is described as universal but this is a US-plug configuration.
• It carries NO Skype for Business licence. That is the other VVX 311 part number, 2200-48350-019, and it is the only other difference between the two.
• The phone runs fully on PoE at 802.3af Class 2, so on a PoE switch the bundled adapter is redundant and the cheaper PoE-only part number is the better buy.
• Six programmable line keys with HD Voice on the speaker, handset and headset paths to 7 kHz.
• Greyscale display, not colour: 3.2 in backlit 8-level greyscale LCD at 208 by 104.
• There is NO USB port on the VVX 311, so no USB headset and no USB Wi-Fi accessory.
• No Bluetooth and no Wi-Fi, and no accessory path to either.
• Dedicated RJ-9 headset port with electronic hook switch support.
• This phone is NOT antimicrobial. The VVX 311 predates Poly's Microban programme and no such claim appears in its datasheet.
• Two Ethernet ports at 10/100/1000, so the desk PC shares the drop.
• Past end of support. Poly's schedule gives end of sale as 31 March 2020 and end of support as Q4 2025.

The power supply

This is the whole reason this part number exists. Poly's own description string for 2200-48350-001 reads, as one unbroken sentence, Polycom VVX 311 6-Line Desktop Phone Gigabit Ethernet with HD Voice, Ships with Universal Power Supply with NA Power Plug. The other VVX 311 part numbers ship without one. The adapter is a 48 V DC unit at 0.3 A and the plug is North American, so despite the word universal in Poly's string this is a US-market configuration. A dealer packing list for this exact number adds a ferrite clamp, but that item is attested by the dealer only and is not claimed here. Note that 2200-48350-001 does not appear in Poly's own ordering table at all: it is a bundle sold alongside the catalogue numbers.

The other difference

There are exactly two differences between this part number and 2200-48350-019, and the power supply is the first. The second is a licence. The -019 build is the Microsoft Skype for Business and Lync edition and includes a paid Polycom UCS SfB/Lync licence; this one does not, and ships the standard Poly UC Software load for Open SIP instead. Everything else is the same phone: the same six lines, the same greyscale panel, the same Gigabit ports, the same 802.3af Class 2 power draw, the same chassis. No source positively labels this SKU Open SIP, so the safe statement is the negative one: it carries no Skype for Business entitlement.

Do you need it

Ask what the switch port does before ordering this part number rather than the cheaper PoE-only one. The VVX 311 is an 802.3af Class 2 device and runs completely from Power over Ethernet, so on any PoE switch or injector the bundled adapter goes in a drawer and stays there. That makes the premium on this SKU worth paying in exactly one situation: the desk drop has no PoE. That covers small offices on unmanaged switches, temporary desks patched into a wall socket, and home workers. Everywhere else, buy the PoE-only number and save the money. Getting this wrong in the other direction is worse: a PoE-only phone on an unpowered port does not start at all.

What it lacks

The VVX 311 has no USB port. Three separate passes across two Poly documents returned nothing for USB, and one of those documents lists USB among its explicitly absent sections. That rules out a USB headset and it rules out any USB Wi-Fi accessory, because there is nothing to plug one into. There is no Bluetooth and no Wi-Fi either. The display is a 3.2 in backlit 8-level greyscale LCD at 208 by 104 pixels, and any listing calling it colour has borrowed the specification from a VVX 350. There is no expansion module support: one datasheet pass found a sentence about readiness for future modules, which is a marketing promise rather than a shipping capability.

Not antimicrobial

A claim to remove rather than repeat. The VVX 311 is not antimicrobial and carries no Microban protection. Asked explicitly whether the words antimicrobial or Microban appear anywhere in the Polycom VVX 300, 301, 310 and 311 datasheet, the answer was that they do not, and a second pass of the same document surfaced no such text either. This phone predates the programme entirely. Microban does appear on Poly's later hardware, including the VVX 350 and the Edge E models, which is almost certainly where the claim on competing VVX 311 listings has come from. For a clinical, food handling or shared-desk requirement where surface treatment is a specification rather than a preference, this is the wrong phone.

Audio and headsets

Where the VVX 311 still holds up is the audio, which was always the reason to buy Polycom. HD Voice runs to 7 kHz on all three paths - speaker, handset and headset - and Polycom Acoustic Clarity provides full-duplex hands-free conversation, so both ends can talk at once without the speakerphone clipping. The codec list is G.711 in both A-law and mu-law, G.729AB, G.722, G.722.1 and iLBC. There is no OPUS on this generation. Headsets attach through the dedicated RJ-9 port, and the phone is electronic hook switch capable, so a wireless headset system with a desk phone base can answer and end calls remotely with the correct EHS cable.

Buying it in 2026

This phone is past end of support, not merely end of sale, and that is stated at the top of this page because it changes the decision. Poly's own schedule gives end of sale as 31 March 2020 and end of support as Q4 2025, and both are behind us. The mitigating fact is real: the last firmware, UC Software 6.4.6 of November 2023, still lists the VVX 301 and VVX 311 as supported devices, so an installed unit is running supported-era software. What has stopped is the pipeline of new releases and the entitlement to support. Buy this to match a fleet, to replace a failed handset, or to hold a validated configuration steady. Do not start a new deployment on it.
