SoundPoint IP 330 vs SoundPoint IP 331 — what's different?

Mostly the firmware track. The 331 was a minor refresh that extended firmware support a little further into the 2010s. Hardware is essentially identical.

Is the SoundPoint IP 330 still supported on voip.army?

Yes — on the legacy provisioning VLAN running UCS firmware 4.0.15. The phone can't speak modern TLS for provisioning, so it stays on an isolated network.

Does the SoundPoint IP 330 support HD voice?

Yes — G.722 wideband audio on handset, speaker, and headset. A meaningful step up from the IP 301 / 320, which were narrowband only.

Can I still buy SoundPoint IP 330 new?

No — Polycom EOL'd it in 2014. Our inventory is refurbished/pre-owned units from large fleet decommissions, tested and re-flashed before shipping.

Polycom SoundPoint IP 330Still works. Still supported.

The SoundPoint IP 330 is the HD-voice two-line desk phone Polycom shipped in the late 2000s — same SoundPoint chassis as the 301, but with G.722 wideband audio and standards-compliant PoE. EOL'd in 2014; still supported on voip.army's legacy provisioning network.

Why we still support the SoundPoint IP 330.

The SoundPoint IP 330 was the first HD-voice phone in the entry tier of the SoundPoint family. Same full-sized chassis as the 301, but with the G.722 codec and IEEE 802.3af Class 2 PoE — both meaningful upgrades for late-2000s deployments.

Released 2007, EOL'd 2014. We still onboard hundreds of these each year for customers who deployed them in fleet quantities and want SKU continuity. On voip.army it runs UCS firmware 4.0.15 on our legacy provisioning VLAN.

For new orders the closest current equivalent is the VVX 150 or VVX 250 — both two-line, both HD voice, both running current UCS firmware on our main provisioning track.

How it works on voip.army.

The SoundPoint IP 330 runs Polycom UCS firmware 4.0.15 — the last release that supports this hardware. It onboards onto voip.army the same way as any current phone, just on our legacy provisioning VLAN because the phone's TLS stack predates modern web standards. Call quality is normal SRTP.

60s

Time from plug-in to first call

Boot, fetch config from our provisioning server, register, ready. About one minute on a normal internet connection.

SIP accounts on one phone

Run up to 2 simultaneous SIP registrations. Each line key has a dual-color LED for status.

Per-device onboarding fees

Bringing your own? Send us the MAC, factory-reset, plug in. No charge to add it to the fleet.

4.0.15

UCS firmware version

Last firmware Polycom shipped for this phone (2018). Still works perfectly on voip.army; provisions over our isolated legacy VLAN because the phone can't speak TLS 1.2.

100m

Ethernet to the workstation

PC pass-through port on the back lets you daisy-chain a single ethernet drop to phone and computer.

802.3af

PoE class

Class 2. Any 802.3af-compliant switch from the last 15 years will power it without issue.
