Is the SoundPoint IP 430 still supported?

Yes — on voip.army's legacy provisioning VLAN running UCS firmware 4.0.15. The phone predates TLS 1.2, so provisioning traffic stays on an isolated network, but call functionality is normal.

Does the SoundPoint IP 430 support HD voice?

Yes — G.722 wideband audio on handset, speaker, and headset. Released alongside the IP 330 in the 2007–2008 Polycom HD voice refresh.

Can I still buy SoundPoint IP 430 new?

No — Polycom EOL'd it in 2015. Our stock is refurbished/pre-owned units from fleet decommissions, tested and re-flashed.

What's the closest modern equivalent?

The Poly VVX 150 — entry-tier two-line desk phone with HD voice, RJ9 headset jack, current UCS firmware. Similar compact footprint.

Polycom SoundPoint IP 430Still works. Still supported.

The SoundPoint IP 430 is the small-footprint two-line HD-voice phone Polycom shipped in the late 2000s — slightly larger display than the 320 series, full SoundPoint handset, designed for compact desks. EOL'd 2015; still supported on voip.army's legacy provisioning network.

Why we still support the SoundPoint IP 430.

The SoundPoint IP 430 was Polycom's compact two-line HD-voice phone — released 2007, EOL'd 2015. The chassis was smaller than the IP 330, the display slightly larger (132×46 instead of 102×33), and the styling more streamlined for executive-style desks where a full-sized SoundPoint felt too bulky.

It became popular in law firms and consulting practices that wanted Polycom's audio on partner desks without the visual footprint of a 330 or 501. We still see them in production at customers who deployed them in 2010 and haven't had a fleet refresh since.

For existing fleets, the 430 onboards onto voip.army's legacy provisioning VLAN running UCS firmware 4.0.15. For new orders the modern compact equivalent is the VVX 150 or VVX 250 — both fit a similar footprint and run the current firmware track.

How it works on voip.army.

The SoundPoint IP 430 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.
