SoundPoint IP 600 vs IP 601 — difference?

Minor firmware refresh and production-process changes — same chassis, same display, same line count, same audio. Interchangeable in a mixed fleet.

Does the SoundPoint IP 601 support HD voice?

No — G.711 and G.729 narrowband only. The IP 650 added G.722 HD voice in the same chassis.

Is the SoundPoint IP 601 still supported on voip.army?

Yes — UCS firmware 4.0.15 on our legacy provisioning VLAN.

What's the modern equivalent?

The Poly VVX 411 — twelve-line color, gigabit, expansion module support, current firmware. About $120 more than a refurbished 601.

Why we still support the SoundPoint IP 601.

The SoundPoint IP 601 was a quiet refresh of the IP 600 in the mid-2000s — same chassis, same six-line layout, same monochrome display, same audio path, with a slightly longer firmware support window. Released around 2005, EOL'd 2012.

Operationally interchangeable with the IP 600 on voip.army's legacy provisioning VLAN. If you have a mixed fleet, the same provisioning template works for both.

For new orders the modern equivalent is the VVX 411 — twelve-line color phone with gigabit, expansion module support, and current UCS firmware. If you specifically want HD voice in the SoundPoint family, the IP 650 is the direct successor with G.722 wideband audio.

How it works on voip.army.

The SoundPoint IP 601 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 6 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.
