Polycom SoundPoint IP 301Still works. Still supported.

Why we still support the SoundPoint IP 301.

The SoundPoint IP 301 was Polycom's entry-tier business phone in the early 2000s — released in 2003, EOL'd in 2014. Two SIP lines, a tiny monochrome display, the legendary Polycom HD voice handset of that era. We still see hundreds of them in production at customers who deployed them in 2008 and never had a reason to swap them out.

On voip.army the 301 runs SIP firmware 4.0.15 — the last UCS release that supports the 301's hardware. Provisioning still works through our standard auto-config flow. The audio quality holds up surprisingly well for a phone designed twenty years ago; Polycom's acoustic engineering on the handset hasn't been meaningfully improved since.

If you've got a closet full of 301s from a previous PBX cutover, there's no reason to throw them out. We onboard them onto voip.army the same way as any current phone: send us the MAC addresses, factory-reset, plug in. If one fails, replace it with another 301 from the fleet (or with a current VVX 150, which is roughly the spiritual successor).

Where it isn't the right phone: for new desks. The 301 doesn't support TLS 1.2 or modern SRTP modes, so it provisions over HTTP (not HTTPS) on our isolated provisioning VLAN. Two lines is also light for any role beyond a simple individual contributor. New buyers should look at the VVX 150 or VVX 250.
