What's the difference between the VVX 101 and VVX 150?

The 150 adds a second SIP line, an RJ9 headset jack, a slightly more capable speakerphone, and the Opus codec. Same screen, same form factor, same 100Base Ethernet. If anyone is going to wear a headset on the phone, you need the 150 minimum.

Does the VVX 150 support EHS for wireless headsets?

Yes — via the Plantronics/Poly APP-51 EHS adapter, sold separately. The adapter plugs into the headset jack and the back of a Savi or CS-series wireless base, letting the phone answer and end calls remotely from the headset.

Can I run the VVX 150 without PoE?

Yes, but you'll need a 5V/600mA Poly power adapter (sold separately). PoE is the cleaner option — one cable, no wall wart — and most modern Ethernet switches that businesses already have will power it.

Does it support gigabit Ethernet?

No. The VVX 150 has dual 10/100 Mbps ports, which is fine for the phone but caps anyone hooked into the back pass-through port at 100 Mbps. If you need gigabit at the desk, get the VVX 250.

Poly · VVX series · entry 2-line

Poly VVX 150A entry 2-line that just keeps working.

The VVX 150 is the VVX 101's pragmatic sibling: a second SIP line, an RJ9 headset jack, a full-duplex speakerphone tuned a little hotter, and a 2.5-inch greyscale display. It's the cheapest VVX we'd put on an actual desk where someone is going to take real calls — and at under $100 it's the volume entry pick for small offices that want Poly hardware without the color-screen tax.

Poly VVX 150 VoIP desk phone — front view with handset and dialpad — Poly VVX 150

Why the VVX 150 is on the catalog.

The VVX 150 is the phone we recommend to small offices that want a Poly handset, don't need color, and don't want to spend more than $100. It does the two things people actually need: it has a second line for queue overflow or shared mailboxes, and it has an RJ9 headset jack so the person sitting in front of it can take calls hands-free. Beyond that, it's deliberately spec-light — no USB, no Bluetooth, no gigabit, no color — and that's where the price comes from.

What you get for the money is Poly's audio. The handset uses the same HD voice transducer the entire VVX family ships, the speakerphone is full-duplex with proper acoustic echo cancellation, and the codec list runs all the way up to Opus, so the phone holds up over a marginal residential ISP about as well as anything you can buy at any price.

Where it isn't the right phone: if you have a receptionist or office manager who handles five or more lines, the 150 will feel cramped — two line keys plus four soft keys is not enough surface area, and you can't add a sidecar. Step up to the VVX 301 or VVX 350. If your team is on video calls all day and uses USB headsets, the 150's analog-only headset jack is a frustration — the VVX 250 (which adds USB) is only about $40 more and worth it.

How it works on voip.army.

Plug the VVX 150 into PoE and ethernet. About a minute later it has registered to your extension. Same auto-provisioning flow as every other supported phone — no SIP credentials to type, no firmware to chase.

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.

100M

Ethernet to the workstation

10/100 Mbps pass-through is fine for voice but caps a daisy-chained workstation at 100 Mbps.

—

USB headset ports

No USB. Wired RJ9 headset jack only (if equipped).

802.3af

PoE class

Class 2 on most VVX. Any standard 802.3af switch powers it; no separate adapter needed.
