Three models cover almost every desk. The short answer: get the Edge E250 unless you need Wi-Fi, in which case get the E350. If budget is the only concern, the older VVX 250 still works.
Here is what distinguishes them and which one to pick for your situation.
The three models
| Model | Connection | Best for |
|---|---|---|
| Poly Edge E250 | Ethernet + Bluetooth | The default. Most desks. |
| Poly Edge E350 | Wi-Fi (5GHz) + Bluetooth | No ethernet at the desk. |
| Poly VVX 250 | Ethernet only | Budget-conscious, ethernet available. |
Edge E250
This is the one we recommend for most people. Color screen, HD voice, Bluetooth for wireless headsets, two ethernet ports so you can daisy-chain a computer through it. Nothing fancy, everything that matters.
If you are not sure, order the E250.
Edge E350
Same phone, plus built-in Wi-Fi. Pick this when you cannot run an ethernet cable to the desk (older office, home worker without a drop, shared space).
Two things to know about Wi-Fi phones:
- 5 GHz only. The E350 does not support 2.4 GHz networks. Your router must have a 5 GHz network published.
- No spaces in the SSID. "My Office Wifi" breaks provisioning. "MyOfficeWifi" is fine.
VVX 250
The previous-generation Poly. Still sold, still supported, still reliable. If you have a drawer of VVX 250s from a prior install, keep using them. If you are buying new and budget is tight, it is a real option.
The main tradeoff versus the E-series is a slightly older interface and no Bluetooth. For a front-desk phone that is mostly used to answer and transfer, you will not notice a difference.
Why only Poly
We support Poly exclusively. Yealink, Grandstream, Cisco, Fanvil, we do not provision any of them.
The reason is operational. Every brand has its own firmware cycle, its own provisioning quirks, its own discontinuation surprises. Supporting all of them means none of them get the attention they deserve. We picked the one we trust and built everything around it.
Your phone then always behaves predictably. Our support always knows the device. Firmware updates always go through our process. That is the tradeoff.
Three phones, three firmware trains, one support team. Everything else is a distraction.
Where to buy
You can buy through us or through any Poly reseller. If you buy through us, the phones arrive pre-provisioned for your account: plug in and go. If you buy elsewhere, send us the MAC address off the back of each phone and we provision against it.
Either way works. Buying through us is usually simpler because we handle the provisioning and the shipping in one step.
