Choosing a used business phone with a headset often comes down to how many handsets you need, how much line capacity matters, and whether wireless connectivity matters. The four VoIP desk phones in this guide cover different starting points, from a two-phone ShoreTel lot to a Poly Edge E450 that names Bluetooth, PoE, Wi-Fi, and Gigabit in its title.
Quick take
If you need two desk phones on the same order, the ShoreTel 230 lot is the lowest listed price here. If you want a Poly with wireless flexibility, the Poly Edge E450 with wireless in the listing is the more connected option. The Yealink SIP-T58A is the factory-reset option. The corded Poly Edge E450 is the companion to the more connected Poly.

Decision matrix
| Use case | Recommended listing | Why |
|---|---|---|
| Two phones for a small workspace | ShoreTel 230 lot (2 phones) | Two handsets, stands, and headsets in one order at the lowest listed price |
| Single Poly with wireless | Poly Edge E450 w/ Bluetooth PoE Wi-Fi | Wireless included in the listing |
| Single factory-reset phone | Yealink SIP-T58A w/ Headset & Stand | Factory reset |
| Poly with corded setup | Poly Edge E450 Corded IP Phone | Corded configuration at a lower listed price than the wireless Poly |
Poly Edge E450 Corded IP Phone - 2201-87030-001
This used Poly Edge E450 is the more direct of the two Poly listings in this comparison. It includes a USB-C interface, an RJ-9 headset jack, and Ethernet connection, and it carries 14 lines. At $109.95, it is $20 lower than the other Poly Edge E450 in this set. The difference is that the higher-priced Poly includes more wireless in its listing, while this one is corded. If you do not need those wireless details, the corded Poly still gives you a familiar Polycom interface at a lower listed price. The limitation is that this configuration does not include the wireless connectivity highlighted in the other listing.
Poly Edge E450 IP Business Phone w/ Bluetooth PoE Wi-Fi Gigabit - 2200-087030-025
This Poly Edge E450 listing at $129.99 is the highest listed price in this comparison. It combines Bluetooth, PoE, Wi-Fi, and Gigabit in one listing. The listing adds a 3.5-inch main color display, a 2.4-inch secondary screen, and support for up to 44 programmable line key functions with 14 line keys. That makes it a strong candidate if you want a used Polycom desk phone with wireless flexibility and power over Ethernet in one unit. The trade-off is the price: it costs $20 more than the corded Poly E450 and $55 more than the Yealink, so you are paying extra for the connectivity features named in the listing.
Lot of 2~ ShoreTel 230 IP 230 VoIP Business Phones - Black Stands- Headsets
This two-phone lot at $10.99 is the lowest listed price in this comparison. The listing includes two ShoreTel 230 IP phones, black stands, and headsets, which makes it the only option here with two complete desk phone setups in one order. Each handset supports 3 lines, so it can handle basic call volume, but it is more limited than the Poly models in this comparison. If your goal is to equip multiple desks without spending much, the ShoreTel lot is the clear choice. The limitation is the modest 3-line capacity per phone, which may feel cramped for users who juggle many calls simultaneously.
Yealink SIP-T58A VOIP Business Phones w/ Headsets& Stand Factory Reset
The Yealink SIP-T58A at $75.00 sits between the ShoreTel lot and the two Poly models on listed price. This listing includes a headset and stand, and the unit is factory reset. Some units have scratches on the screen, and a power adapter is not included, so you may need to supply an adapter before use. If you already have a compatible power source and can accept a little surface wear, the Yealink is a serviceable middle-priced used VoIP phone with a headset included. The limitation is that you are responsible for getting a power adapter and possibly living with visible screen scratches.
Final recommendation
For two phones at once, the ShoreTel 230 lot is the lowest listed price option. For a single Poly with wireless, choose the Edge E450 listing that includes wireless extras. For the Yealink option, the SIP-T58A is the middle-priced choice. For a corded Poly, the other Edge E450 is the more direct choice.
