119 desk phones, DECT handsets, and conference units across Yealink, Poly/Polycom, and Grandstream. If your phone is on this list, plug it in and it registers on its own — no SIP credentials to type in, no firmware to chase.
A supported phone isn't just a phone that can register to our SIP server — every standards-compliant phone can do that. A supported phone is one we've tested every firmware revision against, written a provisioning template for, and committed to fixing if a future firmware breaks something. When you plug one in:
There are dozens of SIP-phone manufacturers. We support the three that actually ship working firmware, document their provisioning XML, and respond to enterprise support tickets:
Cisco SPA, Aastra/Mitel, Snom, Fanvil, AudioCodes? They'll register manually as generic SIP, but we don't auto-provision them. If you have a fleet, see our contact page — we'll quote a swap.
The default choice for new deployments. Predictable hardware, clean provisioning, every model from $79 entry-level to $700 video flagship.
Yealink ships more SIP desk phones than any other manufacturer worldwide. We carry the full T-series (entry-level T1X through executive T5X), the CP-series conference phones, and the W-series DECT cordless platform. New customers buying hardware get T31P at the front desk and T46U on the manager's desk — that combination covers 80% of our orders.
Single-line phones for places that need a phone, not a phone system: lobbies, elevators, conference room hand-offs, kitchen counters.
2-6 SIP line keys, monochrome displays, the workhorses for general staff. The T23G is the volume seller — gigabit ethernet, three lines, dirt cheap in bulk.
Replaced the T1/T2 lines starting in 2020. Faster processors, better screens, longer firmware support runway. The T33G is our default front-desk recommendation today.
The phone for people who live on their phone all day. Color screens, USB ports for headsets, expansion module support for receptionists. The T46U is the single most popular VoIP desk phone we ship.
Built-in Wi-Fi and Bluetooth, modern industrial design, optional 720p HD video camera. The phone you put on the C-suite desk.
360° microphone pickup for boardrooms. The CP920 covers up to 6 people; the CP965 fills a 12-seat boardroom; expansion mics extend either one for larger rooms.
For staff who move: medical practices, warehouses, hotels, large shops. Base unit covers up to 100m line-of-sight; up to 10 handsets per base; up to 20 simultaneous calls on multi-cell systems.
The audio specialist. Best speakerphones in the industry, full support for the SoundPoint IP fleet still in service from 2008-onwards.
Polycom (now Poly, owned by HP) built the IP phone industry. Their HD Voice algorithm and Acoustic Fence noise rejection are still the benchmark. We support every VVX-series phone, every shipping Trio conference unit, and the entire SoundPoint IP legacy line — because if you've been on a hosted PBX since 2010, odds are you have a closet full of SoundPoint 335s that still work perfectly.
The phones Polycom built to replace the SoundPoint IP line starting in 2012. VVX 250 is the volume seller; VVX 450 is the workhorse; VVX 601 is the executive flagship before the brand rebranded to "Poly Edge."
The line that built the hosted-PBX industry from 2005-2014. Polycom officially ended new development in 2018, but firmware 4.0.15 from that year still works, and hundreds of thousands of these phones are still on desks. We carry provisioning templates for every SIP-version model so you don't have to replace them.
Replaced the SoundStation IP line in 2015. NoiseBlockAI mutes ambient noise (typing, paper rustling). Trio 8800 is one of the few SIP conference phones that does USB content sharing through HDMI out.
The value play. Strong hardware at half the price of Yealink/Poly equivalents, with provisioning quirks we've mapped out.
Grandstream is the right call when budget is the constraint. The GRP2614 has a 2.8" color screen, 4 lines, gigabit, and Wi-Fi for the price of a Yealink T31P. The trade-off: their firmware ships a little less polished than Yealink's, and their support response time is slower. We pre-test every firmware release before approving it for our fleet, so you never see a regression in the field.
Released 2020, designed specifically for service providers — provisioning, multi-platform redundancy, ZTP, faster firmware update cycle. Replaced the older GXP-series for new deployments. The GRP2614 is the price-performance leader.
The GXP line shipped from 2009-2020 and is still in widespread use. We continue full provisioning support for every model — GXP2170 is still our pick for a 6-line executive phone with sidecar BLF capability under $200.
For mobile staff on a budget. Less elegant than the Yealink W-series but a fraction of the price; the DP750 base supports 10 handsets per base unit.
If your existing phones are on this catalog — even 12-year-old SoundPoint IPs — we onboard them like any new device. Send us the MAC addresses, we add them to our provisioning server, you factory-reset them, plug them in, and they pick up their voip.army config in about 60 seconds. Zero per-device "porting" fees, zero re-imaging.
Phones not on the list? Standards-compliant SIP phones still register manually if you want to configure them yourself. But for any fleet of 5+ unsupported phones, we usually recommend a swap — used Yealink T46 or VVX 411 phones are cheap, and the support hours you save in the first month pay for the replacement.
If your question isn't here, the contact form is monitored by a real engineer, not a chatbot.
Ask the engineering teamIf you've got a fleet of phones not on this list, send us the model. We add new manufacturers when there's real customer demand — and we'll usually have a tested template within 2-3 weeks.
