There are two things most phone system guides won’t tell you. First, the right answer genuinely depends on your specific situation — company size, internet reliability, how many people work remotely, whether you own or lease your building. Second, most guides are written by vendors who only sell one type of system, so they tell you that type is always best. Phonewire installs both on-premises and cloud-hosted systems. Here’s the honest framework for figuring out which one is right for you.
Start Here: The Two Decisions That Actually Matter
Every business phone system choice ultimately comes down to two questions. Everything else — features, phones, apps, integrations — follows from these.
Question 1: On-premises hardware at your location, or cloud-hosted? This is the most important structural decision and the one most buyers don’t fully understand before they start shopping. It determines your pricing model, your control over the system, how failover works, and what happens when something needs to be changed or fixed.
Question 2: How many users, and how many are in the office vs. remote? This drives cost comparison between the two models and determines which features matter most in your day-to-day operation.
Answer those two questions and the rest of the decision falls into place quickly.
On-Premises vs. Cloud-Hosted — The Honest Trade-Off
On-premises (the Phonewire Hybrid): Hardware installed at your location. You own the system. A one-time hardware cost ($3,499) plus an annual license ($699/year for up to 20 users). After year one, your total monthly cost is roughly $58/month in licensing — dramatically lower than per-user cloud pricing as your team grows. The system includes a built-in cellular failover module so your phones keep working even when your internet goes down. You control everything: extensions, routing, voicemail, auto-attendant. Nothing changes unless you change it.
Cloud-hosted: The system lives in a data center. You pay per user per month ($25/user/month with Phonewire). No hardware to buy or maintain beyond the desk phones themselves. Updates happen automatically. Easy to add users instantly. Works from anywhere with internet. Better fit for distributed teams and businesses that prefer predictable per-seat pricing over capital expenditure.
Internet Reliability at Your Location
Both on-premises and cloud-hosted VoIP systems require internet to function under normal conditions. The question is what happens when your internet goes down.
With the Phonewire Hybrid on-premises system, the answer is simple: the built-in cellular module detects the outage within seconds and automatically routes calls over the cellular network. Your desk phones keep ringing. Your staff and your callers never know it happened.
With a cloud-hosted system, failover requires either a backup internet circuit or automatic call forwarding to cell phones. Both are configurable, but they require planning during setup — and call forwarding means your staff takes calls on personal devices rather than their desk phones.
If your location has a single ISP and you’ve experienced internet outages, the Hybrid’s built-in cellular failover option is the cleanest solution available. If you have redundant internet or primarily work remotely, cloud-hosted handles outages adequately with proper configuration.
How Many People Work Remotely or Between Locations
Both systems support remote workers — but the mechanism is different and it matters.
With either system, the Linkus UC mobile and desktop app gives remote employees a full business extension on their existing iPhone, Android, Mac, or Windows device. They call and receive calls using the business number, transfer to colleagues, access voicemail — the full PBX experience, from anywhere.
If your entire team is remote, cloud-hosted has a slight edge: there’s no on-premises hardware to maintain at a physical location you may not occupy consistently. If you have a mix of in-office and remote staff — the most common scenario — both systems handle it equally well. The Linkus app works identically on both.
Features That Actually Matter for Small Businesses
Most feature comparison lists are padded. Here are the features that small business owners actually use and that actually affect how the system performs day-to-day:
Auto-attendant: The virtual receptionist that answers calls and routes them to the right person or department. Every modern VoIP system includes this. What varies is how easy it is to configure and change. Phonewire programs yours before installation day — you don’t need to figure it out yourself.
Voicemail to email: Every missed call delivers an audio file to your inbox within seconds. Combined with voicemail transcription, you can read messages without listening. This alone is worth the switch for most small offices.
Business texting: SMS text messaging from your main business number — on a desktop app and mobile. Clients text the same number they call. Staff respond from a shared inbox without using personal cell numbers.
BLF (Busy Lamp Field) keys: Programmable buttons on your desk phone that show real-time status of colleagues’ extensions. Essential for receptionists and anyone who transfers calls frequently. Not available on softphone-only setups.
Call recording: Available on both systems. Most useful for sales teams, customer service, and any business with compliance requirements (legal, financial, healthcare).
Cellular data failover: Only available on the P560 on-premises system — it’s built into the hardware. Cloud-hosted failover requires either a backup ISP or call forwarding to personal devices.
Installation and Ongoing Support
This is the factor most guides skip entirely, and it’s the one that determines whether your phone system actually works the way you expected after the installer leaves.
Self-install cloud VoIP providers (RingCentral, 8×8, Nextiva, Vonage) ship you phones and expect you to configure extensions, program BLF keys, set up call routing, and train your staff yourself. For a one-person office with technical comfort, that’s fine. For a 15-person law firm with a reception desk, it’s a recipe for a system that’s half-configured a month after cutover.
Phonewire sends an installation technician to your location. Every phone is pre-configured before arrival — extensions labeled, BLF keys programmed, auto-attendant recorded, voicemail set up. Staff training happens on installation day. The phones work when we leave. If something needs to change after installation, Phonewire’s U.S.-based support answers in under a minute — no ticket queue, no overseas call center.
If you’ve been burned by a national VoIP provider’s support experience, this is the most meaningful differentiator between Phonewire and the self-service alternatives.
What You’re Replacing — and Whether Your Numbers Port
Your existing business phone numbers port to either system. Number porting typically takes 2–5 business days. During the port window, your old system stays live — Phonewire runs the old system in parallel until cutover day, so there is no gap in service.
If you’re replacing a legacy system (Avaya, Mitel, NEC, Nortel, Toshiba, or others), Phonewire handles those migrations specifically. The old system stays operational until the new one is fully installed and tested. Cutover is a single scheduled event, typically completed in a morning.
If you’re replacing copper POTS lines as part of the transition, those lines are retired as part of the installation and replaced with SIP trunks over your internet connection — typically at significantly lower monthly cost than your current per-line fees.

Choose the Hybrid on-premises system if: You have 28 or more users and plan to stay in the same location for 2+ years. You want the lowest possible 5-year cost. Your internet has had reliability issues. You have a reception desk that needs BLF key panels. You want a system where nothing changes unless you decide to change it.
Choose cloud-hosted if: Most of your team works remotely or travels frequently. You prefer per-user monthly pricing with no capital expenditure. You have fewer than 8 users (the per-user cost math works in cloud’s favor at smaller team sizes). You want to add or remove users instantly without calling anyone.
Choose both on the same system if: You have a mix — some employees at fixed desks who benefit from physical phones, and some remote employees who need the Linkus mobile app. Phonewire’s systems support desk phones and the mobile app simultaneously on the same platform with no per-device licensing complexity.
What Phonewire Actually Installs
Both the on-premises hybrid and cloud-hosted systems run on the same underlying platform. Same extensions, same dial plan, same auto-attendant, same voicemail to email, same Linkus UC app. The difference is where the hardware lives.
Desk phones: Yealink, Snom, Poly, and Panasonic — all open SIP, all professional-grade, all configured before delivery. Softphone: Linkus UC for iOS, Android, Mac, and Windows — included with both systems. Add-ons available: business texting, voicemail transcription, intercom and paging, elevator emergency phone service.
