An on-premise phone system lives in your building β usually a controller in the phone closet, talking to IP or digital phones on desks. Higher upfront cost, lower per-user fees over time, less dependence on internet quality. We sell, install, and support Mitel, NEC, and Grandstream.
The industry trend is cloud, but on-premise is far from dead. We still install plenty of new on-prem systems and maintain hundreds more. It's the right call when:
Our largest on-premise install base. We sell MiVoice Office (small to mid-size, up to ~250 users) and MiVoice Business (mid-market to enterprise, with multi-site and contact-center capabilities). Mitel phones are well-built, the admin tools are solid, and the platform has matured over decades. More on Mitel β
We sell the UNIVERGE SV9100 (mid-size businesses) and SL2100 (small businesses, 10β50 users). NEC is a strong choice for cost-conscious small businesses that want a real, feature-complete phone system without a cloud subscription. Quality phones, sensible licensing. More on NEC β
We sell the UCM6300 series for businesses that want an on-premise IP-PBX at a lower price point than Mitel or NEC. Good fit for small to mid-size offices that want SIP-native, open-standard equipment.
On-premise pricing varies more than cloud because there's hardware involved. A 25-user system typically lands somewhere between $15,000 and $30,000 for the controller, phones, licensing, installation, and programming. A 100-user system is generally $45,000 to $90,000. SIP trunks for outside calling run separately, typically $15β$25 per channel per month.
Once installed, ongoing costs are: SIP trunks (or PRI/POTS if you keep legacy), any software assurance contracts with the manufacturer, and our Managed Voice service if you want us to keep running the system day-to-day.
The honest tradeoff: On-premise costs more upfront. It usually costs less over 5+ years. Cloud is easier to add users to. On-premise is more resilient to internet problems. Neither is "better" β it depends on what your business actually needs.
Owning an on-premise phone system means you're responsible for it. Software updates, programming changes, troubleshooting when something breaks, escalating to the manufacturer when needed. Most businesses don't want a phone admin on payroll.
That's what Managed Voice is. We take over the day-to-day: adds, moves, changes, software updates, troubleshooting, vendor escalation. Flat monthly fee, no surprise hourly bills. You call us, we make it work.
If your current system is Mitel, NEC, Grandstream, or Avaya β we can likely take over support. Free assessment of your current setup.
