If you're running an office or facility with 75 to 100 phones, the per-user math at the big providers has probably stopped making sense. At RingCentral’s $35 or Vonage’s $29.99 a user, a 100-seat system runs about $180,000 over five years — before the add-ons for queues, recording, and AI answering.
This system is the alternative: a complete, enterprise-scale Cisco IP PBX sized for 100 desks, with SIP Express Plus phone service included. It's the same class of hardware Fortune 500 networks run on — priced right for a company your size. You get reception phones, sidecars for busy front desks, wireless handsets for roaming staff, and an auto-attendant that routes every caller to the right department.
And you don't set any of it up yourself. Our Certified Network Specialists configure your system before it ships, finish the setup remotely, and manage it from there. No monthly rent — that's why it costs less.
At up to 79% off, the natural question is: what's the catch? There isn't one. This is the same enterprise Cisco hardware the Fortune 500 runs on — the Cisco ISR 4351 router, Cisco 8841 and 8851 IP phones — refurbished to like-new condition, fully tested, and built to run for a decade.
The price is low because the model is different. There's no big-provider ad budget or stock price built into it. You buy a real system once, at a price that reflects what the hardware actually costs — plus SIP Express Plus for the service, warranty, and support. Enterprise quality at small-business prices. That's the whole idea.
This isn't a DIY project. Our Certified Network Specialists handle the technical end from start to finish.
The "expensive" on-premise system is actually the most affordable option over any reasonable timeframe.
Over five years, versus the big providers’ 100-seat plans. Every system is customized — request a proposal for your exact numbers.
Your 100-phone system includes 100 SIP lines through SIP Express Plus — HD audio phone service, with no separate carrier to manage. One package covers your phone service, lifetime hardware warranty, and technical support, instead of three separate bills.
100 SIP phone lines with HD audio calling, managed by VoIP PBX Express
Billed per user tier (76–100 users). As long as SIP Express Plus is active, your hardware warranty stays in force for life. See the SIP Express Plus Terms for the full pricing breakdown.

"Perfect system for a low budget!"
You own the system — one purchase, plus service. That's where the savings come from. Where hosted genuinely fits better: you want zero hardware on-site and a pure monthly bill — which is exactly what our own Cloud Express offers at $15.75/user with the phone included, so compare all three columns before you decide. For an office this size, owning an enterprise Cisco system — set up and managed for you — will cost far less over five years. Ask for the proposal with the hosted and owned math side by side; we sell both, so you get a straight answer.
This bundle includes SIP Express Plus phone service (from $431 / month for 100 lines) and a lifetime warranty. The standalone system is hardware-only — you bring your own phone lines. This bundle gives you a lower upfront cost ($6,175 vs $19,500) because SIP service is included.
Yes. Over 5 years, this system costs about $32,035 total. A comparable 100-seat cloud plan runs roughly $180,000 at $30/user — a saving of around $147,965. Every system is customized, so request a proposal for your exact numbers.
SIP Express Plus is our managed phone line service. It provides 100 SIP trunks (phone lines) with HD audio calling from $431/month for the whole system — one base rate, not per phone. Our Certified Network Specialists manage the service end-to-end, so you don't need a separate phone carrier.
As long as your SIP Express Plus service is active, your entire phone system — router, phones, and all components — is covered by our lifetime hardware warranty. No extra cost, no separate plan to purchase.
Yes. We can port your existing phone numbers to SIP Express Plus. The process typically takes 5–10 business days, and our Certified Network Specialists handle all the paperwork.
Yes. Cisco CME supports softphones on Android, iPhone, Mac, and PC. Remote workers connect just like they would with a cloud system.
