Built for 75–100 Desks — Without the Cloud Bill

If you're running an office or facility with 75 to 100 phones, the cloud math has probably stopped making sense. At $30 a user, a 100-seat cloud system runs about $180,000 over five years — and you never own a thing. Miss a payment and the phones go dark.

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. A Certified Network Specialist configures your system before it ships, finishes the setup remotely, and manages it from there. No monthly rent — that's why it costs less.

Your Complete 100-Phone Enterprise SIP System

Everything you need to run an enterprise-scale phone system with phone service included. Pre-configured and ready to deploy.

Enterprise Cisco Hardware — Not a Bargain-Bin Box

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 monthly per-user rent funding a national ad budget and a stock price. 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.

You Get the Phones. We Handle Everything Behind Them.

This isn't a DIY project. A Certified Network Specialist handles the technical end from start to finish.

🛠️
We set it up. Your system ships 90% pre-configured. A Certified Network Specialist finishes the setup remotely — most offices are live in under 2 hours.
🔄
We run it. Moves, adds, changes, new extensions, auto-attendant tweaks — you call us, we handle it. No on-site technician visit, no change-order fees.
📡
We manage it. Ongoing monitoring, updates, and support are handled for you, so the phones just work.
📞
One number to call. A Certified Network Specialist who knows your system by name — not an offshore call center, not a ticket queue.
🏆
Cisco-certified hands. 20+ years of voice networking and CCNP-level certification on every build — the same expertise Fortune 500 networks run on.

Where a Cloud Provider Might Fit You Better

No monthly per-user fees to rent your phones — that's where the savings come from.

We only sell what we'd recommend, so here's the honest version. A cloud system like RingCentral or 8x8 can make more sense if:

If that's you, a cloud plan is a reasonable choice. But if you have a real office with 75–100 desks and you plan to be there a while, owning an enterprise Cisco system — set up and managed for you — will cost far less over five years and put you in control of your own phones.
