The world's #1 enterprise phone platform, delivered as a service.
Sprinter pairs the 3CX platform — used by 350,000+ businesses including Mercedes, BMW, the NHS, and Holiday Inn — with our own dialtone, white-glove engineering, and Midwest-based support. One vendor, one bill, one point of accountability.

How it works
The 3CX platform + everything 3CX doesn't do
3CX is brilliant software priced like a license, not a subscription. But software alone doesn't give you a working phone system — you still need carriage, install, and someone to call at 3 a.m. That's what Sprinter delivers.
The platform
Open-standard SIP PBX, hosted or on-prem, no per-user fees, full unified communications.
- HD voice, video conferencing, SMS, live chat, WhatsApp
- Auto-attendant, IVR, queues, call recording, reporting
- Microsoft 365 sync, SSO, Teams Direct Routing
- AI transcription, smart voicemail, conversation insights
- Mobile and desktop apps for iOS, Android, Mac, Windows, web
- Bring your own SIP trunk if you want to — open standard
What Sprinter delivers on top
Everything that turns a powerful platform into a phone system that just works.
- We are the dialtone — SIP trunks, local DIDs, toll-free, e911 included
- Site survey, dial-plan design, IVR scripting, QoS engineering
- Hardware staging, provisioning, and on-site cutover
- Number porting from RingCentral, 8x8, Spectrum, AT&T, anywhere
- 24×7 monitoring, hosting in geo-redundant US data centers
- Midwest-based engineers — moves, adds, changes, support

The Sprinter difference
Why most clients pick managed over DIY
3CX is built so IT can self-deploy. Most of our clients would rather have us do it, run it, and answer the calls.
We are your dialtone
3CX is the platform. Sprinter is the carrier. Local numbers, toll-free, e911, porting, and SIP trunks all come from us — one bill, one point of accountability.
Complete engineering, white-glove install
Site survey, dial-plan design, IVR scripting, hardware staging, network QoS, number porting, and on-site cutover. You don't touch a config file.
Midwest-based managed support
3CX is DIY-friendly — but you didn't buy a phone system to manage it. Sprinter engineers handle moves, adds, changes, after-hours tickets, and upgrades.
Fully hosted, fully redundant
We host your 3CX instance in geo-redundant US data centers with automated nightly backups, real-time monitoring, and 99.99% uptime SLA.
Security hardened by default
3CX is Mandiant pen-tested. We layer geo-fencing, fail2ban, SBC protection, and 24×7 fraud monitoring on top — so toll fraud doesn't show up on next month's invoice.
Real training for your team
Live admin training, end-user video library, printed quick-reference cards, and a recorded session for new hires. Not a 90-page PDF and good luck.
Apples to apples
Managed 3CX vs. RingCentral, 8x8, Avaya
Same features. Different math. The per-user subscription model adds up fast as you grow.
Final pricing depends on user count, concurrent call volume, and feature mix. Brand names are property of their respective owners.
Security
Pen-tested by Mandiant. Hardened by Sprinter.
Every 3CX major release is externally pen-tested by Mandiant and scanned by ReversingLabs. 3CX's own infrastructure is protected by CrowdStrike. On top of that, Sprinter hardens every deployment with geo-fencing, SBC protection, real-time fraud monitoring, and TLS/SRTP encryption end-to-end.
- TLS-encrypted signaling, SRTP-encrypted media
- Country-level geo-blocking on SIP and admin
- 24×7 toll-fraud monitoring with auto-shutoff
- MFA on the admin console and end-user web client
- Nightly off-site backups of config and recordings
successful toll fraud incidents on managed clients
platform uptime SLA across geo-redundant US POPs
encryption on every call, every leg
external pen-test on every major release
FAQ
Common questions
What is 3CX and why are we recommending it?+
3CX is the #1 enterprise phone platform globally — over 350,000 installs at companies like Mercedes-Benz, BMW, Coca-Cola, the NHS, and Holiday Inn. It runs on open SIP standards (no vendor lock-in), it's priced by concurrent calls instead of per user, and it includes voice, video, SMS, live chat, WhatsApp, and team messaging in one platform.
If 3CX is so easy to manage, why use Sprinter?+
3CX is designed to be IT-friendly — but most businesses don't want their controller, office manager, or one-person IT team writing dial plans, managing SBCs, porting numbers, or troubleshooting QoS on a Friday afternoon. We deliver 3CX as a fully managed service: we engineer it, we host it, we carry the dialtone, and we answer the phone when something needs to change.
Can we keep our existing phone numbers?+
Yes. We handle the porting paperwork with your current carrier (RingCentral, Spectrum, Frontier, AT&T, Vonage, 8x8 — we've ported from all of them) and coordinate the cutover so there is zero downtime. You own your numbers and can port them away from us in the future if you ever choose to.
Will it work with Microsoft Teams?+
Yes — 3CX integrates natively with Microsoft 365 for user sync and SSO, and the AI Edition supports Teams Direct Routing so your Teams client becomes a full PBX softphone with PSTN dialing. You don't need a separate Microsoft calling plan.
What hardware do we need?+
Most clients use a mix of Yealink/Fanvil/Snom desk phones for reception and conference rooms, plus the 3CX mobile and desktop apps for everyone else. We stage and provision every handset before it ships to your office — plug it in, it works.
What does it actually cost?+
Pricing depends on user count, concurrent call volume, handset mix, and whether you need contact-center features. Because we bundle license, hosting, dialtone, and support into one invoice, your per-user math usually lands at or below what you're paying today — with more included. Send us your current invoice and we'll do a real apples-to-apples comparison.
What about call centers and contact center features?+
3CX includes the contact center features (queues, wallboards, skills-based routing, supervisor barge/whisper, real-time analytics) that competitors charge a premium per-agent upcharge for. We've deployed 100+ seat contact centers on 3CX across the Midwest & nationwide with full Salesforce, HubSpot, and Microsoft Dynamics integration.
