Business Phone Systems
All-inclusive 3CX phone systems from a 3CX Silver Partner. Hosting, phone lines, desk phones, the mobile app, installation and ongoing support, all for one flat monthly rate and all handled by One-Stop.

Everything Included, One Provider
Most business phone systems come in pieces: software from one company, phone lines from another, desk phones from a third and someone else to install it. When something goes wrong, you’re left figuring out who to call. With One-Stop, it’s one complete package from one provider, at one predictable monthly rate.
- Hosting: your 3CX system runs on One-Stop’s infrastructure and is managed by our team, with nothing to install or maintain at your office.
- Phone lines: the SIP trunks that connect your system to the outside world are included. We port your existing numbers, so customers keep calling the numbers they already know.
- Hardware: desk phones and the equipment your office needs come set up and ready to use.
- Installation: our technicians install and test everything on-site and make sure your network is ready for clear, reliable calls.
- Support: call our team for help, changes or questions. If an issue ever needs 3CX’s own engineers, we handle the escalation for you.
Your Business Number, Wherever You Work
With 3CX, your team can answer calls on a desk phone, from a desktop or web app, or on their cell phone with the 3CX mobile app. Every call shows your business number, so customers never see a personal cell number, and your staff stay reachable whether they’re in the office, at home or on the road.
Because your system is hosted by One-Stop rather than in your building, it keeps working even if your office loses power or internet. Calls can ring through to the mobile app or another location, so your business never goes silent.
Built Around How Your Business Takes Calls
3CX is a complete business phone system, and we configure it to match the way your business works:
- Auto attendants and call menus greet callers and route them by department, time of day or holiday schedule.
- Ring groups, call queues and callbacks make sure calls reach a person instead of voicemail.
- Voicemail to email and call recording for follow-up, training and record keeping.
- Microsoft 365, Teams and CRM integrations bring up a customer’s record the moment they call.
- Wallboards, reports and supervisor tools (listen, whisper and barge-in) help front desks and call centers manage call volume and train staff.
- Video meetings, team chat, live chat, SMS and WhatsApp are also available in the same app for businesses that want to bring more conversations into one place.
A 3CX Silver Partner
One-Stop is a 3CX Silver Partner, a level reserved for resellers whose engineers have completed 3CX’s Advanced Certification. It gives us a dedicated 3CX account manager and direct escalation to 3CX support when needed. For your business, it means the people designing and managing your phone system are trained experts, and you have one company to call for all of it.
The Right Edition for Your Business
3CX comes in several editions, and we’ll recommend the one that fits how your business handles calls:
- SMB: for small offices with a handful of users.
- Professional: the right fit for most businesses, adding paging and intercom, Microsoft 365 and CRM integration and support for multiple locations.
- Enterprise: for larger or mission-critical operations, adding skill-based routing, Microsoft Teams integration and advanced call recording controls.
Features by edition are set by 3CX and may change. We’ll confirm exactly what’s included in your quote.
How It Works
- Plan. We map out your call flow with you: who answers, what callers hear and what happens after hours.
- Build. We set up your system on One-Stop hosting, port your numbers and configure your phone lines.
- Install. Our technicians install and test your desk phones and equipment on-site.
- Train. Short sessions for your staff and front desk, plus quick-start guides for the apps.
- Manage and support. We handle 3CX updates, license renewals, backups and monitoring, and make changes for you, whether it’s adding a new employee, recording a holiday greeting or adding a menu option.
Better Together with One-Stop Internet and Networking
Call quality depends on the network underneath it. Because One-Stop also provides business internet, networking and Wi-Fi across Central PA, we can make sure your connection and network are ready for voice, and you have one number to call if anything isn’t right.
