Retire your aging PBX. We’ll run the new one for you.
Legacy phone systems are getting harder to support, harder to staff for, and harder to justify on the budget. SotirlS hosts 3CX on our infrastructure and operates it for you, so you get modern features, real support, and predictable costs without becoming a phone system administrator.


Expertise you can depend on
60-minute response time
Phone outages don’t wait. Neither do we.
10+ years of 3CX experience
From single-site deployments to multi-facility environments with hundreds of extensions, we’ve run it all.
Direct 3CX vendor escalation
When an issue exceeds our team’s reach, we have direct access to 3CX engineering earned through 3CX’s Advanced Certification, so complex problems don’t sit in a queue.
Everyone’s moving to the cloud. We help you do it right.
Modern business phone systems aren’t just for making calls. They’re a platform for collaboration, customer intelligence, and Al-driven workflows. Call recordings feed coaching tools. Transcription supports compliance and quality assurance. Mobile and web access make extensions truly portable. None of this is possible on analog or aging PBX setups. Organizations holding onto legacy hardware aren’t just maintaining old gear. They’re falling behind where business communication is going.

When clients call us
Most phone-system conversations start with a specific trigger: a deadline, a vendor announcement, or a number that finally got too big to ignore. These are the patterns we see most often.
“Our PBX is going end-of-life”
Major on-prem PBX platforms are sunsetting hardware, dropping support, or forcing migrations to their cloud offerings. We help you plan the exit, design the right setup, and execute the cutover.
“Our IT team is stretched too thin to manage phones”
A small in-house IT team has bigger priorities than VoIP. Day-to-day phone admin eats hours that should go to higher-value work. We take it off their plate entirely.
“We’re moving facilities or opening a new location”
Moving a phone system is one of the hardest parts of a building move. We plan the cutover, port numbers where needed, provision the new site’s hardware, and stay engaged through go-live.
“We have call quality issues no one can fix”
Dropped calls, audio problems, choppy quality. Your current vendor either can’t diagnose it or won’t take ownership. We host directly on supported infrastructure with the experience to root-cause.
A phone system that runs itself, because we’re running it.
With SötirIS-hosted 3CX, you get the features and economics of a modern phone system without taking on the operational work. We run it on our infrastructure, on supported components, with a team that’s done it at scale.
Fully hosted, fully managed
The 3CX server, the SIP trunking, the hardware compatibility, the patching and updates. We own all of it. Your team doesn’t manage a phone system; they make phone calls.
Supported infrastructure, no surprises
Every part of the stack is chosen because it works reliably with 3CX and we can support it end-to-end. SIP trunking through providers we trust, handsets from vendors we provision daily, and no shortcuts that create support gaps.
Run at real scale
We host 3CX environments with hundreds of extensions across multi-facility deployments. This isn’t a side service for our team. It’s a core offering we’ve operated for over a decade.
How a 3CX engagement actually goes
Phone-system projects fail most often at cutover. Here’s how we structure an engagement so they don’t:
Discovery
We evaluate your current environment in detail: call flows, hardware, trunking, voicemail. Onsite where it helps.
Design & Procurement
We design the new environment around your business, spec the right handsets, and coordinate supported SIP trunking.
Build & Test
We build and load the 3CX environment on our infrastructure, configure call flows, and run end-to-end testing.
Cutover Day
We come onsite on the day of porting and stay through the day to confirm the system is operating as designed.
Ongoing Operations
Your phone system becomes our responsibility. We administer, support, and operate it on an ongoing basis.
Everything you need for a modern phone system, in one service.
No piecemeal contracts, no surprise add-on fees. Sotiris-hosted 3CX bundles every component you need: licensing, infrastructure, hardware, support, and ongoing operations.
Hosted 3CX environment
our PBX runs on our infrastructure. We handle patching, monitoring, and updates.
Mobile & web apps
Take your extension anywhere. Calls, voicemail, and chat from desktop, mobile, or browser.
Yealink handsets
Provisioned, configured, and lifecycle-tracked so you know when to plan replacements.
Supported SIP trunking
Voxtelesys or SIPtrunk.com—providers we trust to integrate cleanly with 3CX.
Built-in AI features
3CX’s AI Receptionist and transcription tools, available as part of the platform.
Auto attendants & call flows
We design and configure your routing, menus, and after-hours behavior.
User guides & training
Written guides so your team can use everyday features without calling IT.
Solution Center support
A real engineer when something’s wrong, with 3CX vendor escalation when needed.
Trusted across industries to keep operations running.
Whether it’s a healthcare environment that can’t tolerate downtime or a fast-moving small business, our clients rely on the Sotiris-hosted 3CX phone system every day.
Making the switch from analog phones to VoIP with 3CX transformed the way our team communicates. SotirlS’s support team has been outstanding—any phone issues are acknowledged and addressed quickly, keeping our operations running without interruption. Having a dedicated team that’s reliably responsive has given us real confidence in our phone system.
