A business phone system that works wherever your team does.
Cloud-based business calling with desk phones, mobile and desktop apps, messaging, meetings and centralized administration, configured and supported by Sterling IT.
Your business phone system, delivered over the internet.
VoIP replaces traditional phone lines with a cloud-hosted system. Employees can use desk phones, computers and mobile apps while keeping company numbers, extensions, voicemail and call routing under one system.
We handle the setup and the ongoing support.
Number porting, desk phones, extensions, auto attendants, call routing, user setup and training can all be coordinated through Sterling IT instead of juggling a separate phone vendor.

One number. Multiple devices. Fewer phone-system headaches.
A cloud phone system is especially useful for businesses with remote employees, multiple offices, mobile staff or changing call-routing needs.
Capabilities vary by plan.
Features such as SMS, archiving, advanced analytics, contact center and AI functions depend on the selected service level. We match the plan to the business rather than pretending every user needs every feature.
Business VoIP FAQ
Can we keep our existing phone numbers?
In most cases, existing numbers can be ported to the new service. We verify portability and coordinate the porting process before cutover.
Do employees need desk phones?
No. Depending on the workflow, users can work from supported desk phones, desktop applications, mobile applications or a combination of devices.
What happens if our internet goes down?
Because VoIP depends on connectivity, internet resilience matters. We can design call-routing and network options around the business's tolerance for outages, including mobile apps and internet failover where appropriate.
