Still Using Traditional Phone Lines? Here’s What That Means

Many businesses still have systems that rely on traditional copper phone lines — often without realizing it. This can include:

  • Older office phone systems
  • Fax machines
  • Fire alarm panels
  • Elevator emergency phones
  • Security and access control systems

Not all of these can move to standard Voice over Internet Protocol (VoIP). Some require different solutions to remain reliable and compliant.

We identify what you have and make sure each system is transitioned the right way — not just the easy way.

Frequently Asked Questions

What happens to our current phone system and lines?

We start by understanding what you have today — including your phone system, numbers, and any lines or systems connected to it. From there, we design a transition that keeps what works, replaces what doesn’t, and avoids unnecessary disruption.

Will this affect other systems in our business?

Sometimes. Certain systems — like alarms, access control, or other equipment — may be connected to your phone setup. If they are, we make sure they continue working properly as part of the transition.

Do we need to replace everything at once?

No. Most businesses transition in phases — starting with phones and addressing other systems as needed.

Will I lose anything from my current PBX system?

No. Our cloud-based platform provides all of the functionality of a traditional PBX — like call routing, extensions and professional greetings — without the need for a physical equipment on your premises. Our modern cloud PBX is managed entirely by our local team.

Can I keep my existing business phone numbers?

Yes. As part of our managed service, we handle the entire process of porting your current numbers over to the new system. We ensure the transition is seamless so your customers never experience a gap in service or a change in how they reach you.

How is this priced?

Your price is a flat monthly price per user based on the specific features you choose to activate for your employees.
