Cloud or Premise Based Phone System

It's time to invest in a new phone system but you're standing at the crossroads wondering what's right for your business.

Updated October 2026

Here is how we help customers decide between a cloud and a premise-based phone system.

Which Is Better for Small and Mid-Sized Companies?

Cloud phone systems are usually the better fit for small and mid-sized companies because of their flexibility, easy growth, and lower upfront cost. They work especially well for businesses with remote or spread-out teams, since employees can work from anywhere.

Premise-based systems, also called a PBX (private branch exchange), can make more sense for businesses that want full control of their phone system and already have the equipment and wiring in place.

The right choice depends on your business needs, budget, and long-term goals. If flexibility and easy management matter most, a cloud system is likely the better option. If control and getting the most out of equipment you already own matter more, a premise-based system may be the way to go.

When We Recommend a Cloud Phone System

• Moving into a new location. Start fresh and cable the building with Cat6 or better so it can handle gigabit speeds. You can also save on cabling, because a cloud desk phone and computer can share one cable run instead of the two runs often needed with a PBX.
• Adding a door phone or entry system. Pair your phones with a door phone and key fob entry, which keeps a record of who comes and goes. Staff can use affordable video phones to see who is at the door before buzzing them in.
• Adding IP paging. Integrate an IP paging system with your cloud phones and use different tones for breaks or announcements.
• Supporting remote staff. Mobile and desktop apps let employees use their office extension from anywhere.

When We Recommend Keeping a Premise-Based System

• Older building wiring. If your building has basic Cat5 cable and Cat3 for voice, and rewiring isn't in the budget, a premise-based system can keep working on that wiring. Cloud phones work best on Cat5e or better.
• An existing paging system. If you have older paging equipment that your Avaya IP Office already connects to, keeping the PBX can save you from replacing it.
• Lowering your monthly bill. Pair your Avaya IP Office with TTI SIP 500 trunks to help reduce monthly phone line costs.
