Unified Communications
A phone system your customers can actually reach.
Many businesses still run phone systems that were chosen a decade ago and patched since. We help you understand what modern cloud communications can do for call handling, remote staff and multi-location routing, and compare suppliers against your real requirements.
What to evaluate
Unified Communications, in practical terms.
- Cloud business phone systems
- UCaaS platforms
- Hosted voice
- Video and collaboration
- Microsoft Teams calling options where supported by suppliers
- Business SMS and messaging
- Call recording and analytics
The right fit
Who should consider it?
- Businesses with remote or hybrid teams
- Multi-location companies routing calls between sites
- Organizations replacing aging on-premises phone systems
- Teams already standardized on Microsoft 365
Business objectives
What a well-scoped solution can support.
- One system across every location
- Calls routed to the right person or team
- Staff can work from anywhere
- Clear reporting on call volume and missed calls
These are evaluation objectives, not promised results. Scope and performance depend on supplier agreements and implementation.
Compare before committing
Alternatives & tradeoffs
| Approach | Often best for | What to consider |
|---|---|---|
| UCaaS platform | Most businesses wanting phone, video and messaging together | Depends on reliable internet; migration of numbers needs planning |
| Teams calling | Organizations living in Microsoft 365 | Licensing and calling-plan structure vary; not every feature matches a dedicated phone platform |
| Hosted voice only | Simple phone replacement | Fewer collaboration features |

Frequently asked questions
What is the difference between UCaaS and CCaaS?
UCaaS (Unified Communications as a Service) is the internal communication system for employees: phones, video meetings and messaging. CCaaS (Contact Center as a Service) is built for handling high volumes of customer interactions, with queues, skills-based routing, workforce management and analytics. Many businesses need UCaaS; businesses with teams dedicated to answering customers often need both.
Can we keep our existing phone numbers?
In most cases, yes. Numbers are moved through a porting process. The timeline depends on the current carrier and the number of lines, so porting should be planned before a cutover date is set.
Is a cloud phone system reliable?
Reliability depends heavily on the internet connection at each site and the supplier's architecture. That is why phone decisions should be made alongside connectivity decisions, including backup internet for critical locations.
