A cloud-based phone system hosts your business’s calling platform with a service provider instead of relying on a telephone controller installed in your building. Employees can make and receive business calls through compatible desk phones, computer applications, or mobile apps.
For businesses considering an upgrade, the appeal is practical: easier call routing, support for remote employees, and the ability to connect multiple locations. A successful switch still requires planning for your internet connection, network, phone numbers, and existing equipment.
North Shore Technologies helps Northeast Ohio businesses evaluate their options and plan the installation work needed for a reliable transition.
How Does a Cloud Phone System Work?
When someone calls your business number, the provider’s hosted platform directs the call according to your configured rules. It might ring the receptionist, play a menu, send the caller to a department, or route the call to voicemail after hours.
Your employees connect to that platform using supported devices and an internet connection.
A typical setup includes:
- Cloud phone service: The provider hosts and manages the calling platform.
- Phones or applications: Employees use compatible desk phones, desktop apps, or mobile apps.
- Office network: Your router, switches, cabling, and internet connection support on-site calling.
- Call handling settings: Greetings, extensions, ring groups, voicemail, and business hours determine where calls go.
Providers such as Nextiva offer desk-phone and application-based calling. Available features depend on the selected service plan and supported equipment.
Is a Cloud Phone System the Same as VoIP?
They are related, but the terms describe different things.
VoIP—Voice over Internet Protocol—is the technology used to carry voice over an IP network. A cloud phone system uses VoIP while hosting the calling platform with a provider.
An on-premises phone system can also use VoIP. The main distinction is where the platform operates and who manages it.
| Consideration | Cloud phone system | On-premises phone system |
|---|---|---|
| Calling platform | Hosted by the provider | Located at your business |
| Administration | Usually through an online portal | Depends on the installed platform |
| Remote users | Often supported through apps and compatible phones | Depends on system capabilities and configuration |
| Costs | Recurring service charges plus deployment costs | Equipment, licensing, carrier service, and support costs |
| Maintenance | Provider manages the hosted platform; local equipment still needs support | On-site equipment and software require maintenance |

When Does a Cloud Phone System Make Sense?
Cloud phones are worth evaluating when your business needs to:
- Replace an aging phone system.
- Connect employees across multiple locations.
- Support remote or hybrid staff.
- Improve reception coverage and overflow call handling.
- Add or change users more easily.
- Manage greetings, schedules, and voicemail more consistently.
An office might need calls to ring reception first, then an overflow group. A multi-location organization might want extension dialing between sites while retaining separate local numbers.
The starting point should be how your organization handles calls—not simply a list of available features.
Considering a switch? Tell NST your approximate user count, locations, current system, and main concerns. We can help identify the information needed for a preliminary budget.
What Should You Check Before Switching?
Internet and Network Readiness
Call quality depends on more than download speed. Connection stability, network congestion, equipment configuration, and wireless coverage can affect the calling experience.
Before installation, review:
- Internet reliability and available capacity.
- Router and firewall compatibility.
- Network switch capacity and available ports.
- Power over Ethernet requirements for desk phones.
- Existing cabling condition.
- Wi-Fi coverage if wireless phones or apps will be used.
- Backup power and continuity options.
A new service subscription will not resolve damaged cabling or poorly configured network equipment. NST can evaluate related business phone system and network installation requirements.
Phone Numbers and Porting
Many businesses can transfer their existing numbers to a new provider through number porting. Eligibility, account information, and timing need to be confirmed.
Create a complete list of numbers, including main lines, direct numbers, fax numbers, and numbers associated with other services.
Keep existing service active until the provider confirms the transfer and the required calling functions have been tested. Also review bundled services before canceling anything, because changes may affect your internet package or other account charges.
Existing Phones and Specialty Equipment
Do not assume every existing device will work with the new platform.
Older digital desk phones may need replacement. Some analog devices may work through a compatible adapter or gateway, but each application requires review.
Identify equipment such as:
- Fax machines.
- Overhead paging systems.
- Door phones and intercoms.
- Alarm communicators.
- Elevator phones.
- Other specialty telephone connections.
Life-safety connections require separate compatibility and requirements review with the responsible provider or contractor.
Call Flow and Support Responsibilities
Document who answers calls, what happens when staff are busy, and where calls should go after hours.
Also establish who handles:
- Provider account and service issues.
- User and call-routing changes.
- Desk phones and local network equipment.
- Installation, training, and on-site troubleshooting.
Clear responsibilities make it easier to get help when an issue occurs. Confirm support hours and response arrangements before selecting a solution.

What Does a Cloud Phone System Cost?
Evaluate both recurring service costs and the cost of deploying the system.
| Cost category | Items to review |
|---|---|
| Recurring service | Users, shared-phone licensing, service plans, optional features, taxes, and fees |
| Phones and accessories | Desk phones, headsets, cordless equipment, and adapters |
| Network preparation | Cabling, PoE switches, router changes, and backup power |
| Deployment | Setup, call-flow configuration, installation, testing, training, and cutover |
| Ongoing assistance | Support arrangements and future changes |
A low advertised monthly price may exclude work needed at your building. Conversely, some organizations can reuse suitable equipment and reduce deployment costs.
Compare proposals using the same user count, devices, features, installation scope, and support responsibilities. Avoid assuming that switching automatically reduces your total bill.
What Happens if the Office Loses Internet or Power?
Office desk phones generally depend on both working network equipment and internet access. An outage can interrupt calling from those devices.
Depending on the platform and configuration, employees may still be able to use mobile apps over cellular data or receive calls through an alternate routing arrangement. These options should be configured and tested in advance.
Backup power can help keep local equipment running during a power interruption, but it does not replace a failed internet connection.

Frequently Asked Questions
Can we keep our business phone number?
Often, yes. The new provider must confirm that the number can be transferred and verify the required account details. Keep existing service active through the agreed transfer and testing process.
Does every employee need a desk phone?
No. Depending on the platform and their role, employees may use a desk phone, computer application, or mobile app. Reception and shared work areas may have different requirements from remote staff.
Will we need new cabling?
Not necessarily. Suitable existing network cabling may be reusable. Its condition, location, available ports, and power requirements should be checked before installation.
Can cloud phones connect to overhead paging?
Some platforms support paging through compatible equipment. The existing amplifier, interface, and required paging functions need to be reviewed before selecting the connection method.
Plan Your Cloud Phone Upgrade
If you are replacing an older system or exploring cloud phones, start with your current system, approximate user count, locations, and the call-handling problems you want to solve.
