Hi everyone! We're a construction company with roughly 17–20 users and need to replace our current phone system. Right now, callers mainly use extensions, and we get frequent complaints from clients who don't want to wait around to reach the right person. We'd like better call routing, an auto-attendant or phone tree, queues, voicemail, and an easy way to direct callers quickly.
Some employees only receive calls a couple of times per year, so we're trying to avoid an expensive per-user system with lots of unnecessary licenses. We also don't want a complicated deployment that requires everyone to install and learn heavy apps. Ideally, we're looking for something simple, reliable, reasonably priced, and painless to manage.

Before replacing everything, check whether your existing system can be reconfigured. Most business phone systems support auto-attendants, business-hours routing, overflow groups, queues, and voicemail, even if you’ve only been using basic extensions. A local phone provider or MSP could redesign the call flow without forcing a full replacement.
If keeping recurring costs low is more important than having a fully managed cloud service, FreePBX, PBXact, or Yeastar are worth considering. They can run on an on-premises appliance or a small cloud server and provide plenty of call-routing features. The tradeoff is that you’ll be responsible for updates, backups, security, and troubleshooting.
Zoom Phone is another strong fit for a small office. It’s straightforward to configure, supports phone trees and call handling, and users can take calls through a desktop app, mobile app, or regular VoIP handsets. It’s commonly priced around the same range as other cloud systems and tends to be simple for non-specialists to use.
We’ve used it for several years and migration was smooth. For a business this size, you can give direct numbers to key staff while keeping less frequently contacted employees behind extensions.
If you already use Microsoft 365, Teams Phone is probably the easiest place to start. It gives you call routing, auto-attendants, queues, voicemail-to-email, and the ability to use desk phones, computers, or mobile devices. It’s also relatively easy to manage because users already have one login for everything.
The main concern is that a Microsoft outage can affect email, messaging, and phone service at the same time. It’s worth checking your internet and outage-contingency plans before committing.
For 17–20 users, I’d lean toward a cloud PBX such as Teams Phone or Zoom Phone unless you already have someone comfortable maintaining a self-hosted system. They’re quick to deploy, work from anywhere, and let you avoid buying desk phones for people who rarely receive calls.
Also compare Webex Calling, RingCentral, 8x8, and 3CX, but focus less on brand names and more on the exact features and licensing. Ask each provider to demonstrate your real call flow: greeting, department selection, direct extension dialing, after-hours handling, queues, overflow, and voicemail. That will expose whether the system is actually simple enough for your staff.
A hosted version avoids some office power and internet problems, but make sure you have a backup internet connection or call-forwarding plan. Cloud systems are easier operationally, but the monthly licensing can add up.
