RingCentral
Cloud phone system with texting, fax, video meetings and team chat
Which one is for you
Pick CallTower if
- Fits if your company already runs on Teams, Webex or Zoom
- Works for IT partners who resell business phone service
Look elsewhere if
- Skip it if you want a posted price, as quotes go through sales
- Watch out: the Teams, Webex or Zoom licenses are a separate cost
- Not for you if you want a standalone phone system, as it adds calling to other platforms
- Tight if you want to buy direct, as the listing shows it sells largely through resellers
Pick RingCentral if
- Fits if you want calls, fax, meetings and chat from one company on one bill
- Works for Microsoft Teams shops that want RingCentral calling inside Teams
Look elsewhere if
- Tight if you text customers a lot, with 25 texts a person a month on Core
- Pricey if you add the extras: AI Receptionist from $39, SMS Booster $25, Call Queues Booster $35
- Not for you if you want to try texting first, since it isn't in the free trial
- Tight if you want calls recorded automatically or logged in a CRM, as both need Advanced at $25
- Watch out: listed prices are for 1-5 users, they change for 6-100, and texting needs TCR registration that may carry fees
How we grade them
| 1.8GPACallTowerWeak | 3.0GPARingCentralVery good | |
|---|---|---|
| Value for money | CNo pricing published; it goes through sales or channel partners. | C$20 a head for a team of five on Core, billed yearly ($30 monthly), which is the price for 1-5 users. That's just past this category's dearer quarter ($19.99), so middle of the road. Automatic recording and CRM links need Advanced at $25. |
| Free plan and trial | FNo free plan and no free trial is offered on the pages we read. | CA 14-day free trial for new subscribers, with texting left out of it. No free plan, and the listing doesn't say whether the trial needs a card. |
| Features | CCalling for Teams, Webex and Zoom, voice add-ons, texting, faxing and contact center platforms. It needs those platforms' own licenses. | BUnlimited US and Canada calls, phone menus, call queues, fax, 300-person video meetings, team chat and an AI assistant for call notes. That's the whole phone job, though Core's 25 texts a person a month is stingy. |
| Ease of use | CNo store rating on record. It's sold through sales and partners. | A4.83 from about 78,000 App Store ratings, above the 4.7 from 1,000 ratings that an A needs. |
| Platforms and integrations | BWeb, with Teams, Webex, Zoom, Five9 and Genesys Cloud. | AWeb, Mac, Windows, iPhone and Android, with Salesforce, HubSpot, Zendesk, ServiceNow, Microsoft Teams, Google Workspace and Slack on the integrations list. |
| Best for | business calling for Teams, Webex and Zoom | calls, texts, fax and meetings in one app |

More comparisons
How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
