Zoom: Best Overall Free Conference Call Service & Easiest-to-use
*Monthly pricing per user. Save 17% with annual billing.
Zoom is the overall winner in the battle of the best free audio and video conference call services since it is easy to set up and use. Its browser-based services allow hassle-free access to meeting participants even without plugins or Zoom on their devices. The in-meeting tools, namely screen sharing, virtual backgrounds, and private and group chat, create a collaborative and interactive experience.
One drawback to using Zoom’s free plan, however, is there’s no cloud storage. Other providers like RingCentral feature cloud recordings in their free plan, with a retention period of up to seven (7) days. Another disadvantage is the absence of a telephone dial-in option. Unlike Zoom, Dialpad has this feature in its free plan.
Before adopting Zoom, become familiar with its features. Read our in-depth Zoom review to learn more about the platform.
- Co-annotation on screen share: Allow team members to draw and make notes on a shared screen. You simply have to click the Security button in the main menu and tick off the Annotate on Shared Content option.
- Remote desktop control: Take the hassle out of explaining to another team member where to put their mouse or what to type. Request and take control of their screen with this feature.
- Multi-share: Share screens simultaneously during a meeting. Use this when comparing files or materials as a team in real time.
Cisco Webex: Best for Global Teams
*The Meet plan has both monthly and annual billing options.
Cisco Webex is ideal for remote and global teams that need high-quality video meetings. It has a global network of data centers, making it possible for team members anywhere in the world to access crisp, high-definition videos without delays. Another factor that makes Cisco Webex a great option for remote teams is its range of collaboration tools.
The free conference calling service allows businesses to send unlimited messages and share files during sessions. Make conversations interactive by using reactions, emojis, and GIFs. Brainstorming is easier as well with screen sharing, breakout rooms, raise hand functions, and polling. This is the reason this platform also made it to our list of the best conference call services.
Similar to Zoom, the phone dial-in option isn’t available in Cisco Webex free version. Another drawback is that you have to get a subscription to unlock the alternate host option. If this admin control feature is important to you in managing remote team meetings, consider upgrading to a paid plan. Read our comprehensive Cisco Webex review to learn about the other perks you’ll get.
Cisco Webex Features
- Video messaging: Rather than typing out instructions to team members, use this feature to capture a clear demo of the work you want them to do.
- Hand gestures recognition: Cisco Webex turns non-verbal gestures, like claps and thumbs-up, into animated images displayed on your thumbnail. While making the meeting interactive and fun, this also facilitates a more efficient meeting, as the system captures raised hands, allowing team members to get noticed without disrupting the flow of the conversation.
- Interactive whiteboarding: Put your team’s ideas on a digital canvas. The whiteboard features a pointer, drag/move option, pen tool, magic pen, eraser, and stickies, which make brainstorming sessions more collaborative.
RingCentral Video: Best for Secure Meetings
*Monthly pricing per user. Save up to 33% with annual billing.
RingCentral Video is another strong contender in the list of best conference call services with free services, as it packs plenty of security features, helping businesses protect sensitive data. Aside from the usual admin controls, like meeting passwords and waiting rooms, the software is HITRUST (Health Information Trust Alliance)-certified, HIPAA- (Health Insurance Portability and Accountability Act of 1996), and BAA- (business associate agreement) compliant.
The certification from HITRUST guarantees that RingCentral Video follows the Common Security Framework (CSF), a framework used by top healthcare organizations and providers. Meanwhile, compliance with HIPAA-BAA reassures businesses that sensitive patient health information is secure.
Plus, RingCentral Video has International Organization for Standardization (ISO) 27001, ISO 27017, and ISO 27018 certifications, which ensure data privacy and security on cloud services. The free phone conferencing plan includes cloud recordings of up to 10 hours with a seven-day retention period.
RingCentral Video Features
- Host controls: Secure meetings and keep unauthorized individuals out with the lock meeting option. To avoid unnecessary interruptions during presentations, use the mute all functionality.
- Encrypted cloud recordings: Have peace of mind that your meeting recordings are secure online. Since they’re on the cloud, they’re also easily accessible to team members regardless of location.
- Team events: Create events and share them with your team. With this, you won’t have to forget to plot in a calendar the upcoming activities discussed in your meeting.
Google Meet: Best for Google Workspace Users
*Monthly pricing per user.
If you’re a longtime user of Google Workspace, you’ll find Google Meet is the best free conference call number service provider—integrating seamlessly with your productivity and collaboration tools. It allows you to schedule a session in Google Calendar directly, eliminating the need to send separate reminders to your team.
From any Google Doc, document, spreadsheet, or slide, you’re able to hop on a video call easily since the Google Meet option is readily available within the GDoc interface. This is especially helpful when you want to present to colleagues a specific document you’re working on.
On top of that, Google Drive hosts the recordings of Google Meet sessions. It’s easy to retrieve files and share with colleagues what transpired in meetings since the recordings are already on your storage service. Learn more about the features of this platform in our Google Meet review.
The only drawback in choosing Meet is that it’s limited in collaboration tools. Its free version doesn’t have breakout rooms and a private messaging option. If these functionalities are essential in running successful meetings in your business, it’s best to opt for RingCentral or Cisco Webex for a feature-rich conferencing solution.
Google Meet Features
- Picture-in-picture mode: Switch to different browser tabs and keep the Google Meet window visible. This feature that enables multitasking is available on Google Chrome.
- Automated captions in English: Google’s speech-to-text technology makes live captioning possible, helping meeting participants with disabilities to follow along with the discussion. The free plan only includes English captions.
- Whiteboard add-on: Google Meet uses the third-party whiteboarding application, Miro. Using the pre-built templates provided, create journey maps or brainstorming diagrams when collaborating with team members.
FreeConferenceCall.com: Best for Large Meetings
Among the vendors mentioned here, FreeConferenceCall.com is the best toll-free conference call service provider that accommodates the most number of participants in its free plan. It allows up to 1,000 users in one meeting, which is significantly larger than what other providers offer in their free versions. Zoom, Cisco Webex, RingCentral Video, and Google Meet only allow up to 100 participants.
Further improving access to meeting participants, FreeConferenceCall.com has domestic and international dial-in numbers. This makes the platform one of the best free international conference call services, providing language support for select countries. Plus, the conferencing tool features radio streaming, helping businesses reach a larger audience.
- Meeting Wall: Create a dedicated webpage for your meetings, providing the link participants should click to access the session. The Meeting Wall also features meeting resources, which allow you to upload any materials participants must download before or after your conference.
- Studio Presentation: Make a presentation by recording your screen with audio. Share a link to the recording on your Meeting Wall.
- Call detail reports: Receive a report in your inbox after every meeting. Important details included in these reports are the number of participants, the start and end time of the meeting, and the duration.
Phone.com: Best for Team- or Purpose-specific Meetings
*Monthly pricing per user. Save 20% with annual billing.
Phone.com is one of the best free phone conference call services, offering a conference bridge number on each extension on your account without charge. A conference bridge makes it easy to set up different virtual spaces for specific purposes. For example, you get to give each of your sales representatives their own conference bridge, dedicated to helping them connect with leads. Create dedicated rooms for other teams, from marketing to customer support.
Do note, however, that while the conference bridge number is free, the actual plans offered are not, and they are quite expensive for the features they provide. For instance, the Basic plan, which costs $14.99, only accommodates 10 video meeting participants (although it comes with a broad range of voice features).
In comparison, for the same price, RingCentral Video’s Pro+ plan hosts up to 200 participants with cloud recording of up to 100 hours and a one-year retention period. It also comes with a wide array of third-party integrations and developer APIs.

Dialpad Meetings: Best for Productivity & Collaboration Integrations
*Annual billing option is available.

One tool you can connect to this platform is Google Calendar. View your schedule for the day and go straight to your meeting without ever leaving Dialpad. If you’re using Microsoft Outlook, add in Dialpad to easily include meetings on emails and calendar invites.
For teams that heavily rely on Salesforce, set up Dialpad on your customer relationship management (CRM) platform by enabling it in the app manager. With the video conferencing solution readily available on your CRM tool, it’s easy to schedule a conference with a contact or lead.
Other integrations Dialpad offers include HubSpot, Intercom, Slack, Microsoft Teams, Evernote, Miro, LinkedIn, and Twitter. For its telephone dial-in option, the platform also makes for the best free conference call number service providers in the market today. If you want to learn more about this tool’s features, read our comprehensive Dialpad Meetings review.
While the conferencing solution offers several useful integrations, you’ll be limited to only 10 meeting participants in the free version. Even the paid plan accommodates 150 attendees only, fewer compared to other providers. Google Meet’s Business Plus, which is $18 a month per user (cheaper than Dialpad’s Business plan by $2), already accommodates 500 participants. If you host large teams in meetings and want a free solution, go for FreeConferenceCall.com.
