What Is a Conference Call Service?
Conference call services are communication platforms that enable multiple participants to join a single audio or video conversation simultaneously. These services have evolved from traditional phone systems to sophisticated internet-powered solutions.
Modern conference call services typically offer:
- Audio and video capabilities
- Screen sharing and presentation tools
- Chat features
- Recording and transcription options
- Integration with other business software
These platforms use Voice over Internet Protocol (VoIP) technology to make calls over the internet. The shift to conference calling has dramatically improved accessibility, reduced costs, and expanded feature sets compared to traditional phone systems.
Conference call services cater to various business needs, from small team meetings to large-scale webinars, and are indispensable tools for remote collaboration, client communications, and virtual events.
Must-Have Features for Effective Conference Calling
Plenty of video meeting platforms offer a wide range of functionality, from basic to advanced features. Regardless of which platform you choose, ensure that it offers the following essential conference call features.
- Screen sharing and collaboration: Conduct interactive online meetings by sharing screens and using virtual whiteboards and drawing tools for brainstorming and annotating ideas.
- Recording and transcription options: Capture valuable discussions for future reference and ensure inclusivity for team members who prefer summaries of calls and written content.
- Dial-in numbers: Provide flexibility for participants with limited internet access or those who prefer joining by phone.
- Breakout rooms: Facilitate smaller group discussions within large conferences, ideal for focused brainstorming or team projects.
- Enhanced audio and video features: Look for noise cancellation, high-definition video, and virtual backgrounds for a professional conferencing experience.
What to Look for in a Conference Call Service
Many conference call solutions come from business phone providers, especially if you’re looking for high-quality call and video conferencing options with strong reliability and consistent performance.
When choosing a conference call provider, look for a solution with the following 10 qualities.
📈 Scalability for large teams
Scalability is essential when choosing a conference call provider. You want a tool that supports a large number of participants in a single call, catering to the current size and potential expansion of your business.
Keep in mind that many conferencing solutions — for video and audio calls — may struggle to support a large number of participants. Choose a business plan that allows for the number of callers you need and actually supports them when you host conference calls.
Consider future growth as well – a solution that can accommodate your needs now and scale up as your business expands is ideal.
✅ Reliability and performance
When it comes to conference calls, nothing is more frustrating than poor audio quality or dropped connections. Look for a provider that offers stable, consistent audio and video quality with minimal latency.
Don’t just take their word for it — check customer reviews to get a real sense of the service’s performance. Remember, reliability is key to ensuring smooth, effective communication.
Also, check for published uptime statistics and service level agreements (SLAs).
🔏 Security & encryption
Every conference line should be secure so no one else can listen in. Choose a conferencing solution that offers strong data encryption and security measures to protect sensitive corporate and customer information.
Ideally, look for the following features:
- Security standards such as those included in ISO/IEC 27001
- End-to-end encryption on relevant features, such as SMS messaging
- Protected transmissions with Transport Layer Security and Secure Real-Time Transport Protocol encryption
- Password protection for meetings
- Waiting rooms to control participant entry
- Hosts to remove participants if needed
♻️ Strong integration ecosystem
A strong integration system will give more functionality to your conferencing tool of choice.
Seamless integrations with your existing tech stack and cloud systems are essential, so look for a tool that works with the business tools and systems you’re already using, including the following:
- CRMs, such as HubSpot or Salesforce
- Google Workspace, along with tools such as Google Calendar
- Email software, such as Microsoft Outlook
- Project management software, such as Asana
- Collaboration tools like Slack or Microsoft Teams
- Calendar apps for easy scheduling and reminders
🤙🏻 User-friendliness for all skill levels
Not all employees are naturally tech-savvy, so it’s essential to have a user-friendly audio and video conference tool that is easy for managers, employees, and executives to use.
While you should offer training, the goal is to minimize the time spent on implementing the new tool and ensure that everyone can use it without issues.
Look for features like one-click meeting joins, easy screen sharing, and intuitive meeting controls.
Strike a balance between the number of features a tool has and the complexity of the interface. The tool should have as many features as possible while providing basic features, such as making a simple call, but it should also have an intuitive interface that won’t overwhelm anyone.
📞 Responsive customer support
Reliable and responsive customer service is a must for any tool your business relies on.
A provider’s customer service should ideally meet these standards:
- Available 24/7 via email, online chat, and phone
- Capable of troubleshooting and offering technical assistance
- Proven track record of happy customers with resolved issues
- Offer comprehensive documentation and knowledge bases
- Provide regular updates and communicate about service changes or improvements
🖍 Customization options
Every business has unique needs when it comes to conference solutions, so there’s no perfect one-size-fits-all solution.
The ability to tailor your service to your specific business needs and preferences should be a priority. Find a tool that supports your desired number of call participants, meeting time limits, collaboration features, and pricing.
At the most basic, your conference calling system should let you customize virtual backgrounds, brand your meeting rooms with company logos, set up recurring meetings with saved preferences, and create custom meeting templates for different types of calls
💰 Cost-effectiveness
There are plenty of outstanding conferencing solutions on the market, but they aren’t all within your budget.
Consider the cost and pricing models of different tools. One platform may seem appealing at $15 per month, with solid features and unlimited meetings included, until you realize the price only covers five callers.
When assessing cost-effectiveness, consider the total cost of each plan by looking at different cost factors.
🌎 Global accessibility
The ability to have secure and stable conference lines with employees, vendors, and clients all over the world has never been more important.
Make sure that the tool you choose provides access to multilingual customer support and can connect global locations with ease, even if your business is located within the U.S.
Consider features like:
- International dial-in numbers
- Support for multiple time zones
- Real-time language translation options
- The ability to host meetings in different countries without significant quality loss
🪜Cross-platform and cross-device compatibility
While people love debating the benefits of iOS vs. Android, you don’t want to pick a conferencing tool that only works on one or the other.
Ensure ease of use by choosing a conferencing solution that works on both iOS and Android, as well as on multiple web browsers and mobile devices. Conference bridge lines are a perfect way to ensure everyone can dial into your next conference call.
Choosing the Right Conference Call Service Provider
Here are a few more tips to close out on choosing the right conference call provider.
- Number of participants: Different services cater to different group sizes. Consider the average number of participants in your typical meetings.
- Features needed: Identify the features that are most important for your team, such as screen sharing, recording, or international calling.
- Pricing plans: Compare different providers’ pricing plans to find one that fits your budget. Many services offer freemium plans for small teams, while subscription and enterprise plans cater to larger organizations.
- Ease of use: Choose a service with a user-friendly interface that allows your team to easily access and utilize conference call features.
While features are important, consider your company culture and employee comfort level. Opt for a service that aligns with your team’s technical proficiency and provides adequate training materials. A good practice is to evaluate free demos before committing to a paid plan.
How Much Does a Conference Calling Service Cost?
Paid conference call services cost between $12 and $50 per user per month, billed annually. Entry-level plans support 100 to 300 participants with standard video and audio features. Higher-end plans are more expensive and offer advanced tools, larger conference capacity, and priority support.
Here are the different factors that influence pricing:
- Number of participants per meeting
- Meeting duration limits (some free plans cap at 40 minutes)
- Access to extras like recording, transcription, breakout rooms, and analytics
- Security features, including encryption and password protection
- 24/7 customer support or dedicated account managers
- Integrations with CRMs, calendars, and collaboration tools
- International dial-in and time zone support
Many platforms offer free or freemium plans for individuals or small teams. These come with participant limits, shorter meeting times, and restricted access to premium features.
When choosing a conferencing plan, review both the monthly cost and what’s included. Consider participant capacity, meeting limits, feature availability, and extra charges for international access. This way, you can make sure the service meets your current and growing needs.
