Making calls locally and internationally is made possible with VoIP or Voice over Internet Protocol. It is a technology that allows you to conduct voice calls using a broadband internet connection instead of a regular phone line. VoIP providers help businesses make and receive high-quality calls and offer advanced features not usually available on landline service.

The VoIP market in the US is estimated to be worth $11.5 billion in 2023 (IBIS World, 2023). VoIP has especially been useful for businesses that have remote workers or multiple locations, as it allows for easy communication between them. VoIP providers offer a range of features, including video calling, SMS support, instant messaging, and integration with other business software, such as CRM (Customer Relationship Management) systems.

Our team at Research.com compiled statistics and trends related to the use of VoIP in various industries to give an overview of how businesses utilize this technology. We also listed our recommended VoIP providers that highlight the best features and pricing details. By the end of this guide, you will have a better understanding of VoIP and how it can benefit your business.

The adoption of VoIP in the US has been on the rise, and it offers numerous benefits, including cost savings, flexibility, and scalability. The rise of remote working, the popularity of cloud services, and advances in telecommunications infrastructure are some of the factors driving the growth of the VoIP market. Here are some relevant statistics on the use of VoIP:

The potential market growth for VoIP providers is significant, with a CAGR (Compound Annual Growth Rate) of 10% from 2023 to 2032 (Global Market Insights, 2023).
The telephone call center industry is projected to grow to as much as $21.8 billion in the US by 2024 (Statista, 2021).
In a survey among 1,059 consumers, 29% of millennials and 31% of Gen Z respondents prefer to use contacting brands by phone (Faria, 2023).

Customer service and after-sales support are important for businesses to retain customers. While utilizing artificial intelligence (AI) chatbots and automated replies have become prevalent, most customers prefer speaking to human customer service personnel to address their concerns. In a survey conducted in the US with 1,000 respondents, 85% of consumers stated that being able to speak to an actual person when contacting a business is very important for them (Faria, 2023). The use of VoIP lets businesses keep their contact center working efficiently through flexible communication channels and effective call routing.

However, businesses may face some challenges during VoIP deployment, including network readiness, ISP limitations, security, compatibility, and quality of service (QoS). Poor QoS can lead to dropped calls, echoes, delays, and other performance issues, which can affect the user experience. Companies need to invest in proper training and use the best cloud-based LMS to pass on knowledge and skills even to remote teams.

Several VoIP providers offer basic call features as well as team collaboration tools to use for corporate training and the like. There are also platforms with advanced capabilities such as call queuing and routing, automated greetings, and voicemail transcription. Some companies have additional fees for calls in certain locations. You can search “VoIP providers near me" to ensure that local call features are enabled and support is readily available.

Selecting the right VoIP provider is crucial for businesses aiming to streamline communication, reduce costs, and enhance collaboration. Here are key factors businesses should assess to ensure they choose the most suitable VoIP provider for their unique needs:

Many VoIP providers guarantee a specific uptime percentage, often 99.99%, which indicates their reliability. Consider providers with positive reviews and strong reputation in service stability.
Scalability and Flexibility: As businesses grow, they may need to add more lines, users, or features. Look for a VoIP provider that offers scalable plans allowing easy expansion or reduction in services, so businesses can adapt without needing a costly platform change.
Integration with Existing Tools: The VoIP system should integrate seamlessly with the business’s existing software, such as CRM platforms, project management tools, or customer service applications. This connectivity can streamline workflows, improve customer service, and provide valuable insights.

Pricing Structure: VoIP pricing varies widely, with options for per-user monthly plans, bundled packages, or pay-as-you-go models. Carefully review any hidden fees, setup costs, or call charges, especially for international calls, to find the most cost-effective option.

Security and Compliance: With increased concerns over data security, it’s critical that the VoIP provider offers robust security features like encryption, multi-factor authentication, and compliance with standards like GDPR or HIPAA, depending on industry requirements.
Trial Periods and Demos: Many VoIP providers offer trial periods or free demos, allowing businesses to test the software’s interface, usability, and key features. Utilizing a trial period is a good way to verify that the platform aligns with operational needs before committing.
