9 Key VoIP Trends to Watch in 2024

Voice over Internet Protocol, or VoIP, has revolutionized business communications over the past decade. By enabling voice calls to be made over the internet instead of traditional phone lines, VoIP provides greater flexibility, scalability and cost efficiency compared to legacy telephony.

VoIP adoption has skyrocketed in recent years, with the global market size expected to reach $55 billion by 2025, according to Global Market Insights. And the technology continues to evolve rapidly, with new capabilities and use cases emerging all the time.

As we look ahead to 2024, here are 9 key VoIP trends that every business should have on their radar:

1. Continued Growth of VoIP Adoption Among SMBs

While enterprises were among the earliest adopters of VoIP, small and mid-size businesses are quickly catching up. The cost savings, flexibility and rich feature sets of cloud-based VoIP solutions make it an increasingly appealing option for SMBs.

In a survey by Software Advice, over 70% of small businesses said they were likely to invest in a new VoIP system within the next few years. And Gartner projects that by 2024, 74% of SMBs will have fully adopted VoIP.

VoIP providers are responding to this demand with solutions tailored for the needs and budgets of smaller organizations. Offerings like Ooma Office, Grasshopper and Phone.com provide robust VoIP functionality without the complexity and cost of enterprise-grade solutions.

2. AI-Powered Automation of Incoming Calls and Messages

Artificial intelligence is one of the most transformative forces in business today, and its impact is being felt across the VoIP landscape. By 2024, AI-powered capabilities like natural language processing and machine learning will enable VoIP systems to automatically classify, route and respond to incoming calls and messages with minimal human intervention.

For example, AI can determine the reason for a customer‘s call based on their spoken request or their history of interactions, and immediately direct them to the appropriate department or agent. It can transcribe voicemails and extract key details to generate tickets or tasks. And it can provide agents with real-time guidance on how to most effectively address customer inquiries.

Several VoIP providers are already leveraging AI and machine learning to power smarter call experiences. Dialpad‘s VoiceAI technology uses natural language processing to provide real-time coaching and automation. And TalkIQ, which was acquired by Dialpad in 2018, can analyze voice data to glean customer sentiment and provide actionable insights.

3. Deeper Integration of VoIP Data with CRM and Business Systems

To deliver true business value, a VoIP solution can‘t operate in a silo – it needs to integrate seamlessly with an organization‘s CRM platform and other mission-critical systems. Linking interactions that occur through the VoIP system with customer records and transaction histories provides a more holistic view of the customer journey.

Expect to see tighter coupling of VoIP and CRM as a major trend in the coming years. According to Deloitte‘s Tech Trends 2020 report, "CRM remains the single largest and fastest growing enterprise application category," and a key focus will be using APIs to "seamlessly connect processes and data" between CRM and adjacent systems such as VoIP.

Leading VoIP providers already offer out-of-the-box integrations with popular CRM platforms like Salesforce, HubSpot and Microsoft Dynamics. These integrations automatically log call activity to contact records, enable click-to-call from within the CRM interface, and sync data bidirectionally to ensure consistent information across systems.

Investing the time to set up these integrations and create consistent workflows between VoIP and CRM will pay major dividends in the form of more complete customer intelligence and improved agent productivity. According to a Forrester study, tight CRM integration is one of the key value drivers of VoIP and can increase organization sales by up to 12%.

4. Wider Availability of AI-Based Fraud Detection

While the rise of VoIP has introduced new opportunities for businesses, it has unfortunately also opened the door to sophisticated fraud schemes and attacks. In 2019, a major vulnerability in WhatsApp‘s VoIP stack was exploited to inject spyware on users‘ devices simply by placing a call, even if the call wasn‘t answered.

To combat the growing threat of fraud and hacking, expect to see wider adoption of AI-powered security solutions for VoIP. Many large enterprises are already using advanced AI tools that can detect fraud attempts in real-time based on acoustic factors, metadata and other signals.

Pindrop‘s Deep Voice biometric engine, for example, can analyze over 250 factors of a caller‘s voice to identify potential fraud with 99% certainty. And Nuance‘s AI-powered fraud prevention solution already protects billions of transactions annually for Fortune 500 companies.

While these enterprise-grade AI security tools can be cost-prohibitive for smaller organizations, look for the underlying technologies to become more accessible over the next few years. Cloud-based AI services from providers like Amazon and Google will make it easier for VoIP platforms to implement fraud detection and prevention capabilities into their offerings.

5. Enhanced Multi-Layer Security to Combat Vulnerabilities

In addition to AI-powered fraud detection, VoIP providers are beefing up security on multiple fronts to stay ahead of emerging threats and vulnerabilities. With the massive surge in remote work due to COVID-19, securing VoIP traffic over home networks and personal devices has become a major focus.

Some of the key security measures being implemented include:

• Encryption of all voice traffic, both in transit and at rest
• Multi-factor authentication to prevent unauthorized access to accounts
• Regular security audits and penetration testing to identify vulnerabilities
• Automated patch management to ensure systems stay up-to-date
• Segmentation of voice and data traffic on separate VLANs
• Secure access service edge (SASE) tools to protect remote workers

Leading providers like RingCentral, 8×8 and Vonage have made major investments in hardening their platforms and are transparent in communicating their security practices. Vonage, for example, publishes an annual Voice Traffic Security Report to provide visibility into emerging threats and the steps it‘s taking to combat fraud and abuse.

6. AI-Powered Language Detection and Routing

For companies that do business globally, providing support in a customer‘s native language is becoming table stakes. But hiring dedicated agents for every language isn‘t always practical or cost-effective.

AI-powered language detection capabilities enable VoIP systems to automatically identify the language spoken by a caller and route them to an appropriate agent resource. The AI models are trained on massive data sets of recorded speech to accurately classify languages in real-time.

Solutions like Intelligent IP‘s ipipi suite can detect and route calls in over 70 languages with greater than 90% accuracy. And Google‘s Cloud Speech API supports 120 languages and variants to provide coverage for a substantial portion of the world‘s population.

Expect to see language recognition become a standard feature of VoIP offerings targeting the enterprise segment. It will be a key differentiator for CX leaders tasked with supporting an increasingly global customer base.

7. VoIP as Part of an Integrated Omnichannel Strategy

While voice remains a critical communication channel, digital channels like email, chat and messaging are becoming the preferred starting point for most customer journeys. According to NICE InContact‘s 2020 Customer Experience Trends Report, 64% of consumers start their customer service interactions online, and 90% find it important to be able to communicate digitally with a company.

To provide a seamless and cohesive experience across these touchpoints, organizations will need to take an integrated omnichannel approach to customer engagement. And VoIP will play a key role as the bridge between digital and voice-based interactions.

Leading contact center and unified communications platforms have already evolved into true omnichannel solutions, with VoIP tightly woven into their UC stacks. Providers like Five9, NICE inContact, Talkdesk and Vonage offer "voice as an app" that enables agents to shift seamlessly between channels within a single interface.

This tight coupling of VoIP and digital channels will become increasingly important as customer journeys grow more complex. According to Dimension Data, over 35% of organizations have seen an increase in interactions that span across multiple channels. An integrated VoIP and digital approach will be key to providing the connected, personalized experiences that customers expect.

8. More Innovative Uses of VoIP APIs

As a software-powered technology, VoIP is ripe for innovation and extension through APIs and integrations. By exposing key telephony functions like voice, messaging and meetings through web services, VoIP platforms become more than just isolated systems – they can serve as the building blocks for all kinds of creative communication workflows.

Use cases are limited only by developers‘ imagination, and the coming years will see an explosion of new mashups and product experiences built around VoIP APIs. Some interesting examples that have already emerged include:

• Connecting VoIP and IoT systems to enable voice control of smart devices
• Sending automated voice alerts triggered by business events like system outages or stock price swings
• Enabling video communication within any web or mobile app via WebRTC
• Applying real-time sentiment analysis to sales and support calls
• Integrating team messaging and file sharing into VoIP softphones

Providers like Vonage, Twilio and RingCentral have doubled down on APIs and developer platforms to court this community of makers and spur innovation around their offerings. As these ecosystems grow and mature, look for APIs to extend the reach of VoIP into every corner of the enterprise.

9. VoIP as a Core Component of Enterprise Tech Stacks

Perhaps more than any other trend on this list, the shift of VoIP from a standalone tool to an integral part of the business technology fabric will have the biggest impact in the years ahead. Organizations are increasingly moving away from monolithic suite products in favor of best-of-breed solutions that are deeply integrated to work together as a cohesive whole.

For most companies, the core of this modern technology stack will be their CRM, collaboration, and VoIP/UC platforms. According to research from Citi Blog Equities, a majority of digital leaders have already "segregated their communication stack (60%) into ‘best-of-breed‘ vendors and plan on doing so at an increased rate (76%)."

When evaluating VoIP solutions, IT decision makers will need to look beyond features and consider how well the tool plays with the rest of their tech ecosystem. Does it offer open APIs and pre-built integrations with adjacent systems? Does it fit into broader vendor standardization efforts (e.g. Microsoft- or Cisco-centric environments)? Is it aligned with the company‘s cloud migration strategy?

Answering these questions will be key to choosing a VoIP platform that doesn‘t just meet the organization‘s voice needs, but adds value to its technology stack as a whole. Forward-thinking CIOs will architect their communications strategy around VoIP as a source of integration and leverage its position as the intersection of software, data and network to drive business transformation.

The Future of VoIP is Bright

VoIP has already had a profound impact on business communications, but its true potential is just starting to be realized. As the trends outlined above take hold over the next few years, VoIP will become an even more strategic part of the enterprise technology landscape.

AI-powered capabilities will make VoIP systems smarter and more efficient. Tighter integration with business applications will turn voice data into a wellspring of customer intelligence. Enhanced security will enable companies to protect sensitive interactions and comply with emerging privacy regulations. And a vibrant API ecosystem will extend VoIP into every facet of the organization.

But beyond all the flashy technology, the next evolution of VoIP will ultimately be about one thing: enabling more meaningful human connections. In an increasingly digital world, voice is often the most powerful and personal way to engage with customers and colleagues. VoIP will be the conduit for the tens of billions of rich conversations that will continue to be at the heart of business relationships.

The writing is on the wall: voice is no longer optional, it‘s essential. And cloud-based VoIP will be the primary means of enabling it. If your organization hasn‘t yet put VoIP at the center of its communications strategy, 2024 will be the year to make the shift. Your customers and employees will thank you.
