New immersive communication formats

With 5G’s high bandwidth and speed, VoIP will pave the way for more immersive and lifelike communication formats, including holographic calls and photo-realistic video conferencing.

Blockchain to address VoIP security challenges

VoIP networks have faced security and privacy vulnerabilities due to issues like identity spoofing, eavesdropping etc. Blockchain technology is emerging as a solution to address these challenges.

Enhancing identity management

Blockchain identity management can authenticate users on a VoIP network in a highly secure, trusted manner. This prevents spoofing and similar identity attacks.

Securing call metadata

Blockchain’s distributed ledger structure can be used to securely store metadata of VoIP calls in an encrypted, decentralized form. This enhances privacy against surveillance risks.

Fraud prevention

Smart contracts can enable reliable verification of call payments in a VoIP network to prevent frauds like toll fraud and IRSF.

AI to revolutionize VoIP experience

The application of AI/ML technologies in VoIP networks will take user experience to the next level by enabling more intelligent, intuitive and proactive communication capabilities.

Intelligent routing

AI algorithms can smartly route calls in real-time on network conditions, analysis of communication patterns, predictive demand sensing etc. This optimizes quality.

Natural language capabilities

AI assistants integrated natively into VoIP networks will enable natural voice user interactions. Users may be able to make calls, check voicemails etc. via voice commands.

Hyper-personalized service

Leveraging user data and activity analytics, VoIP providers can offer hyper-personalized services tailored to customized profiles of individual customers.

Proliferation of VoIP for global mobility

VoIP in tandem with 5G will enable the proliferation of cloud telephony services. Users will be able to seamlessly access enterprise phone systems globally on the move by just connecting to high-speed data networks.

Enabling work from anywhere

Businesses around the world had to rapidly adjust to remote work needs during COVID-19. Cloud telephony solutions enabled by 5G-powered VoIP can fulfill these emerging needs for flexible anytime/anywhere work.

Seamless international roaming

VoIP will allow globe-trotting enterprises to access their home country’s phone system in a low cost manner. Employees travelling abroad can seamlessly make/receive business calls through cloud telephony.

Powering omnichannel communication

With 5G enabled VoIP mobility, businesses can provide their customers access to unified communication channels including voice calls/voicemails across platforms like mobile apps, websites etc.

Transition from hardware PBX to cloud platforms

The growing reliability, security and capabilities of cloud voice platforms are prompting businesses to migrate from legacy phone systems.

On-demand scalability

VoIP platforms provide flexibility to scale up communications capabilities on-demand to match evolving business requirements in real-time. Large hardware upgrades are not needed.

Advanced unified communication apps integration

Cloud telephony interfaces like CPaaS allow easy integration with cutting edge apps for enabling video meetings, team chat services etc. under one interface.

Hassle-free management

Cloud telephony solutions significantly simplify the management overhead compared to maintaining large on premise hardware/software phone systems while also optimizing costs.

WebRTC ushering a new era

WebRTC (Web Real Time Communications) is paving the way for integrating real-time voice/video communication capabilities natively into web apps for delivering next-gen VoIP services.

Eliminating app download needs

Communication can now directly occur on browsers rather than needing standalone apps installation on devices.

Supporting interactive apps use cases

WebRTC makes it easy for apps across sectors like telehealth, interactive gaming etc. to enable video calling, file sharing and more natively.

Simplifying access across platforms/devices

Web app frameworks like JS, HTML5, WebAssembly support seamless delivery of WebRTC communication uniformly across smartphones, desktops etc.
