• Remote/hybrid teams—unified access anywhere.

Problems solved:

• Eliminates dependence on physical infrastructure.

• Reduces call-cost burdens.

Recent Updates – Trends and Changes in the Past Year

AI Integration

Artificial intelligence is increasingly embedded in VoIP systems—providing automatic call routing, sentiment analysis, live transcription, and voice intelligence tools for real-time feedback.

Internet & Network Improvements

Faster, more affordable broadband and expanding 5G networks are making VoIP calls clearer and more reliable.

Enhanced Security

Stronger encryption, blockchain-based logging, AI-powered threat detection, and secure protocols (like SRTP, ZRTP) are rising to protect VoIP communications.

Unified Communication Platforms (UCaaS)

VoIP is now often bundled with messaging, conferencing, and collaboration tools into single UCaaS platforms—for example, cloud phone systems like Dialpad, GoToConnect, Aircall, RingCentral, Ooma Office, and Grasshopper.

Telecommunications Act, 2023

Effective January 2024, this Act replaces the Indian Telegraph Act (1885) and provides a modern telecom regulatory framework. It brings OTT services, including VoIP, under regulated telecom services, allows spectrum management, supports 5G rollout, and empowers the government for national-security measures.

TRAI & VoIP Guidelines

• VoIP is permitted, but VoIP gateways within India that connect to PSTN/PLMN (landlines/mobiles) are prohibited. PC-to-PC or internet-based calls are fine, but termination to regular phone numbers is restricted unless using approved arrangements.

• Providers need proper licenses such as Basic Service License, Unified Access Service License (UASL), or CMTS.

KYC and Bulk Communications

As of June 2025, the Department of Telecommunications (DoT) mandates end-user KYC for all mobile numbers used in bulk business communications to increase accountability.

Do-Not-Disturb (DND) / UCC Regulations

TRAI enforces a National Customer Preference Register (NCPR), formerly DND registry, to let consumers opt out of unsolicited communications. Businesses must not call numbers registered in DND and must follow telemarketing permissions.

Data Protection (DPDPA, 2023)

India’s Digital Personal Data Protection Act, 2023 mandates that businesses handling personal data (e.g., call logs, numbers, recordings) comply with privacy obligations. Significant Data Fiduciaries may need to appoint DPOs and provide consumer rights for deletion or withdrawal of consent.

FAQs – Frequently Asked Questions

What is the difference between hosted (cloud) VoIP and on-premises VoIP?
Hosted (cloud) VoIP is managed by third-party vendors and accessed over the internet—low upfront cost, scalable, minimal equipment to maintain. On-premises systems (IP-PBX) are installed and maintained onsite—offering greater control but requiring higher investment.

Is VoIP legal in India for business?
Yes, but with restrictions. Internet-to-Internet (PC-to-PC) VoIP is allowed. VoIP gateways that connect to Indian PSTN/PLMN or create local phone numbers are prohibited unless licensed. Providers must hold appropriate telecom licenses.

Do businesses need to follow DND or data-protection rules for VoIP calls?
Yes. Businesses must avoid calling numbers registered on India’s DND list per TRAI rules. Under the Digital Personal Data Protection Act, handling of call data or recordings must meet privacy requirements.

What are the latest trends in VoIP for businesses?
Key trends include AI-enhanced features, improved internet speeds with 5G, stronger security protocols, and convergence into UCaaS platforms.

How can a business choose the right VoIP provider?
Consider business size, budget, required features (AI tools, CRM integration), compliance needs (security, licensing), scalability, mobile access, and ease of setup.
