WhatsApp’s entry into enterprise voice calling is reportedly poised to significantly disrupt traditional interactive voice response (IVR)-based telephony systems used by businesses. These legacy systems, which routed users through automated menus before connecting them to human agents, are now being challenged by a more interactive, artificial intelligence (AI)-enhanced alternative.
Enterprises such as Thomas Cook, Redcliffe Labs, HCG Hospitals, and Sobha Realty have already adopted WhatsApp Calling, with general availability set to begin on July 15, 2025. The shift signals a potential transformation of India’s call centre ecosystem, as AI-enabled WhatsApp interactions offer greater context, flexibility, and efficiency.
The timing is critical for telecom companies, which have already experienced revenue losses from SMS services due to over-the-top (OTT) messaging platforms. Now, with enterprise voice services, accounting for over 20 per cent of overall telecom revenue, also under threat, the financial impact could deepen.
Businesses say WhatsApp voice support enhances customer experience through personalised, media-rich conversations and faster resolutions, all at lower operational costs. As this mode of communication gains traction, telcos may need to rapidly rethink their enterprise strategies.
