The Growth of SIP Trunking in India
The way businesses handle voice communication is rapidly changing. Traditional PRI-based telephony is giving way to SIP trunking, a modern, internet-based way to manage enterprise calls.
According to Grand View Research, the global SIP trunking market surpassed USD 14 billion in 2023 and is expected to grow at a 12% CAGR through 2030, reaching nearly USD 25 billion.
In India, this shift is being accelerated by remote work, digital transformation, and cloud adoption. Companies are adopting SIP trunks to:
-
Cut communication costs by 40–60%
-
Enable remote and hybrid teams
-
Integrate telephony with CRMs like Zoho, Salesforce, and HubSpot
-
Improve uptime through carrier redundancy and cloud routing
