Global SIP Trunking Services Market to Reach USD 43.74 Billion by 2031: TMR Analysis


The Global SIP Trunking Services Market, valued at USD 11.96 billion in 2021, is poised for substantial growth, projected to reach USD 43.74 billion by 2031, advancing at a robust CAGR of 14.1% from 2022 to 2031. The increasing adoption of Voice over Internet Protocol (VoIP) services and the resultant decrease in telephony costs are primary drivers of this market expansion.

Key Market Drivers

The adoption of SIP trunking services is accelerating due to several factors:

  1. Cost Efficiency: SIP trunking significantly reduces the total cost of ownership by minimizing capital expenditures. By eliminating the need for PSTN gateway capacity across enterprises, businesses can achieve considerable cost savings.
  2. Demand for Long-Distance and International Calls: As the need for efficient and affordable long-distance communication grows, VoIP trunking services, which offer lower rates compared to traditional Time-division Multiplexing (TDM), are gaining traction.
  3. Shift to Cloud/Virtual PBX Systems: Businesses are increasingly adopting cloud/virtual PBX systems to reduce operational costs, and SIP trunk providers are responding by launching localized cloud communication solutions to expand their regional presence.

Market Insights

SIP trunking services utilize VoIP or PSTN to connect a Private Branch Exchange (PBX) to the Internet, facilitating communication with both fixed and mobile telephone subscribers. This technology enables businesses to transmit data and voice services over VoIP and PSTN lines, offering a modern, affordable, and versatile alternative to traditional landline connections. The rise in mobile technology usage and the adoption of Unified Communications-as-a-Service (UCaaS) platforms are further propelling the market.
