Session Initiation Protocol (SIP) Trunking Services Market: Growth Drivers

Rising launch of 5G telecommunications services to transform the industry’s growth rate

The global session initiation protocol (SIP) trunking services market is expected to grow due to the rising launch of 5G telecommunication infrastructure worldwide. 5G internet connectivity will allow SIP trunking service providers to deliver faster solutions that work at exceptionally high speeds and promote better-quality audio or video calls.

In addition, 5G internet connectivity will aid improvements in the development of more functional and highly advanced unified communication systems. It will open opportunities for end-users to integrate virtual reality (VR) and artificial reality (AR) in business meetings and communications. 5G technology is witnessing rapid expansion across the globe, with every major economy upscaling its investment in building a more robust and supportive 5G infrastructure.

For instance, in October 2024, the European Commission (EC) announced an investment of EUR 865 million toward the Connecting Europe Facility (CEF) Digital initiative.

With the renewed investments, the EC has escalated its support for more secure and faster digital connectivity networks. Some of the major areas of action of the EC will be deploying 5G infrastructures across the region, deployment of operational digital platforms for transport or energy infrastructures, and deployment and significant upgrade of backbone networks.

Cost efficiency offered by SIP trunking services to create market revenue in the long run

The demand for SIP trunking services is expected to be fueled by the cost-efficiency offered by the technology. For instance, traditional phone lines with international call features require extensive installation and maintenance costs.

Since the solutions available in the global session initiation protocol (SIP) trunking services are charged on a per-channel basis, the end-user pays only for the services used. SIP trunk pricing includes basic components that are actual call charges, price per channel that may include a call allowance, monthly rental charge for the broadband line, and a setup fee.
