SIP Trunking Services Market Drivers:

• Growing adoption of unified communication in enterprises

In traditional telephone services, the service provider delivers a bundle of physical wires to a business, whereas SIP trunks allow companies to use Public Switched Telephone Network (PSTN) connectivity through an IP network such as the internet, due to which enterprises are adopting unified communication solutions which reduce their telephony costs and generate ROI facilitated by the SIP trunking service. The growing adoption of UC in enterprises is driving the growth of the global SIP trunking service market across various countries worldwide. For instance, Matrix launched SARVAM UCS – Unified Communication Server for Modern Enterprises, which is designed to eliminate barriers that have traditionally separated voice calls, email, instant messaging, and conferencing in all forms. UCaaS is changing the deployment and management of businesses and making it easy to adopt and scale UCC within an enterprise which makes it easier for enterprises to manage costs while scaling up and down new services. Tata Communications and West collaborated to combine a global leader in UCC with one of the world’s largest communications providers to give enterprises rapid access to UCC platforms and better connectivity.

• Increased demand for SIP Trunking Services from BFSI

One of the prime factors driving the growth of the SIP trunking services market is its growing demand from the BFSI sector. The companies operating in the BFSI sector are under continuous pressure to offer maximum network connectivity to customers and value chain partners by maintaining low operational costs and communication timing. SIP trunking services help the BFSI sector to simplify communication management as they offer customized inbound call routing for fast and efficient call processing, provides full integration with existing and new external paging systems, offers integration between smartphones and cell phones, interconnection of various branches, and seamless call transfers between locations. Due to the various benefits offered by the SIP trunking services, their demand is high across the BFSI sector, which is expected to impact the overall market growth positively.
