Digital transformation (DX) is a significant undertaking for enterprises, with global spending on DX-enabling technologies and services projected to reach $1.97 trillion by 2022. CIOs are under pressure to increase efficiency while adopting flexible solutions across their organizations. Companies are moving away from legacy communication systems due to reasons such as unlimited scalability, better budget optimization, seamless transition, feature parity with legacy systems, and hassle-free access to new features. VoIP phone systems offer these benefits by enabling cloud communications and subscribing to a communications-as-a-service (CaaS) model.
