Nemertes: The evolution of SIP trunking

SIP trunking, a method of delivering voice over IP (VoIP) services to enterprises, has seen widespread adoption due to its cost-effectiveness and deployment flexibility. Over 57% of organizations have deployed SIP trunking, with nearly half experiencing reduced spending on PSTN access. The technology is rapidly evolving into cloud-based communications-as-a-service (CaaS), offering features such as global reach, routing of emergency services calls, virtual phone numbers, and integration with UCaaS platforms. IT leaders should revisit their SIP trunking strategies to evaluate potential cost savings and new feature capabilities offered by CaaS providers.
