This study developed the Push-to-Talk over Internet (PTToI): Extended Streamlined Communication System for the Regional Communications and Electronics Unit 12 (RCEU12) of the Philippine National Police. The system addresses chronic communication delays caused by traditional radio equipment by integrating modern web technologies to provide fast, secure, and scalable real-time communication. Using React.js, Node.js, WebRTC, SignalR, Firebase Authentication, and OAuth 2.0, the PTToI platform enables low-latency voice transmission and efficient channel management across mobile and web environments. The system was deployed on Microsoft Azure and designed to support simultaneous users with stable performance. A descriptive-quantitative evaluation with 20 RCEU12 personnel assessed usability, functionality, accessibility, satisfaction, and acceptance. The PTToI system achieved an overall mean score of 4.73 (Excellent), reflecting strong user confidence, ease of use, and operational relevance. Despite challenges related to internet variability and limited testing time, the system demonstrated its capacity to enhance coordination, operational efficiency, and real-time communication among law enforcement personnel. The study highlights the potential of Internet-based PTT systems to modernize public safety communication and proposes future enhancements that may extend applicability to broader emergency response environments.
