Network trunking in a contact center context refers to the technology used to provide a communication link between two points, typically between the contact center's telephony system and the public switched telephone network (PSTN) or between different parts of a distributed contact center. It involves aggregating multiple voice or data channels onto a single physical line or link to optimize the utilization of network resources, reduce costs, and improve scalability. This is particularly important for efficiently managing high volumes of inbound and outbound calls, ensuring reliable and high-quality communication.
