DSP9000 IP SIP PA Intercom System

1. Solution Description

Generally, a large factory is divided into several production departments, warehousing departments, office departments, front desks, restaurants, staff rest squares and other areas. The communication and coordination between traditional factory departments still rely on telephone for one-to-one communication, while modern large-scale factories use the Internet communication platform to build an internal voice communication system for information release, intercommunication, sharing and production scheduling, coordination, and notification release among various departments.
