Cisco IP Interoperability and Collaboration System (Cisco IPICS) is an intelligent platform that controls media and information, enabling intra- and inter-organizational communication, interoperability, and operational efficiencies. By taking advantage of IP standards and protocols, Cisco IPICS bridges communications from existing and proprietary radio networks to IP networks and devices such as the IPICS Dispatch Console (IDC), and supported models of the Cisco Unified IP Phone. The Cisco IPICS license determines the number of concurrent land mobile radio (LMR) ports, multicast ports, IDC users, IP phone users, dial users, and ops views that are available for your system. The total number of LMR and multicast ports, IDC, IP phone, dial users, and ops views cannot exceed the number that is specified in the license or licenses that you purchased. – User License for Spectralink DECT Server 2500, 150 users
