The R&S®VS5400 telephony server acts as an interface between the VCS environment and standard telephony systems. It enables communications between CWPs, IP phones and other interconnected SIP trunks. The server also provides media conference resources between CWPs, IP phones and legacy equipment connected via CERTIUM GATEWAYS. It is one of the main building blocks within the CERTIUM ecosystem's VCS subsystem, as it coordinates all IP calls and manages traffic within the given topology.
