Essential Trading Systems Corp. (ETC) upgrades Robert W. Baird’s analog “Hoot ‘n’ Holler” system to their new VoIP “Simple Hoot ‘n’ Holler” system. For years, Robert W. Baird had a single channel “Hoot ‘n’ Holler” system in place and as their business expanded to include IPC’s new Unigy Turret Systems, the branch office “Hoot ‘n’ Holler” system required multiple talk groups to be distributed out to the branch offices. ETC’s Simple Hoot ‘n’ Holler includes the VG-500 Unicast to Multicast gateways and the CS-64 Multicast Microphone stations.
