Grandstream GSC3506 V2 30W SIP Multicast Paging Speaker for Schools, Offices & Facilities

Announcements over a clunky old PA system are a headache. Fuzzy audio, no call filtering, and anyone who can reach the intercom box gets through. The GSC3506 V2 fixes that. A 30-watt HD speaker with a proper acoustic chamber pushes clear audio across a hall or open-plan office. SIP paging, multicast paging, group paging and PTT all run over your existing network. Built-in whitelists, blacklists and greylists stop the phone from becoming an open door for scammers. Full-band and wide-band codecs including Opus and G.722 keep voices crisp. PoE means one cable to the ceiling or wall. Plug it in, point it at the room, done
