CyberData SIP Emergency Intercom – Indoor Two-Way Audio, Push-to-Talk, TLS 1.2 Secure

When someone hits the emergency button in a school corridor or a warehouse loading dock, you need audio that works first try. No echo, no static, no 'can you hear me now.' This indoor SIP intercom does full-duplex two-way audio with acoustic echo cancellation, and push-to-talk from either side. It pages via multicast straight from Poly phones or any standard multicast source. TLS 1.2 and SRTP keep the connection secure whether your PBX is on-prem or in the cloud. Indoor use only
