VIP-9890-EM Emergency Talkback Call Station
The VIP-9890-EM Vandal Resistant IP Handsfree Emergency Talkback Call Station provides one-way or two-way communication to multiple answer locations. Pressing the “Call” button on the call station initiates a call to any SIP telephone, SIP address, PC softphone, Valcom intercom station or to a Valcom IP gateway. When the called party answers, a handsfree talkback communication is enabled. When the called party terminates the call, the connection is terminated automatically. A remote activated relay is provided allowing the use of a strobe light, remote door unlock or camera activation.
