Valcom VIP-172L Sip Enabled VoIP Door Phone Vandal Resistant

The VIP-172L series of IP Handsfree Talkback intercom with longline extender and dial code operated relay are the perfect solution to implementing Door Phone or similar functions with modern IP telephone systems. In a door answer application, a visitor pressing the “Call” button on the doorplate initiates a call to any SIP telephone, Valcom intercom station or to a Valcom IP gateway. When the called party answers, handsfree talkback communication is enabled. The called party may dial a code to activate a relay in the IP DoorPhone to unlock the door. When the called party terminates the call, the session is terminated automatically. The called party may be anywhere, across the street or across the world.. When used in a Command application, any location will automatically call the Command location. The Command location can call any station directly. The Command location can call any groups or can do an all call page using a single optional Valcom multicast Gateway.
