This flush-mounted version of our SIP-enabled IP Indoor Intercom is an ideal interior door entry and two-way communication device. Perfect within diverse environments such as office settings, assisted living facilities, schools and universities, and so much more, the Flush Mounted SIP-enabled IP Intercom can be installed as part of your overall mass notification system. The device features the new cut-in box design, making flush mounting even easier than before. The device receives SIP and Multicast and provides a host of features, all network programmable, including microphone sensitivity and volume adjustable and works well for any private or public sector entity requiring mass notification and secure access.The SIP-enabled IP Indoor Flush Mount Intercom can be configured as a Night Ringer with two SIP extensions. One extension can be assigned to a page group for auto answer paging. The second extension can be assigned to a "First-to-Answer" Night Ring group with IP phones. An audio ring file is activated when the second SIP extension of the Intercom is dialed. If any of the IP phones in the ring group is answered (or if the caller hangs up), the Intercom stops ringing.
