The 2N SIP Speaker is an IP paging device with many useful functions. It can be used at the workplace, in schools, offices and other public spaces. You can use it with a loudspeaker as a simple PA system or with a microphone as a two-way intercom. The link between IP technology and an SIP protocol enables announcements to be sent to all the devices in the system, to select individual zones or call a specific device. With an external microphone and button, an end station can call up to three pre-selected numbers. It is then possible to control one external switch from these workplaces with any function based on the needs of the given operation. – Standalone Box Bundle (includes Speaker and Mic).
