The possibility to integrate intercom functionalities into the OPTIMA interface has become a reliable and very popular feature of the KNX CONTROL products. Due to the usage of VoIP technology the OPTIMA interface assumes the functionality of a small phone central and permits to integrate external units, IP phones, PCs & MACs, mobile devices and – if necessary – also gateways to external phone lines. It is only required that the devices using the VoIP functions are compatible with the SIP standard.
Incoming calls from the door station are shown on the integrated client devices of DIVUS OPTIMA and can be handled through a pop-up window. If the door station offers also a video signal, it can be displayed together with the incoming call. The graphical interface lets you accepts or decline the call, switch between different camera signals and also execute additional functions, like the door opener or other actions in the KNX system.
An additional advantage of the INTERCOM module is the possibility to connect KNX actions and VoIP calls: so it is for example possible to start calls automatically, depending on certain events within the KNX system. Furthermore, virtual phone numbers can be created and associated with KNX functions; if the number is called by a device like an IP phone, the associated KNX functions will be automatically executed.
As if this functionality would not be enough, your KNX CONTROL device can also be connected to an external phone line (either SIP or analog through a corresponding gateway); now, intercom calls can also be directed to numbers of the conventional phone and mobile network.
