Hybrid Station Information
Posted by Matthew Kambic on 29 December 2015 12:52 AM

Hybrid Station Information

Hybrid Intercom Stations combine IoIP and SIP technology into one station. This is designated by the H revision at the end of the model number. For example the ET962A and SIP-ET962A became the ET962H. Going forward new projects will contain hybrid products when available.

Hybrid Intercom Stations can only be in one mode at a time. So you must pick if it will function as SIP or IoIP by choosing the Bootmode. All hybrid intercoms are in SIP mode by default. To switch the mode you must use the IPStationConfig software that comes with CCT800. This requires automatic discovery by layer 2 networking.

Technology Comparison:

Intercom Server or VoIP Server Required (like CUCM) Intercom Server required
Initial IP configuration by IPStationConfig. All other SIP configuration by web interface All configuration by IPStationConfig and CCT800
Up to 7kHz Audio Quality Up to 16kHz Audio Quality
Dynamic background noise suppression virtually eliminates all ambient noise N/A
Loudspeaker/microphone surveillance – ensures the availability of the Intercom station while reducing the need for manual verification of its functionality
N/A Audio monitoring – fully automated emergency calls triggered by defined noise levels for more security
Peer2Peer Audio – reduces network and server load to ensure efficient use of resources
N/A Audio recording and lip synchronous audio/video recording of conversations for documentation and evidence keeping purposes
Audio recording and lip synchronous audio/video recording of conversations for documentation and evidence keeping purposes
N/A Speech activity detection senses when calls are finished
(no microphone signal) and terminates the connection automatically
N/A Simplex mode for applications requiring controlled communication e.g. for security solutions based on the “push-to-talk/release-to-listen” method
OpenDuplex® for natural, hands-free communication
N/A IVC (Intelligent Volume Control) automatically adjusts the
device’s volume setting to the ambient noise level
N/A Public address functions
Output control by DTMF or URL Output control by any connected Intercom or Interface.
