Gives you probably world´s only SIP stations with Loudspeaker- and Microphone Monitoring
SIP 3.4 Release – With new/updated software, Commend´s SIP stations are getting even more intelligent.
We are constantly developing and enhancing our SIP stations with the addition of new, powerful functions. Once again, SIP stations by Commend lead the way with their combination of high speech quality and innovative functionality.
The bar has now been raised even further with the release of the latest version SIP 3.4. Important additonal features are Loudspeaker-Microphone Monitoring, If/Then conditions within action sequences and the possibility to integrate Commend SIP stations into secured networks.
Here is how it works.The SIP station emits an audio signal through the loudspeaker, which is immediately “heard” and analysed by the microphone. The audio test signal is almost inaudible to the User.
The integrated DSP (digital signal processor) then compares the signal received by the microphone with the original one sent to the loudspeaker. If either component is not functioning properly (e. g., if the microphone has been blocked by something like chewing gum, or if the loudspeaker is wet or damaged), the DSP will detect this and send a message to the control room, from where a maintenance technician can be arranged to check and repair the station.
So Commend SIP stations do not have to be tested manually, as they are continuously doing so themselves. Not only does this save considerable time and effort, it also ensures the ultimate system availability, as a failure does not have to wait until the next routine check or until someone complains about the Intercom Station not working. Microphone and Loudspeaker Monitoring for SIP is quite a unique and nice feature compared to other DTMF based systems on the market. Smooth, secure communication is ensured precisely when and where it´s needed. Watch the video on YouTube
