Can any one tell the reason why remote sites hearing their own voice through 2nd Gen phone.
both the sites are using 2nd Gen phone?
For the call audio output are you using the speaker of the second generation phone or the display speakers? If the phone is physically too close to the display speakers sound will go out the speakers and right back into the microphones causing an echo. Another possibility is that the Icon was not able to perform a ping test on bootup to properly calibrate the echo cancellation and would need to be rebooted with the display on and volume turned up. If you are using the speaker of the phone for audio output a Lifesize support case would be recommended as that is not expected behavior.
Kevin is correct, it is likely the party causing the issue is using the Monitor for audio out. Speaker placement, room conditions, along with settings may resolve the issue. A couple of additional points that may be helpful:
1. The side hearing the echo is not the side causing it. Need to check the settings/configuration of the video conferencing system not hearing the echo.
2. It is likely that the side causing the issue is using the Monitor for audio out. You may need to make changes to settings on the monitor:
a. Enable Game Mode – If available on the TV.
b. No game mode on the TV, look for and disable the following types of items.
-Digital surround sound
-Simulated surround sound
-Motion Smoothing – may be called "TruMotion," "CineMotion," or "Smooth Motion Plus"
-Cinema or Film mode
- Digital noise reduction
- Motion enhancement
-Any other processing or enhancement tool on the monitor
c. Note, some monitors do not have the processing power to decode audio in real time and may always give an echo.
3. Try setting the Phone for sound out - I have not seen an instance of echo when the Lifesize Phone is used for both audio input (mic) and output (speaker)
