Q. What can I do if I am experiencing buzzing sound when I speak through the handset?
Access the SPA922 web-based setup page.
Click Admin Login then advanced.
Scroll down and look for Audio Input Gain (dB). Set the Handset Input Gain to -6 or 6.?
Note: Check the sound quality on the phone to determine if it has improved. If this did not work, proceed to Step 6.
Click EXT 1.
Look for Silence Supp Enable and set it to yes.
Note: If you are still encountering the same problem after these changes, reset the device to factory default and reconfigure it.
