Done, no change - Hold your hand over the mouthpiece. If the echo subsides then turn down the volume of the phone. *You should actually keep the volume turned fairly low regardless, as VoIP connections are extra sensitive and you will experience better quality by doing so.
In the process of doing this - Move the IAD away from other electrical devices.
None there to remove - Remove any splitters or separate caller ID devices between the IAD and the phone. In many cases this can cause echo that you hear on your end.
Done, no change - Try using another phone cord, as some phone cables can be of poor quality.
Corded or Cordless the same - If you are using a cordless phone try to replace it with a corded phone (connected directly to the IAD and see if the echo stops.
Is it right to assume that there isn't a way to tweak this in expert mode of OBI202? - And: Echo in telephony systems is caused by two main phenomena: the first is acoustic echo due to microphone pickup of audio. The second is electrical echo due to mismatched impedance.
I have not tried this at all. I'll assume I'll need a headset with mic for this test - Lastly, what is the echo and sound quality like when you make a call GV in your browser, thus completely bypassing your Obi and your analog phone?
Thanks for the help (everyone)....
