When using the softphone, I get an echo when using computer or laptop speakers. This does not happen when using headphones or a telephone handset with Zippy. I know and understand why the echo is being caused (by the feedback), but my question is this...
Why does this type of echo only happen on the Phone Power softphone? I can talk voice on Yahoo Messenger, Windows Live Messenger, and Skype using computer or laptop speakers and there is never an echo.
The echo cancellation check box in the softphone does not remove the echo either. 95% of the time I do use headphones, so this is not a major issue. I am curious as to why this happens exclusively on the softphone and not with other VOIP programs.
