Echo in voice conference

[GoogleCodeExporter]

Hello,

Echo in voice conference is a big issue for me. I know I can solve the echo 
issue if I follow the instruction given in FAQ 
(http://code.google.com/p/bigbluebutton/wiki/FAQ#Why_is_there_an_echo_in_the_voi
ce_conference?).

However, in most of my situation, I had conferences with people in rooms. Each 
room has several or even over 10 persons but only one computer. And, our 
conference discussion was free discussion. It was not easy to use the "raise 
hand" function. I am think if you can work on this. I know that skype does not 
have this problem, even if you use a laptop and use the buit-in mic and 
speakers. 

Thank you very much.

Hi Nathan Zhao,

Because BigBlueButton uses Asterisk/FreeSWITCH, you can engage a SIP Trunking 
provider to provide a dial in direct (DID) phone number to the 
Asterisk/FreeSWITCH server.

When you dial in through the phone system, Asterisk/FreeSWITCH provide echo 
cancellation.

You can try this on our demo server (it has a dial-in number in the chat 
window).

As for adding echo cancellation in VoIP, this one is out of our hands. It's a 
business decision by adobe not to offer it in Flash.  Again, your best path is 
to setup DIDs to your Asterisk/FreeSWITCH server.
