I get an echo when going from a SIP phone to a PRI trunk. I hear the echo on the SIP phone. From reading some other post I think that I need to tell me phone company to turn on echo canceling. If the echo was on the other end than it would be my problem? Is this right? What exactly should I say to my phone company so they know exactly what I'm talking about? -- Michael Sampson Information Systems Manager Customer Contact Services msampson@yourccsteam.com 952-936-4000

...;m a hardware person who has recently found himself thrust into a software role. So, please forgive any ignorance in the following questions. I've tried to do my homework reading the relevant manual pages and investigating the Doxygen documentation. :-) We're investigating acoustic echo cancellation solutions for a speech application. Our hardware will be a TI C64x+ series processor (DM6467) which has both a DSP and ARM9 core. Our audio will be sampled at 8kHz and fed in through the I2S ports on the DM6467, echo cancelled, and then encoded in G.711. As such, I'm really interested in...

I'm using bristuffed Asterisk with ISDN/ZAPHFC I have VERY ugly (outgoing) sound through ISDN/HFC if echocancel=yes in zapata.conf, but without echocancel I have bad (incoming) echo Through PSTN/FXO sound is ok with or without echocancel.

Hi, I've had some decent luck with the mark3 echo canceller from the zaptel driver, echos on about 20% of the calls, people I've called say I sound great now, but our side hears echos. I was wondering if there was any way to tweak the current software cancelers into using more CPU (and hopefully doing a better job, close to a hardware canceler), I on...

I apologise for what is probably a totally noob question here, but I''m at a loss after pouring over the docs and the source code for prototype and scriptaculous... After you''ve started an effect, how do you access it to cancel or change it? I had assumed it was something like this: myEffect = new Effect.Appear(element, {duration:1.5}); myEffect.cancel(); ... but that doesn''t work. Any tips or pointers on how to approach this? It would be hugely useful for a ex-Flash guy like me for each effect to have method...

? ? Hi Jean-Marc, When speech is played in speaker, we are feeding that speech to echo canceller for cancelling its echo from captured data and the echo canceller work very well. But when there is no speech, we are feeding samples of value zero to speaker and the same to echo canceller. But microphone is always capturing something. But when speech is played again after these zeros(silent pe...
