...that the speex aec isn't doing a lot. As I read in the mailing list, some people are being successful using it, so I have some questions: 1) What does the ref and echo mean in your function call? "Echo" for me would be the nearend (microfone + echo) and "Ref" should be the farend (nearend speaker). But if I use them like that, nothing happens! 2) What's the filter length I should be using anyway? 3) I guess the output parameter is the mic ("echo" signal) without the "ref" (farend speaker) influence, right? 4) Does the Y output have some use? Any...

It doesn't mater if the call is incoming or outgoing. Call quality is fine. All cal...

When updating the speex sources from svn tree, I found that the following revision has corrupted the deallocation (segmentation fault): ------------------------------------------------------------------------ r9320 | jm | 2005-05-27 15:05:05 -0300 (Fri, 27 May 2005) | 2 lines Proper de-allocation When compiling with the 9316, everything works fine. but when I update with later

...but now I am seeing intermittent failures where no echo is cancelled. The AEC works about 75% of the time and seems robust. On an AEC failure I can hang up and call again which will initialize a new echo state and it usually works after that. I have also written a test app that takes a nearend and farend wav and various parameters like frame_size, filter_size and echo delay and this works flawlessly with the delay that I measured with our system. Is there anything I can do to resolve the other 25% of the time. I have tried lowering the mic input volumes. I see that there is an API to reset the ech...

So, I keep seeing references in the codebase to "video conference" uses for Asterisk. However, I am unaware of what end devices are currently supported by Asterisk. Searching through the archives for the term "video", I see a few other people have asked the same question, with no real reply. Nobody, it seems, has actually tested any video phones on Asterisk other than
