Hi, I'm currently testing SoftEcho, an echo cancellation software for Asterisk from Octasic. I noticed an important increase of the quality of my coms, but I still have a few echo problems. There is an ERL parameter which corresponds to an initial ERL value probably to optimize the echo training or something in that kind. Is there a way to monitor, using one of the zttools, the instan...

We're looking at using 4 or 8 port T1 cards with echo cancellation and are evaluating brands to go with. We know that Sangoma has excellent solutions especially when it comes to echo. But we still have to hear about actual performance of a Digium card using the same Octasic DSP echo canceller. Would appreciate hearing something on this. --------------------------------- Sponsored Link Mortgage rates near 39yr lows. $420,000 Mortgage for $1,399/mo - Calculate new house payment -------------- next part -------------- An HTML attachment was scrubbed...

New never used bought by mistake ( 5V pci slot ) and stored... pls make offer, thanks and regards, Jean-louis Curty The TE207P is a bundling of our leading TE205P product and our new VPMOCT064 Octasic DSP-based echo cancellation module. The TE207P is Digium's and the industry's first two-port digital card featuring hardware-based echo cancellation. The new module enables users to eliminate echo tails up to 128ms or 1024 taps across all 64 channels in E1 mode or 48 channels in T1/J1 modes...

Hi, I just read a pressrelease from VON that Digium will soon be releaseing a couple of new cards. What got me interested was: "The TE420P and TE415P support 128ms of G.168 (2002)-compliant echo cancellation across their entire 128 channels." Does anyone know when thease will be released and what they will cost when released? Thanks!

Hi, I'm trying to get a TE212 working on a Dell PowerEdge 1850 running Debian etch using the latest release of libpri (1.4.0), zaptel (1.4.2.1) and asterisk (1.4.4). The initilization of the Octasic echo canceller seems to fail when the wct4xxp module is loaded. [...] VPM450: echo cancellation for 64 channels Failed to open chip, code 00103017! VPM450: Failed to initialize [...] By looking in the zaptel code, this error value (0x00103017) means cOCT6100_ERR_OPEN_EXTERNAL_MEM_BIST_FAILED. Is...

Hello LLVM, My target has a complex relaxation hierarchy. Perhaps a modest TableGen extension would help consolidate most of the work involved in choosing a relaxed opcode. I also notice the x86 relaxation code with a comment wondering if TableGen could improve life. Does the following outline sound interesting? 1) Add a new field of type 'Instruction' to the Instruction class called

Ok... I am reluctant to ask this question as I believe that it may be like asking what someones favorite linux distribution is... but I need to make an informed decision. We are getting ready to upgrade from a TE210P to a quad T1 card with echo cancellation. I am trying to decide between the Sangoma card and the Digium card. I need this to have great quality and I need it to work well. I would

I think it would make sense for (1) and (2). I am not sure if (3) is feasible in instcombine. (I am not too familiar with LoopInfo) For the Octasic's Opus platform, I modified shouldMergeGEPs in our fork to: if (GEP.hasAllZeroIndices() && !Src.hasAllZeroIndices() && !Src.hasOneUse()) return false; return Src.hasAllConstantIndices(); // was return false; Following that change, I noticed some performance gain...

Hi: I am working on a new system with a TDM-400P card with three FXO modules and one FXS module. The system has been in place for a week. Users are complaining of echo problems. I have noticed this echo myself. It varies in severity. It is sometimes bad enough to make it difficult to converse, but the users find it generally unacceptable. They miss their old phones, which just worked. As you can

...ackAlign is 4. Adding a check for stack realignable or putting all the 128-bit registers as caller-save will fix the problem. if (!TFI->isStackRealignable()) <--- new line Align = std::min(Align, StackAlign); Is this a bug or am I missing something?

Hi, To solve echo problems, I'm considering 2 alternatives. 1> Sangoma A104d - I can't find support for asterisk 1.2.1 2> Desktop echo canceller - http://www.oriontelecom.com/echo_canceller/desktop/e1_ec_desktop.html - I want to know where to buy and price. Any suggestion is appreciated. Thanks. Jason. p.s. : asterisk cli command "reload" can change rx_gain and

...b the release at: http://downloads.xiph.org/releases/speex/speex-1.2rc1.tar.gz As some of you may know, I've spent the past three years in Australia doing a post-doc at the CSIRO. It's now time for me to start doing real work, so I'm back to Canada and will start a new job next week at Octasic (http://www.octasic.com/). It shouldn't really change much for Speex, as I will continue to maintain it and work towards release 1.2. Cheers, Jean-Marc

...ities Asterisk Users, It's time once again to have another meeting. The Main topic for the August 11th meeting is: Echo Cancellation. Eric Osterberg will be hosting the meeting at Sound Choice Communications and answer all you questions about resolving or removing echo as well as a renew of Octasics SoftEcho product for asterisk. You can purchase license keys at the meeting for 10 dollars a channel for the SoftEcho product. We'll also show you how to improve your echo problems for free. Be sure to get here early as the chairs go fast. The August 11th meeting will be starting at 11:30...

Just noticed this today: Digium TE220B Dual Span T1/E1 PCI Express Card with Octasic DSP-based Echo Cancellation Module<http://www.voipsupply.com/product_info.php?products_id=3352> It's about time Digium got on the ball and made PCI-e cards.

...he first 5-15 ms and sometimes the last 2-10 ms of the DTMF tone. This shows up in recorded voicemail greetings -- you hear a very short DTMF '#', or sometimes two blips, at the end of the recording. I have a Mitel SX-200 connected to Asterisk 1.6.0.1 by a couple of Digium cards: a TE420 w/Octasic and pri_net signalling, and a TE220 w/o Octasic using em_wink signalling. Calls come in using either PRI or E&M depending on Mitel routing (you don't want to know...). Either way, the driver is doing software DTMF detection. (Looking through the DAHDI driver, hardware DTMF detection is alw...
