similar to: Octasic echo cancellation

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

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

This is a reminder that the Twin Cities Asterisk Users Group will be meeting this Saturday @ 11:30am. August 11 2007 TCAUG Meeting - Echo Cancellation Threat or Menace? Sound Choice Communications LLC Offices, Bloomington Start: 08/11/2007 - 11:30am Hey all you Twin cities Asterisk Users, It's time once again to have another meeting. The Main topic for the August 11th meeting is: Echo

Hi i need to install a server with this hardware: 1 OpenVox B800P 1 OpenVox A800P01 4 OpenVox FXS-100 FXS100 4 OctWare SoftEcho SOFTECHO Do you suggest 1.2 or 1.4 branch? Is now 1.4 stable ? I've tried 1.4 the last year but i've experienced many problems with misdn drivers. Thanks -- /*************/ nik600 https://sourceforge.net/projects/ccmanager

Generate a simple bindtests test for the PHP binding, so it is possible to easily test all the argument types. Unlike the bindtests for other languages, optional arguments are not tested, due to the limitations of optional arguments in PHP (or maybe they way we implement them). --- .gitignore | 1 + generator/bindtests.ml | 63 ++++++++++++++++++++++++++++++++++++++++++++++++++

Hi all, It's the first LLVM backend we do for our asynchronous DSP. So, I apologize if this is a trivial question! The target-independent DAG combiner performs the following transformation: sub n, c -> add n, -c For our target, negative constants are more costly to encode. What is the best place to revert to a sub instruction? Kind regards, -- Martin

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!

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

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

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

A better way to handle this is to a td pattern to match "add n, -c" to a subtraction. I believe several targets do something similar to this.

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

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

On my (out-of-tree) target I have 16 128-bit registers. Unaligned load/store are illegal. (must 16-bytes aligned) 8 of those registers are defined as callee-saved and 8 caller-saved. The default stack size is 4 bytes. The target implements dynamic stack realign to make sure the stack will always be aligned correctly when necessary. Yet I am still getting unaligned load/store when running this

Hi Jean-Marc, Thanks for the suggesting. I tried the test wtih my recording file offline through the testecho. I got the same result(no prepocessor echo suppression) as my recording file for that live call. Basically I don't see the difference between input_frame and output_frame. As I mentioned in my original post, the echo return loss is about 20db. I guess the echo cancelleris not really

All, Wonder why all my posts has no line breaker when it displayed the forum... I used Hotmail(Windows Live Mail) with FireFox 2.0. I am posting this msg with IE 7.0 and see if it make any difference. Anybody experienced the same issue and how to workaround it? Thanks a lot!
