similar to: OSLEC and zaptel-1.4.5.1

I wonder if anyone has any ideas on this. I have recently migrated my server from a custom built Linux with Asterisk, Zaptel and Oslec running fine, to Ubuntu Server 8.10. I have Asterisk installed via synaptic at it works fine. I have built and installed the zaptel package by doing the following commands: sudo m-a -t build zaptel cd /usr/src sudo dpkg -i zaptel-modules-{version}.deb sudo

Hi All, I have followed below steps to enable echo cancellation. # cd /usr/src # wget http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.28.tar.bz2 # tar xjf linux-2.6.28.tar.bz2 # tar zxvf dahdi-linux-2.1.0.4.tar.gz # ln -s /usr/src/dahdi-linux-2.1.0.4 /usr/src/dahdi # mkdir /usr/src/dahdi/drivers/staging # cp -fR /usr/src/linux-2.6.28/drivers/staging/echo /usr/src/dahdi/drivers/staging # sed -i

hi you, I'm having problem with voice quality on my trixbox using TDM2400B.The trixbox is connected via 20 FXO ports on a TDM2400 with the hardware echo cancel module. Echo cancel almost works, but the users hear what they describe as a 'background crackle/buzz' coming back when they talk. anyone have the same problem? pls help me. thanks a lot. my trixbox and config

Yesterday I pulled in the latest svn of Dahdi and added the files from a recent kernel in the drivers/staging/echo structure and modified the Kbuild file so it would compile without error. I insmod'ed the module in, and modified my system.conf has echocanceller=oslec. cat /proc/dahdi/1 shows: Span 1: WCTDM/0 "Wildcard TDM410P Board 1" (MASTER) IRQ misses: 1 1

Hello list, Can someone outline the steps for selecting OSLEC canceller in 1.4.6? I know there was a bug fix for this but I can't figure out how to select it.

So, people have recommended building a system from scratch, start with a CentOS base and installing asterisk and all of the other utilities. I've only used Trixbox for my business system. I'm wondering what surprises I'd run into. Right now, I know I'd need the OS, Asterisk, something like FreePBX, I have a x100p card so I'd need Zaptel, does that come with asterisk?

Hello all, Since a while some of our SIP users complain about gaps (sometimes multiple seconds of silence) in the RX audio stream (direction pbx -> phones). Our configuration is an Asterisk with two Wildcard TE410P cards that are connected with E1 PRI's to an external server running callcenter software. The SIP users use Snom and Polycom phones. The gaps are not present in

Hello list, I'm facing a little issue with dahdi attempting to load the OSLEC echo canceller into my current kernel. After compiling dahdi 2.3.0.1 with OSLEC support, I get the following error when set 'oslec' as the echocanceller: DAHDI_ATTACH_ECHOCAN failed on channel 1: Invalid argument (22) - Similar errors are *NOT* present using other echo canncelers. - I tried adding the

Hi, I've a problem: I can't configure DAHDI with ech canceller OSLEC. I have Asterisk 1.4.24 and DAHDI 2.1.0.2. I compiled also OSLEC. But when in /etc/dahdi/systems.conf I insert value echocanceller=oslec,1-4, command dahdi_cfg -vvvvvvvvvvvv give me an error about oslec. Someone can help me?

I go to my Zaptel 1.4.0 folder and run ./configure; make linux26; make install and I don't see any errors. This is out of my modprobe.conf: install tor2 /sbin/modprobe --ignore-install tor2 && /sbin/ztcfg install torisa /sbin/modprobe --ignore-install torisa && /sbin/ztcfg install wcusb /sbin/modprobe --ignore-install wcusb && /sbin/ztcfg install wcfxo

Hi list, I install dahdi-linux successfully with the module of oslec for the echo, but when I specify it in the system.conf the echo canceller oslec it shows me errors: DAHDI_ATTACH_ECHOCAN failed on channel 4: Invalid argument (22) I see that the echo cancellers is supported: mg2, kb1, sec2, and sec because oslec is not supported?, but he has support to compile it with dahdi_linux! best

Hi, I'm used to add OSLEC source code into asterisk and use it as default echo canceller. Currently, I'm proceeding this way: download the kernel source code roughly matching the kernel version I'm targeting with command such as "wget http://kernel.org/pub/linux/kernel/v3.0/linux-3.2.46.tar.bz2" copy the echo subtree into dahdi change dahdi's Kbuild file (for dahdi

In order solve my incoming caller ID problem, I upgrade the dahdi to version 2.6.1 from version 2.4.x. After upgrade, I found the echo cancellation doesn't working (I'm using Digium AEX800B PCI Express card). I can hear my self talking on the phone. How to solve this? I think I need to recompile dahdi 2.6.1 with OSLEC support? how? [root at callcenter ~]# dahdi_cfg -vvv DAHDI Tools

Hi List, I am having some trouble with installing the latest version of ztdummy on a CentOS Kernel 2.6 system. I have installed a few Asterisk systems on Slackware Kernel 2.4.x without any issues, unfortunately there is no choice about this distro, or kernel as it has been preinstalled by someone else. And so I am in the dark with an unfamiliar distro and kernel. I am fairly sure the

Hi List. I've bought a new server for my home asterisk installation and I'm trying to install asterisk with dahdi drivers and OSLEC. To do that I've got the svn dahdi-linux trunk revision 5366 and the echo subproject from the 2.6.28-rc6 Linux kernel sources. As reported in the dadhi README file I've uncommented out the two OSLEC related lines at Kbuild file in the

Hi All, Which echo cancellation is good between OSLEC and MG2. Dahdi by default use MG2 echo cancellation on channel. If i want to use OSLEC then what should i need to do ? Do i need to recompile dahdi with OSLEC ? -S -------------- next part -------------- An HTML attachment was scrubbed... URL:

I was previously using an old computer running Asterisk 1.2 with zaptel. Once the CPU fried I switch to a new computer and I chose AsteriskNow 1.5 running in 64bits to simplify the installation process. I manage to find my way with configuring dahdi instead of zaptel and to switch all my previous config to the new computer. Now everything is fine except that even if I use the md2 echo

Hello all, I'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+

I'm hoping someone can help me here. I've purchased replacement systems for 3 aging 1.4.x installs. I'm hoping to setup Asterisk 11, dahdi 2.6.1 and Oslec. I'm also moving those installs from Mandriva 10.0 to Debian 6.06 (Squeeze). In my testing, the TE220P PCIe cards that I have, the timing was awful on both slots, so I compiled Kernel 3.6.9 from kernel.org. Timing jumped to
