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

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 all, After reading great things about the OSLEC Echo Canceller (http://www.rowetel.com/ucasterisk/oslec) and seeing the reactions of people who have tried it on a recent Trixbox thread (http://www.trixbox.org/forums/trixbox-forums/open-discussion/need-people-echo-problems), it sounds like it is the "bees knees" for sorting out echo problems with cards like the x100p. Has anyone

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

Trying to build oslec. Following dahdi-linux README I copy drivers/staging/echo to dahdi-linux/drivers/staging. I uncomment the 2 oslec lines in drivers/dahdi/Kbuild. That doesn't work: /home/asterisk/build/dahdi/svn/dahdi-linux/drivers/dahdi/dahdi_echocan_oslec.c:33:35: error: ../staging/echo/oslec.h: No such file or directory So: wget

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, 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?

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:

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'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

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

I am about to setup a new machine and based on a thread in the freetel-oslec list, I came across the idea of compiling Intel optimizations in when using oslec w/ dahdi. So I edit dahdi-linux-complete-2.1.0.4+2.1.0.2/linux/drivers/dahdi/dahdi_config.h to #define CONFIG_DAHDI_MMX which on its own wont compile. It was suggested to edit dahdi-linux-complete-2.1.0.4+2.1.0.2/linux/drivers/dahdi/Kbuild

Hi, I was install OSLEC yesterday and my problems with echo are all solved. But now all my calls have a big noise at background. I was try change some filters in oslec-ctrl-panel.sh, but it don't save nothing who I do. Does anyone had the same problem? -------------- next part -------------- An HTML attachment was scrubbed...

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

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

Hi all, We need to get better echo cancellation on an Asterisk gateway. Currently it has two TE410P (1st gen) cards. So would it be possible to just buy two VPM450M cards ? Or do we need to buy two new TE412P cards ? In that case a Sangoma A108d card would be nice as well ? What configuration gives the best audio quality ?
