similar to: DAHDI TDM440E still has echo on bridged connections

" Hello, I have been trying to get my Grandstream GXP2000 phones to stop showing ringing state on monitored extensions. But no matter where I put notifyringing=no asterisk still sends the ringing state to the phones. Is this a bug I should report or is there another way around it. Here is how i have my subscriptions setup: extensions.conf [demo] exten => 6100,hint,SIP/100 exten =>

Hi Steve; Currently with Dahdi, for the below configuration that we were using it in the rc.local, how it will be? I think there should be something new to be used instead of ztcfg, what it is? And what about other lines? They need to be changed? touch /var/lock/subsys/local /sbin/modprobe wctdm /sbin/ztcfg -vv /usr/sbin/fxotune -s /usr/sbin/safe_asterisk Regards Bilal --- On Thu, 5/1/08,

This may be commonly known but I haven't come across it so here goes, maybe it'll help someone: I have terrible echo with asterisk 1.2, zaptel 1.2.12, and a TDM400P with 1 FXS and two FXO modules. The Mark2 echo canceller with Aggressive turned on was the only setting that would make it acceptable. I found fxotune with this zaptel version to be broken. I pulled the latest fxotune.c

I noticed the following came into cvs head yesterday: > Update of /usr/cvsroot/zaptel > In directory mongoose.digium.com:/tmp/cvs-serv2118 > > Modified Files: > fxotune.c wctdm.c wctdm.h > Log Message: > More TDM card echo API modifications.

Hey all, First of all, some background: Fxotune is a utility that is used to tune the hybrid on FXO modules For all of you with FXO modules out there, fxotune can help you adjust the analog and digital hybrid that is on the FXO interface and tune it so that it maximizes echo return loss. This means that it will reduce your default echo which is received, and will help any echo cancellers

Not sure how to go about troubleshooting this, did a fresh install of CentOS 5.4x86 with a netinstall iso off the base and update repo followed by a install of dahdi-lniux/tools from the digium/asterisk repo, ran genconf on my single fxo tdm410p and rebooted, ran fxotune, rebooted and now this panic every time it restarts... Any known issues with the version of Dahdi in the repo's? Server is

I'm trying to learn to use fxotune and am getting the error: Could not fill input buffer - got -1 bytes, expected 4000 bytes Failure! when I run it. This is a new install of Asterisk 1.4 and zaptel 1.4. Also I can't really find an up to date how to on it. Am I supposed to place fxotune on my startup path and run fxotune -s once it is working correctly. Any nuggets of info are most

Hi, everyone: I am developing a system using Asterisk, TDM-400 analog cards, analog lines, and Polycom SIP phones for internal extensions. Initially there was bad echo but after a series of efforts, I've managed to reduce it to a negligible level (it only happens when both parties speak simultaneously, and even there, only for a few hundred milliseconds). From an echo standpoint, things are

Hi, Well, I have a big problem with Asterisk, my problem is that when I'm in a conversation, using zap channels, in a moment the line has a interferce that produce a sound in the conversation, this sound is a electratical sound I think, I was reading about that and I found that the utility fxotune can help me to change some settings about the audio and the supression of interferences.

I figured I'd answer my own thread and document what it took to get rid of the echo at my location. For those of you trying to get rid of echo, let me tell you, "what worked for that guy, probably won't work for you". I think we've all heard that before, and it's true. Let me assure you that echo can be removed from your phone lines. At 20 hours into my 40
