similar to: Odd results from fxotune?

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

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.

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

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

My SM56 (Motorola X100P clone) has echo as hight as 38%, according to fxotune -d. But when trying to take action, it fxotune simply says it can't. ./fxotune -i3 -vvvv Running with parameters: doset=0 docalibrate=1 dodump=0 startdev=1 stopdev=252 calibtype=2 waveformtype=-1 delaytosilence=0 silencegoodfor=18

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. My

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

What does fxotune need to do its job correctly - complete silence on the line, or just absence of the dial tone? For how long? I've been trying to get a silent termination number out of my telco all morning and have come up empty. When I just dial "1" as some online guides suggest to break the dial tone, it is silent for a few seconds, then plays a "Your call cannot be

Hi All; I got to know (reading on the wiki) that fxotune was have a bug, and it has been fixed. But I do not know if my current asterisk version contain the fixed one or not? How can I know? My current asterisk version is 1.4.22 Any advise? Regards Bilal

Is it still needed to run fxotune on the TDM24XXE cards with hardware echo cancellation? Jerry

Hey all, guess I didn't include enough info in my last query. I'm having massive echo problems on our sip<=>fxo connections & have been reading up on echo cancellation & such. When I try to run fxotune I get the following error: Could not fill input buffer Tuning module 25.Failure! The system has two of the digium 4port fxo cards & one T1 card (which isn't fully

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,

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
