Thank you. It is clear now, so it was user error and I should read more documentation :) Unfortunately drag and drop isn't working. Is there any prerequisite? My host is FC20 and guest is Win2k8 server Thank you Vlad On Thu 20 Mar 2014 05:42:40 PM CET, Jonathon Jongsma wrote: > ----- Original Message ----- >> From: "Laszlo Pal (private)" <vlad@vlad.hu> >>

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

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

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

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, 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

I recently ran fxotune against our incoming PSTN lines to try and help with some echo problems. It produced the following fxotune.conf file: 2=8,253,2,244,255,10,244,3,253 3=4,0,0,0,0,0,0,0,0 4=4,0,0,0,0,0,0,0,0 I'm a bit surprised by all of the '0's for channels 3&4, esp. given that it's populated values for channel 2. Is this considered 'normal' behaviour, or

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

Thank you. The clipboard sharing working now. Do you have any idea for the mount issue? I suppose there is a way to share a specific directory between the guest and host like I did with vbox for example What exact modules needed for this function? The error message I've got this: mount -t 9p -o trans=virtio,version=9p2000.L hostshare /tmp/hostfiles mount: special device hostshare does not

Hello, Again one more question about hardware. What could you suggest me to buy. I need hardware to connect let's say 4 analog lines. (FXO). This hardware should "talk" to Asterisk of course.. Thanks very much for some advices :) Bartek -------------- next part -------------- An HTML attachment was scrubbed... URL:

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

I know this subjeact has been beaten in here so much, but, here is my issue.<br /><br />I have a TDM400 with 2 ports tied into our telco lines. I have run fxotune on the lines, and have got the conf file in my /etc folder. I have fxotune loading in my startup right after the drivers load up, then asterisk loads up. <br /><br />Problem! When calling out, we get a horible

Thank you for the suggestions Andrew. I have not come across some of them before and will give them a shot. Based on my reading, changing the motherboard should have minimal impact unless that motherboard and the TDM400P don't get along (aka. IRQ sharing). I have disabled everything that is not needed and I do not believe I have any IRQ problems and I am NEVER wrong ;). Calls are crisp and

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,
