Hi all, We have just set up trixbox latest with a Rhino r1t1 card, hooked up to a plain E1 PRI line. We call fine SIP to SIP, but as soon as we make a call from SIP to PSTN all sounds become unintelligible screeching or static kind of noise on both ends, when we call PSTN to SIP the PSTN side seemingly OK at least we hear no screeching sound, but the SIP side is a even worse screeching sound. To be certain all is as plain as possible we disabled all echo canceling, and we use only alaw. Any ideas on wha...

...cond that the rxfax disappeared, I was able to call home. My wife said "it wasn't me, and there was a horrible fax sound on the line and I couldn't make any calls". Now, what is really interesting is the micro second before the call dropped, I heard my youngest child start to screech - dinner was being served, he was hungry ;) What I am surmising is that the fax detection is still running on a connected call, and decided that the child's screech was a fax machine and jumped into receiving a fax . Is this possible ? I do have fax detection on (zapata.conf). Is there an...

Hi, Is there any native software for OS X to convert an audio file to speex? Even a command line would be great. I looked for hours and couldn't find a program. I tried VLC but it just outputs screeching noises. Sincerely, Patrick Krol patrick9@net-link.net

I'm sure dumb when it comes to describing things that happen on my system. I'm making an outbound call on my ATA186 when another call comes in. I first get the nasty CID screech and then the periodic call-waiting tone. So far, so good. Then I hookflash, and just like it's supposed to, the waiting caller is on the line. But during the duration of that conversation, my console is going crazy, spewing this message: -z: No such file or directory -z: No such fil...

In the simplest terms I can think of, I'm going to describe what I want to do and I want to know if it's possible in the current version of asterisk. Can I take a T38 call from an ATA, convert that back to analog and have asterisk screech that out on a POTS line to a remote fax machine. Would it work? And could I receive an incoming fax the same way? Please don't talk to me about alternatives to faxing. I can't take the fax machine away from the end user, they don't want to hear about it. I either need to make it...

...plus it adds a little more delay that confuses the called party. Also, when I tried this I realized yet another issue, which could be the underlying cause of the whole thing. No matter what sound it is, no matter if I use AMD or not, the very first sound that I play results in a short "screech" sound before it is played. This happens every time without fail. If I were to guess, I would say that there is some data in the audio channel that is not audio data, and is being represented with that screech sound...but of course that's just a guess. Any help would be greatly appre...

I just deployed * on my home system last Sunday. 2x since then the Zap hardware seems to have malfunctioned on some way. One time it would just screech out one FXS, even though it would ring. The other time * would bridge to my FXO but it never got out on the line. I have a new TDM400 with 3 FXS and 1 FXO. Both times I tried unloading the zaptel drivers (which worked) and reloading them, which failed. A reboot of the system brought everything...

Hello all, First, the vital stats: FreeBSD 6.1-STABLE, dovecot 1.0.rc7 from ports. I have run into a vexing little problem that has brought my deployment of a shiny new dovecot server to a screeching halt. Using 'periodic' I've configured regular backups to occur using 'dump'. I have a monthly level 0, a weekly level 4, and a daily level 8. These dumps take advantage of snapshots to ensure they are taking a backup of a consistent filesystem. As part of the beta testing, I...

...p-info.org> without any success. Hope someone can point me to the right direction. I saw a couple similar questions, but don't see any answers. Fedora Core 2 2 X100P(clone) PSTN Asterisk 1.07 Everything seems to be running fine, but on occasion, Asterisk answers the call with high pitch screech sound (like fax or modem connect), it plays the normal greeting after a few seconds. I was getting this with either 1 or 2 X100P card installed. This seems to happen when a call ends and another one comes in. Just a side note, one thing after I installed the 2nd X100P card, the 2nd card won...

...ver I have no issues, however when I make a call using Originate : 'Channel'=>"SIP/1XXXXXXXXXX@sip.broadvoice.com", 'Context'=>'mycontext', 'Exten'=>'899', 'Priority'=>1, 'Callerid'=>'whatever')); It creates a screech sound when the first audio file is played. Doesn't seem to happen with another VSP I tried, but still, why would a regular outbound call work just fine and Originate create this strange sound. I know for sure that it isn't the audio file that I'm playing by the way.

...PSTN->asterisk->hylafax->pc At the moment asterisk and hylafax are on the same box. I went and installed t38modem, hylafax, openh323 and so on.... got chan_oh323 compiled and installed. I can now dial an extension - it gets routed to t38modem, it picks up but I hear no modem tones (screeching) just silence. when I dial it with a fax machine the fax machine just says 'no carrier'. Looking at the hylafax logs I see t38modem answer but then get 'no carrier'. If I make t38modem dial an extension all I hear is a beeep.......beeep......beeep of a fax machine. Also when...

...es and is ready to be optimized in a single unit, whole-program style, with optimizations for the install platform included without having to make my compiler deal with it. And if modules targeting a different platform find their way into my build process, I definitely want to bring the build to a screeching halt.

...thers me is the section concerning the oplock_break problems. It seems that everything churns along fine with no noticable speed decrease until these messages start cropping up in the log files. We have roaving profiles and desktops, and once these messages start appearing in the log files, things screech to a halt, and most (if not all) of the computers will "halt". As you can see the share that is causing the problem here is the virus share (F-SECURE anti-virus communication directory) I can reproduce this pretty much at will (just have to reinstall 2.0). Are there any ideas about how...

...re else there is still something telling lvm that my root drive is on VolGroup00. Where is it, and how do I convince it that VolGroup00/Volume00 (or whatever the defaults are) is now DriveC/Centos? I suspect it may be hiding in initrd (compressed). Wherever it is, it brings the boot process to a screeching halt with a kernel panic when it tries to pivot mount the root drive. Until I get this figured out, my Centos install is dead, and I am back on my old Mandrake install. Ted Miller

...couple of hours unsuccessfully attempting to get dial-tone on the new FXS part. I gave up, made sure the old FXS still rang and went to bed. I should have tested further. This afternoon, I got a call at work telling me that the dialing out doesn't work. I tried dialing in and get a horrible screeching that reminds me of the data stream of an active modem call, but more harsh. I can hear voice underneath the noise but the voice is unintelligible. I assumed that the changes I made to my Asterisk configs had caused problems so I did a CVS roll back to the configs I had before I started with the...

I've been trying to get a console channel working without success. The sound card, which is built into the motherboard, is a VIA Technologies, Inc. VT82C686 AC97 Audio Controller. Using the oss drivers (vi82cxxx_audio) in kernel 2.4.23 and chan_oss, I just get beeps and screeches. Using alsa drivers (snd-via82cxx) and chan_oss (using the alsa oss emulation), playing sound works, but anything recorded via the mic has a weird scratchy echo over it. If I use a program other than asterisk to record (such as rec or arecord), the recording sounds fine. It works even if I...

Here is what 'file' says: sf-george.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz I see the logs on my web server as it tries to access it, but all I get is a screech out of the phone.
