similar to: CPU spikes with wcfxs loaded

I'm debugging a TxFax problem whereby the fax transmission fails. I suspect interrupt latency--some interrupt routine is holding its interrupt too long. I have all unnecessary services switched off and X is not running when I perform these tests. Some transmission are successful while others fail at random points. I've noticed that after I boot Linux, load zaptel, wcfxo, and wcfxs,

Hi All, I have a problem (at least I think it's a problem) where the wcfxs module causes constant CPU usage spikes. The card being used is a Digium Wildcard TDM400P with 3 FXO modules and 1 FXS (TDM31B). Monitoring my otherwise idle asterisk box (with top) I see once every 3-5 seconds hi (hardware interrupt) spike to 30%-40% and then drop back to 0 again. This is the case wtih both asterisk

Hello, I'm running Fedora Core 3 with udev, and asterisk/zaptel/libpri from cvs. I have followed the README.udev instructions replacing insmod with modprobe and rmmod with modprobe -r and adding the 60-zaptel.rules file, yet no matter what I do I still get this error on boot(or when I run service zaptel restart): [root@pbx ~]# /etc/init.d/zaptel restart Unloading zaptel hardware drivers:

Hi, I'm running into issues receiving faxes which, from what I have read, may be caused by frame slips. While I can find many posts saying to investigate it, I can't find any that describe *how* to debug the problem. Tried searching this list as well to no avail. Any pointers would be greatly appreciated. FYI, I'm running wbel, AMP 1.04, spandsp 2pre4. Faxing to a pstn on a

I've seen other posts about this problem, but I haven't found a solution. I'm dumping eight call files into the "outgoing" directory at one time. Three of the calls are successful while the other five are lost. Here is the call file: Channel: Zap/g2/3036701917 MaxRetries: 1000 RetryTime: 60 WaitTime: 45 Application: TxFAX Data: <filename>.tiff|caller Note: All

I'm having an intermittent problem with fax transmissions, something I call the streaking mascara syndrome. TxFax will be part way through a transmission when something fails--on the fax printer, part of the page will have correctly printed, but the rest of the page is "streaked" to the bottom. I have several successful multi-page transmissions interspersed with streaked

Does anyone know of a 24 port ATA device that could be installed in a phone closet? Like a channel bank, but, instead of multiplexing onto a T-1 circuit, it would convert to SIP/RTP on a LAN connection. Thanks, -- Michael Welter Introspect Telephony Corp.

Hi, I got my TDM11B and am trying to get it to work on my PC. However, I'm having difficulty getting the wcfxs driver to load. I've Googled this problem, and while there are others who have ran into the same problem, none of the solutions work for me. I would very much appreciate it if you could suggest things I could try to resolve this problem. Details follow. The PC is somewhat

I went on a service call yesterday to find an asterisk system with a T100P card on a Qwest PRI and a TDM40B card connected to fax machines. The TDM40B LEDs were not lit, and the system did not respond to keyboard input. However, calls were being processed for the PRI and 7960 phones. I replaced the TDM40B card with a new one, and the system now seems to be ok. But I'm wondering, why

Is there a Linux tool that will splice several gsm sound clips together into one clip? In my agi script, I would like to use 'get_data' with one clip instead of multiple 'stream_file' so the user doesn't have to listen to the entire spiel before responding.

hi guys, i got a TDM400P FXS card an everything is fine except for this when i do modprobe wcfxs , the linux shows 2 TigerJet Network Inc Model 300 128k. i don't know why it is showing 2 of them. or is that what it is?

Hello. I have this problem. In my asterisk box, I was running debian woody with asterisk package from backports.org. Last friday I upgraded from debian to sarge and change from kernel 2.4.18-1-686 to kernel 2.6.8-1-686, rebuild zaptel kernel module and also upgrade to asterisk 1.0.2. But now asterisk won't start. Here is more info #asterisk -vvvvvvvv (last lines) [chan_zap.so] =>

Hello I am (attempting) to run the astlinux version of Asterisk on a VIA embedded platform. I have a TDM04B and pretty sure zaptel.conf and zapata.conf setup OK. They worked fine with same card in traditional PC anyway. I think need the module wcfxs for a Digium TDM04B card. Is this module not part of astlinux? Do I need to download it? Or is it in opt? I see wctdm - but think that is

I finally got my ASUSCOM (Cologne chip) ISDNLink card working here in the US. When a call arrives, I get "Unknown IE 42 (Unknown Information Element)" and "Unknown IE 21 (Unknown Information Element)". IE 21 (0x15) is defined as Q931_CALL_STATE_SUSPEND_REQUEST. IE 42 (0x2a) is not defined in the code and I couldn't google it. Is this something perculiar with ISDN in

I need to connect a bunch of analog telephone sets. Does anyone have any comments about this channel bank? Disconnect supervision? Echo? ADSI problems? The price is right @ $995 new and $695 refurbished. Thanks, -- Michael Welter Introspect Telephony Corp. Denver, Colorado +1 303 674 2575 mike@introspect.com www.introspect.com

Hi all, Does somebody know why no load modules to FXS? I used zaptel-1.0.7 version driver. [root@server1 zaptel-1.0.7]# modprobe wctdm ZT_CHANCONFIG failed on channel 3: Invalid argument (22) Did you forget that FXS interfaces are configured with FXO signalling and that FXO interfaces use FXS signalling? /lib/modules/2.4.21-27.EL/misc/wcfxs.o: post-install wcfxs failed

Occasionally my /etc/hosts file gets corrupted. The IP address and the host name switch positions with the host name to the left. What this happens, my 7940 phones won't register. Fixing /etc/hosts allows the phones to register. Do any of you Linux gurus know who is corrupting the hosts file? Thanks, -- Michael Welter Introspect Telephony Corp.

Hi All, I have the problem setting up TDM22B card. Steps what I have followed are: [1] compiled zaptel-1.0.9.2 & installed the same. [2] modprobe wcfxo /lib/modules/2.4.20-8/misc/wcfxo.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg

Hi all, I have just purchased the DevKit from Digium and received a X100P and a TDM400P (it has one FXS module). The problem is that I can't get the kernel module (wcfxs) to load and run. I have searched the archives and can't find anything about this. Do the messages below ring any bells with anyone ? There is no interrupt clash (see pci list below). I am running on a AMD 1.2G
