Hello everybody, when I upgraded from RC1 to RC2 I didn't had any audio between my ATA286 and H323 EP (my post from 13/08/04) I checked further and discover that problem is with ATA286 who is unable to call. I always get an 404 error. Coming back to RC1 everything works fine again. I tried to modify my dtmfmode from rfc2833 to info but in change nothing. Local call to asterisk are

Hi, I'm having an interesting problem with my card. It seems to work fine, for the most part. When I first load the module and asterisk, it detects the line in the on-hook state. However, after the first phone call, zap show channel 1 lists it as being off-hook. During subsequent calls, the card is listed as being on-hook, and when it's not used -- off-hook. There are also some weird

I've had a few problems with my system holding the line after a call has been made, just now I rebooted and noticed the following in /var/log/messages Aug 13 17:23:15 Sheriff kernel: wcfxo: DAA mode is 'FCC' in the file wcfxo.c the following structure is initialised as below which would suggest that FCC is wrong for France or pretty well all of Europe. static struct fxo_mode {

My TDM400P w/ 4 FXO cards seems to have trouble with onhook/offhook switching. It dials perfectly, but does not seem to be changing the onhook/offhook state appropriately. It changes sometimes, but it's not really reliable. For example: When I booted the machine, it started as onhook. It remained "onhook" through the entire first call (which was silent on both ends --

Hello, In my quest to figure out the source of the random echo on our shiny new asterisk install, I have been using ztmonitor on the TDM400p channels for the good part of today. I have 2 TDM400p cards with 8 FXO modules and 6 pots lines connected to them (last 2 channels are unused but configured in zaptel). Even when the lines are onhook, the Tx values settle down to 0 but the Rx values still

Hi, I'm not sure if I just missed something somewhere along the way, but I noticed while I was going through the CVS logs that there is an option in the wcfxs module to set an "opermode" - which apparently might help with echo issues around the globe (like the ones I'm seeing - some times). So I'd love to use it and give it a go. Apparently, there are some options that

Hi Can TDM400P detect polarity reversal on FXO module? We have C.O. lines that reverse polarity on Answer and release.

Hi! I want to get audio from the PSTN before the call is answered so I don't miss when the called phone is busy or if there is some error (like the phone is unavailable or is wrong, etc) and hear the ringing from my telco. I have polarity reversal in my telco for incoming and outgoing calls. If I set answeronpolarityswitch=yes then I get no audio until the call is answered. If I set it to

Hello, This is a little off-topic. I have an Ericsson FCT f251m, according to the specs it supports call signalling through polarity reversals and loop break, but it's currently disabled. On my PSTN line, my TelCo does send polarity switchs to signal answer and hangup (answeronpolarityswitch=yes and hanguponpolarityswitch=yes in zapata.conf), and asterisk detects it alright. I've been

Can anyone tell me what this message means? Got event 17 (Polarity Reversal)... I'm running DAHDI 2.0 with a TDM401 card. Asterisk version 1.6.0. It appears that I get this Polarity Reversal each time an inbound call hangs up. This results in another ring, but no one is there. It appears as an unknown caller, but I believe its a phantom. Thanks, Jim [Oct 10 12:47:54] NOTICE[6669]:

Hi, I am interesting how can I use the capabilities of ProSLIC to measure the following PSTN parameters: - Voltage (V) & Polarity (+-); - Current (A); - Frequency (Hz). Are there any ready for use tools? If there aren't ready for use tools how can I do the above measuring? Best Regards, Miroslav Nachev

Hi, I have been trying to build openssh 3.4p1 on SCO Open Server xxx It requires the libcrypto.a library produced by OpenSSL. So, I downloaded and installed OpenSSL 0.9.6d. As part of the configure process for OpenSSH, 'configure' checks for version of libcrypto.a with RAND_add(). RAND_add is defined in rand_lib.c and during the build of OpenSSH, I can see that rand_lib.c is compiled

Hi! The X100P is working - partly. I can make outgoing calls. But the card has got a problem detecting incoming calls. Even in verbose mode I don't see any hint that the card detects a call. At the moment I'm using the card behind my old ISDN telephone system. Could it be a problem with the line voltage? Can I adjust anything when loading the kernel module? Bye! Michael

I have an x100p which suffers from echo (no surprise there apparantly :), and a few of the things I've read about tuning out echo say the first thing to get right is the tx and rx gain, and for that you need a few different types of test lines from the telco (Telstra, Optus, whatever). Does anyone have any numbers in Australia for such lines? I think they just need to send out a tone of a

hi: In my zapata.conf i have 4 fxo configured channels,for fxo number 1 to 3 i added polarity reversal property but for fxo number 4 i didnt add polarity reversal property but it still giving me on cosole that fxo number 4 is polarized (because the line on fxo number 4 is not polarized). what i want to do is to not let polarity reversal take effect on fxo number 4. that what i have in my

Hi ! I ma having trouble with my PTSN line.

I would like to know if any body tried to connect gsm gateway with polarity reversal to fxo module at asterisk server ,and if the polarity reversal solve the problem of the answer and hangup supervison on calls .i appreciate any help.Thanks in advance;Wassim _________________________________________________________________ Express yourself instantly with MSN Messenger!

Hi people, I would like to read your suggestions as to where the issue might be. ATA286=Grandstream Budgetone ATA 286 in SIP mode. One Lan Port and one FXS port. TDM04B= 4 FXO signal fxls There is a 8FXO-to-SIP unit in this scenario that works perfectly so i will not make mention of it.
