dude it's gotta be something with your system. Im using same setup at home with a TDM22 with no probs. Asterisk@Home 1.5, Compaq Deskpro EN P3 500, cordless phones. You did a ton more than I did, I basically plugged everything in and installed a@h.Worked first try. Hate to say it, but would it be possible to try a different system? Even an old system as long as it is PCI 2.2. The big clue

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

I am currently running Asterisk 1.2.8, on an AMD Sempron 3100+ (ASUS K8N Nforce based board). I am using a Digium wctdm24xxp to terminate 8 (2x quad) FXO lines. Using ztmonitor (From zapata) I cannot see that there is any registerable incoming volume from these lines. I've been running them at rxgain = 25 (zapata.conf) to make the audio audible, however this creates poor call quality issues

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, 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

Group Having trouble installing zaptel.

I have seen mention of limiting a single server to no more than 100 trunks. With Sangoma having an 9 T1 card that kind of blows that limit. How many T1's can we have on a single server assuming dual Xeons? Our application calls for 122 IP Phones and 120 analog ports for faxes. Its an executive suite and we need the fax ports. No way around that requirement. Thanks, Allen.

Chuck, Thank You I'm also going to try CentOS 3 The problem is I have SATA HDD and running in to trouble getting Linux installed.

FYI: I am trying to build zaptel-1.2.4 against the recently updated kernel version 2.6.9-34.EL on Centos 4.2. but I am getting errors and it will not build. This is apparently due to a typo in a kernel header spinlock.h although I have not successfully modified the kernel and built zaptel against it yet. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=180568 This bug report has a typo

Canuck15, No, I hadn't played with the gains. But I've now done so and no difference unfortunately. Thanks for the suggestion though. I have discovered that after Asterisk has answered the call and the remote caller has hung up, if I lift the receiver on a phone connected to the line (in parallel with Asterisk), Asterisk then DOES instantly hang up. Would it be reasonable to assume the

Hi, I'm still strugling with getting an easy to use conference system implemented. I did have app_conference running, but today I upgraded asterisk to 1.0.9 and it stopped working. I've tried following the instructions for compiling app_conference on 1.0.7 but it didn't work. So I went back to ztdummy (I've not had any luck getting this to compile on FC2). Anyhoo, I've

To start ztmonitor in quantitative mode you do the following. Assuming you are running Asterisk V1.0.9 you need to edit one line to ztmonitor.c in /usr/src/zaptel as per patch 2783 http://bugs.digium.com/bug_view_page.php?bug_id=0002783 Change line 261 fprintf(stderr, "Usage: ztmonitor <channel num> [-v] [-f FILE]\n"); to fprintf(stderr, "Usage: ztmonitor <channel

I'm a neewbie in Linux, so please bear with me. I have a school assignment to make communication between 10 SIP softphones (kphone). So far I got trouble installing Asterisk. The information in asterisk web site seems to be a bit outdated because it's mentioned only kernel 2.4. Since Mandrake cooker (10.2beta3) witch I'm using is using kernel 2.6.10, I wander if I have a chance to

Hello, I have a TDM400P with 4 FXO ports, currently using three. When sending or receiving calls on this card, there is a nearly constant popping/clicking sound, it is related to the echo cancellation?. I adjusted my gains properly, but to no avail. I even found that setting echotraining=no in zapata.conf didn't change the scenario at all. I've plugged analog handsets into the

I am trying to obtain optimum gain settings for a bank of analog lines connected to a channel bank. My telco has provided a 'Type 102' test line to use for incoming level calibration. This is functionally equivalent to app Milliwatt(), but provides tone from the CO inwards. Question is, how should one use this a 0dbm test source with ztmonitor? Am I correct in understanding that a 0dbm

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
