similar to: Dahdi_dummy is more accurate than core timer?

Hi I wonder if anyone has any sugestions I have had a TDM400 for a couple of years, and I have always had problems with noise on the line, so tonight I have been doing some research and have found that if I load the CPU dahdi_test has almost perfect results and no noise dahdi_test Opened pseudo dahdi interface, measuring accuracy... 99.997% 99.999% 99.998% 99.997% 99.999% 99.998% 99.998%

Hi. I have a Debian Leni system with asterisk-1.8. I was trying to get meetme to work and it depends on dahdi, so I compiled dahdi-trunk and dahdi-tools-trunk, however, when trying to insert dahdi_dummy, it complained about symbol crc_ccitt_table, although the module was actually there in the kernel tree. So, I took the Debian source, and I had the config and I did make Bzimage, make modules

Hi, I am running Fedora 7 VM. On an earlier configuration with zaptel and Asterisk 1.4.21 , meetme worked alright. I upgraded to Dahdi and Asterisk 1.4.26, and the result is choppy sound via Meeme, while a simple Musiconhold works OK with descent audio quality. So I am sure its a Dahdi_dummy problem. Running dahdi_test gave me very poor results. Opened pseudo dahdi interface, measuring

Hi list! We currently have a PRI gateway composed by a box with two Digium quad-span PRI cards (a TE420 and a ). One of the cards is filled with TELCO1, while the other has first two slots filled with TELCO2, and 3rd slot with TELCO3. I am currently having (timer ?) issues on TELCO3 (span 7) D-Chan (202 as determined by dahdi_genconf ) is constantly failing causing on-going calls to terminate.

I have a pretty large setup on one of my customers. Digium TE420B (with echo cancelling module), 3 Xorcom Astribanks with 32 FXS each and 1 Xorcom Astribank with 16 FXO. These FXO ports are NOT used for fax/data transmission, as they are connected to cell phones. Not really related to the issue, but there are also 250 SIP phones. The problem is that fax and dial-up connections are really

I'm playing around with an ALIX 2D2 board (http://www.pcengines.ch/alix2d2.htm). It's a fanless, x86 system using an AMD Geode processor with 256MB of RAM. Also available are two network interfaces, two USB ports and one serial port (no keyboard or VGA). I'm using the Voyage Linux distro, which basically is Debian Lenny optimized for this board. Asterisk 1.6.1.12 runs fine on the

Hello there: I think I have a silly kernel configuration problem. I'm running: * vanilla 2.6.27.10 kernel built from source * dahdi-2.1.0.4 built from source So far so good, dahdi module loads just fine: dahdi: Telephony Interface Registered on major 196 dahdi: Version: 2.1.0.4 when I try to: hal04 dahdi # modprobe dahdi_dummy FATAL: Error inserting dahdi_dummy

Hi, Does anybody have an idea as to why dahdi_test results drop to unacceptable levels after doing a wanrouter stop/start using a Sangoma card? See below that it drops from 99.99% to 98.55%: [root at bin]# dahdi_test Opened pseudo dahdi interface, measuring accuracy... 99.999512% 99.992874% --- Results after 2 passes --- Best: 100.000 -- Worst: 99.993 -- Average: 99.996193, Difference:

Hi! I have Asterisk 1.6.1 installed on OpenSuSE 11.0 running with choppy sound. One specialist on the forums asked me if I have DAHDI configured, he assumed that this could be cause of choppy sound problem. > dahdi_test Unable to open dahdi interface: No such file or directory Do I need to configure DAHDI even if I do not have any Zaptel devices? Is there any guide for configuring

Hi all I am using asterisk 11.24.1 on a centos 5 machine. kernel 2.6.18 flavor. (x86_64). I have about SIP 150 endpoints on it. when I send a message I'm getting garbled audio. I used to have a single PRI card in the box - but something happened and that connection no longer worked. I removed the card and also removed the system.conf and chan_dahdi entries. I am using ConfBridge in a PA

Hello, I have at my disposal, 2, TE410P cards. I have setup an asterisk box that will function ONLY to handle meetme conferences over SIP. No PRI lines to be plugged into the 410 card. MeetMe requires an external timing source. Right now, using the dummy driver. Is it possible to use the card solely for timing purposes? Any benefit to doing so? Or should I just sell the cards?

I am sure many of you have seen my post asking question that I cannot seem to resolve. While the responses i have been getting have been helpful i still cannot seem to get this working 100%. So I have waving the white flag here. I give up. I need someone to come to my office and help me get this working. If anyone is interested the office is in Lexington KY. If someone is interested we can

Usually I used real Digium cards in asterisk systems, so I'm running into this for the first time. dahdi_tool reports that dahdi_dummy is in state UNCONFIGURED. This isn't super surprising, as it seems like the configuration files for DAHDI are really intended only for configuring real physical cards. But that begs the question: Is there any legal DAHDI configuration for dahdi_dummy such

Is there a method or can there be a method added to dahdi to only compile for dadhi_dummy? No other modules are needed sometimes. no firmware downloads are needed. Thanks, Jerry

Hi, Vinicius, did you actually solve the choppy audio issue by compiling Gordon's kernel? I have the same problem on the exact same Alix platform (using kernel 2.6.31, though). regards, Darko ps.

Hi, I need to run ztdummy for Paging, but now that this is all become dahdi I don`t really know where to start. I did build dahdi before building asterisk, but that`s it. I find it hard to find any documentation referring to dadhi instead of zaptel. I have no Digium hardware, but I still need the ztdummy timer (or whatever it`s called now). How do I get myself going? Regards,

Howdy, I am playing around with asterisk within an LXC container on Ubuntu 11.04. I have asterisk (1.4.42) running fine, but want access to dahdi_dummy for timing (meetme).
