Hello, I need to convert the dahdi_monitor output to dBm0, so I can measure Echo Return Loss in dB. I've read a formula that calculate S(k) in ITU-T G.168 recommendation, where S(k) is the signal level in dBm0. Can I use this formula to convert it? If yes, what value should I use to the number of samples if I want to convert a single ou...

I am studying about echo cancellation in asterisk and I want to use the numeric information from dahdi_monitor verbose for my research. Unfortunately, I couldn't find anything about the unit of measurement used in this tool. Which unit is used to measure the signal level? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/atta...

hi group , i am working on dahdi_monitor for measuring voice quality , so i want to know that on which data i can tell that this PRI lines are working properly, is there any measurement on basis of that i can make MOS. i am working from last 2-3 days but i only get idea about making .raw file and making .wav file and visulal mode of RX an...

Hi, Using 1.4.26.1 & DAHDI 2.2.0.2, FSK VMWI devices off a TDM840 work fine. With 1.6.1.[45] & same DAHDI, instead of the FSK spill I get a line polarity reversal. Stutter dialtone is generated as expected. Has anyone else seen this? Is there anything special I need to do for 1.6.1 to make FSK MWI work? Thanks, --Barry

Hi dears, I am from saudi arabia and using asterisk 1.6.2.13,Dahdi-2.3.0 and Digium, Inc. Wildcard AEX800 8-port analog card (PCI-Express) . I am facing problem with detecting caller id before first ring.I recorded the dahdi channel using dahdi_monitor command. Where I am able to see and hear caller-id dtmf tones. Pl tell me the procedure to upload recorded file if you needed. Something I want to dig it and make it work in asterisk. Thanks & Regards, Ashik

A previous issue has popped up and once again I'm out of ideas. During the evenings it seems that the TDM channels will spike (dahdi_monitor) and will refuse to listen for audio of any type, this includes DTMF. The only resolution I know of is to stop Asterisk and restart the dahdi service, but that's not a solution. All channels look like this, even the FXS. [root at asterisk Hardware]# dahdi_monitor 1 -vv Visual Audio Levels. -...

Now that I have a new card and my echo problems are 'mostly' solved, I have another major issue to deal with. After about an hour or so the card will stop detecting DTMF tones on incoming calls. dahdi_monitor shows the following: [root at asterisk wctdm24xxp]# dahdi_monitor 1 -v Visual Audio Levels. -------------------- Use chan_dahdi.conf file to adjust the gains if needed. ( # = Audio Level * = Max Audio Hit ) <----------------(RX <----------------(TX ###################################*...

...a difference (I tuned RX down to -6.5 per the article here: http://www.voip-info.org/wiki/view/Asterisk+zapata+gain+adjustment so that the RX is at around 50%. I haven't found a good way to do TX tuning, as setting it via 'dahdi set swgain tx' doesn't seem to have any effect on the dahdi_monitor output). I've enabled fax debugging (fax set debug on), but that doesn't seem to do anything either (perhaps I need to raise asterisk's debug level as well?). What steps should I try next?

Hello, I just made a asterisk / dahdi fresh install on Debian 8.4, and ended up with the following packages : $ sudo dpkg -l|grep -Ei 'dahdi|asterisk|libpri' ii asterisk 1:11.13.1~dfsg-2+b1 amd64 Open Source Private Branch Exchange (PBX) ii asterisk-config 1:11.13.1~dfsg-2 all Configuration

Hello again list, I'm running a 1.4.42 install on SUSE with an AEX410P card. The DAHDI release is 2.4.0 because the machine won't properly install 2.5 and also won't install Asterisk 10.0 because I can't get a good SQLite3 library to install. Whenever I enter DTMF very quickly or very slowly, app_read des on me. Has anyone experienced similar joy

Hi All; In dahdi: what we use instead of ztcfg -vv (that is existed /sbin/ztcfg -vv). ? Regards Bilal

...e alot of issues that can happen once the call leaves the office that I will never be able to address (vonage, cell phones, etc) but I am trying to see if there is anything I could do to help alleviate the issue on my end. I never really messed with rxgain and txgain and was starting to play with dahdi_monitor to see my gain levels... Do you all think this could be a gain level issue?

Hello I am working on TDM2400p. I am having some problems like: when i connect my analog phone with the card there is no dial tone, but i can dial any extension... but after that i can't hear any voice from my receiver i have used different phone sets but still i cant communicate with other extension. Please help me out. Thank you Regards Ali Raza -------------- next part -------------- An

Hi All, I have set following milliwatt and dial in from my mobile phone. and i adjust txgain value in chan_dahdi.conf but no effect on dahdi_monitor value is same. even i change its to 20 and more but monitor still showing same value. But i can hear tone variation on my mobile when i am changing txgain... is there any specific value i can set in txgain or leave it default 0.0 ( # = Audio Level * = Max Audio Hit ) <----------------(RX)----...

...;s the problem: In the Echo test, pressing the # key does not terminate the action -- audio just stops, I never hear the "good-bye" message, and I have to hang up. The same thing happens if I press any other key on the phone besides #. But in the Record test, it all works fine. I used dahdi_monitor to try to debug this, and found that during dialing the extension, each DTMF tone lasts about 100ms. But whatever DTMF is sent during the Echo test (# or anything else) gets cut off at about 70ms, and that tone is then transmitted continuously on the channel until I hang up, even though I don'...

Hello, I am working on a trixbox based system with a TDM410P connected to 3 phone lines from the CO. The asterisk box is on a full duplex 100Mb LAN with some polycom and Aastra SIP phones. In general everything works. the problem I am trying to solve is that if both parties to a call speak at the same time one of the voices gets cut out such that the talker A cannot hear what talker B is
