Do bristuffed zaptel (zaphfc) supporting rxgain/txgain in zapata.conf? I'm changing rxgain in zapata.conf, and reloading zaptel, but sound level on ISDN(HFC) is always the same (loud).

...I am feeling extra stupid this Monday morning and am hoping someone can come to the rescue. I am trying to use the ztmonitor utility on my wildfire 4 FXO card. and have read the following from the wiki. *********Wiki start******** If you set this to yes, use ztmonitor to adjust the rxgain and txgain. Ztmonitor isn't installed by default; but it is included with the Zaptel source code, so look in /usr/src/zaptel. Use ztmonitor like this: ?./ztmonitor?1?-v ?Rx?##################################Tx Place a call, let the remote party talk, then adjust them until they sound better. For ex...

In trying to get the asterisk and faxing working I had to resolve to using iaxmodem and hylafax. I have incoming working, but outgoing the other fax rings but it would appear from web searches that the fax signals are too low to be "heard" I can read about rxgain and txgain for zapata. my fax setup goes direct from aterisk <-SIP-> SIP Provider <- Fax Machine -> It never touches my FXS and FXO card. Thanks in advance Barry

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...

...hem (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 jump up and down. For some lines the values vary around 440, for others around 250 and for one of the unused FXO ports, its around 97 all the time. With txgain/rxgain set to 0.0, call volumes were considerably low. Hence, I have txgain set to 1.0 and rxgain set to 6.0. I was wondering if the ztmonitor Rx: values were normal for what they show, or are they too supposed to settle down to 0. If this is not normal, does this indicate any problems with the po...

Hi I have a server with the last version of asterisk branches, zaptel branches, 2 Digium Card with TDM800P 16 HPEC channels (Echo Cancelation), 40 Grandstream BT200 and 10 Grandstream GXP2000. zapata.conf echocancel=64 rxgain=0 txgain=0 when i place a call o receive a call, I finish a sentence i hear a ssssssss, AND when the both side talks at the same time i have choppy audio. Any help i appreciate. Thanks Ruben

I am finding that I have to increase the txgain in zapata.conf to 8 when my X101P is connected to my BT phone line, otherwise people can hardly hear me. This then gives echo issues. Do other people have the same problem on BT lines. I was wondering if I should give BT a call and get them to increase the gain on the line. Strange though as the r...

Hi, Do you have some experience with the "best" values for those parameters in youyr particular case? I mean the best raport between sound level in both direction and echo cancellation. For me, the best result I can get is with: rxgain=10 txgain=15 ... the sound level is good, but the echo is a little bit to strong for my taste. Something interesting is that if I put a txgain value greater than 15 (let's say 20), the external dial through X100P is not corrrect anymore. I get from the PSTN operator the message " the number you hav...

Is there an option txgain for SIP in Asterisk? My users all complain that their other parties think that they are way too silent even though they all have their mic volume all the way up and also enabled the 'mic boost' option. This happens with all the clients that we're using and also with different model...

Hi, does anyone have test numbers in Germany that would allow me to tune my rxgain/txgain settings? I know there are numbers provided by other providers in UK e.g. but have yet failed to find a number in Germany (esp. by Deutsche Telekom). Kind regards, JP

Is it possible to adjust the rx/txgain values per device? I have a mishmash of different phones (soft phones & sip hard phones) and each of them sound different w/the same rx/txgain settings. Is there any way to adjust these via asterisk? I'm having the most difficulty with sjphone & these zultys zip2 phones, vol is right on...

...ust 12 or so feet away. When you put an analog handset on the line, both the RX and TX volume seem to be just fine. However, when I use the TDM card, I have to have an rxgain of 13.5, and even then, the audio is relatively quiet. I'm also getting echo on these lines, so I have turned the txgain down as low as I can and still be heard. Right now, it's at -6, but it will have to come up some because that is too quiet. But I still have echo. I am in the middle of trying to get a milliwatt test line to calibrate the rxgain properly. However, this won't help me with the txgain,...

Hi all, I have a brand new TDMxxx card with 3 FXO modules and one FXS. It has replaced my old 3 X100P cards. The FXO part work as before, after some adjustments in the rxgain/txgain part. The problem I have is with the FXS module. I can place calls to SIP/IAX or PSTN destinations without any problems, but the sound received by the other part is much to strong and a little bit distorted. I have tried to modify the txgain up to txgain=-20, but still too strong. ..and this is...

I am looking for docs on how to diagnose and adjust the rx/tx gain in zapata.conf. The wiki has a link to this article but it no longer exists on the server. http://lists.digium.com/pipermail/asterisk-users/2004-November/071301.html

...oming or outgoing calls I can hear the other party ok but when I speak, I hear my voice echo back at me (quite quietly but it's distracting!) on everything I say. The other party doesn't seem to hear the echo - they just say I sound a bit quiet. Someone suggested I play with the rxgain and txgain but this didn't seem to help. Is there anything I can do? - or is it a problem with my fxo card or zaptel cards in general? I'm running Asterisk 1.0.2-2 on Debain Linux (with zaptel 1.0.0-2) and i've got the modem connected to an NTL phone line in the UK. Here is my config's: /etc...

Hi all, I have a TDM400 with all FXO on it. When I make an outgoing call, I can hear callee but callee claims the volume is too low so that he/she can't hear very clear. Can I adjust to increase the volume in callee side? Is it increase the value of txgain can solve the problem? ango
