similar to: Poor sound quality on ISDN BRI calls

Hi, I solved the Problem: the context defined in zaptel.conf: context = zapincoming was not in extensions.conf, so nothing worked. ( I assumend this context is only necessary for calls from zaptel, not to it) This may be a bug: in the verbose log I found nothing like "[chan_zap] Could not initialize ..., due to ....", this had helped alot and had saved alot of hours (-;

Using the latest(?) bristuff (Asterisk 1.0.4-BRIstuffed-0.2.0-RC3a) I have problems with loosing the D-channel. Most of the time, after the message "PRI D-channel down" it only takes a second or so to come back up, noted by the message "PRI D-channel up" However, today most of the time the D-channel stays down. Calls come in, but can't be answered. Does anyone know

hi, I am on fax-to-email system, basically taken from http://www.voip-info.org/wiki-Asterisk+Fax+to+email well, it seems that asterisk causes some problems so that it is impossible to send any fax. I.e. when I try to send a fax to asterisk (rxfax application): normalFax--->FXS(TDM400P)--->Asterisk(RxFax) it breakes up the trasmission at the beginning of sending page. The code given by

Hello, I tried to read Bristuff source code to understand the way calls are bridged from one BRI port to another (as HFC cards have "active channel switching capability"). Doing so I looked at zaphfc.c file which seems to be the only .c file constituting bristuff but I may be wrong I'm far from being an expert on this. I found 4 functions (hfc_btrans, hfc_brec, hfc_dtrans,

Hi, I'm banging my head on compiling bristuff modules for Suse 10.0 with kernel : Linux laps1 2.6.13-15.7-smp #1 SMP Tue Nov 29 14:32:29 UTC 2005 x86_64 x86_64 x86_64 GNU/Linux and Asterisk 1.2.1-BRIstuffed-0.3.0-PRE-1f .

I have a problem with Asterisk-bristuffed using a zaphfc card. I am located in the Netherlands, so I have an ISDN line from KPN. When I start Asterisk, and plug in the ISDN line, everything works perfectly for about 5 minutes. And then the ISDN line is down for 1 minute, and after that minute, the line comes back up and works for another 5 minutes. Every time the line goes down I get the error

Hi, Bristuff works great with HFC card... your compilation problem may come from your kernel configuration... You should check this doc, at least, for the redhat config : http://www.automated.it/guidetoasterisk.htm Then, installation of Bristuff works like as charm !

Hello * users I've problems with sound quality on zaphfc Asterisk works fine good sound quality. If I do "make load" in the bristuf.xx zaphfc dir then sound quality drops directly. Even if I don't load the chan_zap in the modules.conf I use this config on more (even old 400Mhz machines) and works correctly. Looks like an hardware problem but I can't find it. I don't

I would like to know how to install asterisk 1.0.9 with zaphfc working on a SuSE 9.2. I tried this: - The rpms with SuSE 9.2 are asterisk 1.0.6 - bristuff works, except for zaphfc, which doesn't compile. - The official asterisk download file doesn't contain isdn bri support Any ideas?

Hello I have asterisk running in Red Hat 9 with a cheap HFC card on i4l. I have choppy sound problems sometimes, and echo problems often. I am using a 2 port Grandstream ATA, Grandstream BT and a Grandstream GPX-2000 I read that changing to BriStuff will fix the echo problems, but have also read other users say that the only way they solved the echo/choppy sound problems was using a Fritz ISDN

Hi, it helps to have configured and working kernel sources installed. Configure your kernel sources for the running kernel and then run "make" in the kernel source dir to build the necessary scripts. You dont have to wait until the kernel is compiled. best regards Klaus -- Klaus-Peter Junghanns Am Samstag, den 25.06.2005, 02:45 +0200 schrieb Stefan Gofferje: > Hi folks, > >

I'm trying to take advice to use "zaprtc from bristuff" (from both a posting here and references on voip-info) because I have a 2.4 kernel SMP machine. I've downloaded and installed bristuff-0.2.0-RC3a and now have the modules zaphfc and zaptel loaded. Running meetme says the extension is invalid (I've double checked meetme.conf and extensions.conf). There is no zaprtc

Maybe this is rather a hardware question, but I am posting it on this list because the probability of someone else of you having tried this is greater here than other places I can think of. I have an ISDN card that is setup in NT mode using the zaphfc driver in bristuff, and I got it working perfectly with one ISDN phone using a crossover cable and 100 ohm termination at the end of the cable.

I'm using bristuffed Asterisk with ISDN/ZAPHFC I have VERY ugly (outgoing) sound through ISDN/HFC if echocancel=yes in zapata.conf, but without echocancel I have bad (incoming) echo Through PSTN/FXO sound is ok with or without echocancel. I tried other echo cancellers (in zconfig.h) two times: ECHO_CAN_KB1 (this was default) ECHO_CAN_MARK2 ECHO_CAN_MG2 after any change I compiled (make

Hello, there has been a post to this list somewhere arount april which said that it is possible to use a Sangoma BRI A500 card with zaptel and asterisk bristuff. That is, without sangoma_brid and sangoma_mgd daemons and without woomera channels. Could anybody give me a short hint how to configure this? I tried wanpipe-driver + zaptel + asterisk-bristuffed, but I couldn't get zaptel to
