Hello I'm thinking of selling an Asterisk server based on Atcom's IP02 solid-state unit with one FXO and one FXS ports: http://atcom.cn/En_products_IP02.htm By default, this unit based on a 400MHz Blackfin 532 chip only has 64MB RAM and 256MB of NAND flash. Those can be increased to 128MB and 1GB, respectively. Do you think I can install Linux + Asterisk + LAMP (replacing MySQL with

Hi All, I have followed below steps to enable echo cancellation. # cd /usr/src # wget http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.28.tar.bz2 # tar xjf linux-2.6.28.tar.bz2 # tar zxvf dahdi-linux-2.1.0.4.tar.gz # ln -s /usr/src/dahdi-linux-2.1.0.4 /usr/src/dahdi # mkdir /usr/src/dahdi/drivers/staging # cp -fR /usr/src/linux-2.6.28/drivers/staging/echo /usr/src/dahdi/drivers/staging # sed -i

Hello all, I'm a hardware person who has recently found himself thrust into a software role. So, please forgive any ignorance in the following questions. I've tried to do my homework reading the relevant manual pages and investigating the Doxygen documentation. :-) We're investigating acoustic echo cancellation solutions for a speech application. Our hardware will be a TI C64x+

Hi Jean-Marc I'm trying to integrate your speex codec on our custom Blackfin board. The board is not uCLinux compatible and there is no chance that it will ever be. I am using ADI-supplied VisualDSP++ IDE and corresponding toolchain. As long as I am compiling "C"-only version of the library everything is fine. VisualDSP++ produces working library. There is only one not so minor

Hey all, I have a potential project which calls for a very small form-factor computer like this: http://www.marvell.com/products/embedded_processors/developer/kirkwood/sheevaplug.jsp However, I am needing an FXS port integrated into a small footprint computer. Nothing larger than a WiFi router or gateway device, but the smaller the better, and able to run Asterisk with at least a spare USB port

Hi all, After reading great things about the OSLEC Echo Canceller (http://www.rowetel.com/ucasterisk/oslec) and seeing the reactions of people who have tried it on a recent Trixbox thread (http://www.trixbox.org/forums/trixbox-forums/open-discussion/need-people-echo-problems), it sounds like it is the "bees knees" for sorting out echo problems with cards like the x100p. Has anyone

Yesterday I pulled in the latest svn of Dahdi and added the files from a recent kernel in the drivers/staging/echo structure and modified the Kbuild file so it would compile without error. I insmod'ed the module in, and modified my system.conf has echocanceller=oslec. cat /proc/dahdi/1 shows: Span 1: WCTDM/0 "Wildcard TDM410P Board 1" (MASTER) IRQ misses: 1 1

Hi - I've got a new install with a Sangoma A200 and a few GXP2000's. When users are talking over the Sangoma, they get a lot of sidetone (local echo). Internal calls are fine. Where do I adjust that? I assume its in zapata.conf somewhere? thanks Todd

Hello, We're about to deploy an Asterisk system. So far we have the following (below) configuration but before we start anything we would like to hear some suggestions on it, specification or recommendation too... Thank you! miniITX board dual core CPU 2 LAN 1x IDE (or more) 2x SATA (or more) 2x PCI slots (must work with Linux correctly in regards to IRQs) Optional: On board hardware RAID

Hello To run Asterisk on an embedded appliance, ie. where RAM and non-volatile memory is an issue (respectively 64MB and 256MB), I need to check how much space voice messages take to save and play back. The appliance is connected to a landline in Europe (in case that makes a difference as far as codecs are concerned). Is there a document that shows the different options, with/without

Greetings everyone, I'm trying to compile asterisk for an AVR32 (Atmel NGW100). Buildroot for AVR32 already has the asterisk package, though it has bugs. Firstly it tries to apply a patch for 1.2 on a 1.6, but deleting the contents of the patch file did the trick. Now, the problem is making asterisk. The first error is because asterisk needed to be ./configure:ed. Trying to just do

Hi, I'd like to try using a good quality microphone and a set of PC speakers (in the first instance) to create a powerful speakerphone; if I get that working, I'll probably try more elaborate audio equipment. For this to work, I'll need software acoustic echo cancellation, or the caller at the other end will constantly hear his/her voice echoing back. I gather Asterisk can do

Hello I'd like to configure Asterisk so that... 1. I ring it from my cellphone with CID number displayed, just to notify Asterisk that I wish to make a call 2. Asterisk waits until I hang up, calls me back, and prompts me for the number I wish to call 3. Asterisk puts me on hold through Flash(), which is apparently the equivalent of hitting the R key on European handsets 4. Asterisk calls the

Which we are constantly working on. We do have some targetted pieces of C code, that we noticed could be done better, and are in process of working on. -Robin

Dear All, How can we know the On board supports echo cancellation I have *Digium, Inc. Wildcard TE410P quad-span T1/E1/J1 card 3.3V (rev 02)*board all working fine but sometimes i got echo when user are calling a PRI. is there any way to know on board echo cancellation . regards Dhaval -------------- next part -------------- An HTML attachment was scrubbed...

Hello I'm taking a look at how to write scripts to be called from the dialplan, and saw pbx_lua mentioned. I'd like to know more about this feature, such as what the difference is with just calling the Lua interpreter through AGI (same difference as between php-cgi and mod_php?), whether it's production-ready, etc. Thank you for any help.

> >Actually, you're the first I know using the VisualDSP++ toolchain :-) > I guess that's because speex has pretty big memory footprint. So developers that integrate speex tend to have plenty of RAM and once one has plenty of RAM he could install biggish OS. And between biggish OSes for Blackfin the most popular choice is uCLinux. And ucLinux works best with gnu tools. Something

Hi all, I am interested in using the OPUS codec for real-time application on an (preferable low-profile) platform. In order to choose the optimal processor (memory size, speed,...) I have the following questions: - We have compiled OPUS on a PC with Linux OS and on a dual-core Cortex A9 with Linux Kernel. Can OPUS run on a processor with no specific OS, or are there
