Are there any additional steps needed to enable oslec under dahdi, I am guessing I have missed something? Thanks, jlc

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 m...

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+

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

...echo cancellation or acoustic echo cancellation. The Speex echo canceller is optimised for acoustic echo. It'll sort of work on line echo, but it'll be both sub-optimal in terms of quality and more CPU-intensive. For line echo, you might want to have a look at oslec (http://www.rowetel.com/ucasterisk/oslec.html). Cheers, Jean-Marc

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

...l up memory (correct me if I'm wrong). Does anyone have any tips or suggestions, whether I can just remove this limit ? Or is there a better way to dump zaptel traffic for later inspection ?

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 I'm learning how to work with Asterisk on an embedded system (MMU-less Blackfin processor, 64MB RAM and 256MB NAND), and was wondering what people use as scripting language to handle calls through the dialplan and AGI, considering the hardware limitations? Ideally, I'd rather use a rich language like PHP or Python, but can those be fit with even their common modules into such small

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

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...
