Hello Daniele It would be worthwhile to attach an external serial flash or USB thumb drive, if the intent is store data. This allows for far more flexibility in storage Regards Amit On Fri, Aug 26, 2016 at 11:02 AM, Jean-Marc Valin <jmvalin at jmvalin.ca> wrote: > On 26/08/16 11:40 AM, Daniele Barzotti wrote: > > You're right!

Hi, I noticed that speex.org has a banner that mentions that Opus is better than Speex in all aspects. The supported bitrate range for Speex seems to be as low as 2kbps though but Opus can only go as low as 6kbps. Is this one aspect where Speex is still preferred? (I understand that it's not a very common scenario though). Thanks, Manpreet. -------------- next part -------------- An HTML

Hi Jean-Marc, thanks a lot for your reply. > Well, the first question is whether you want encoding, decoding, or > both.

Hello. Voice quality when calling - this is one of the most important in the PBX. You need to record the quality parameters for each call to improve. Because the overall quality of a call can only be determined upon completion, I did it in the HangUp handler and wrote in custom fields of CDR. This worked well in asterisk 11. In asterisk 13 I did not find a handler after the call, but before

First off, I'm sorry for sending so many messages to the list-serv. Hopefully this will be my last for a while! I was going to use my WRT54G router as a small Asterisk box, but I forgot that I had a spare eMachines computer (Intel Celeron 633 MHz, 20GB HD, 64mb RAM). Will this machine work OK for a very simple dedicated home Asterisk box? Also, what is easiest linux distribution to use and

Hi, Anyone know how to set up tftp server for grandstream. I gues it should be somethink like <tftpserver-dir> <mac-address> firmware.bin config.txt Is this correct ? And how should the config-file look like. ? I had search sipphone.com but did'nt find anything. /HHA _________________________________________________________________ Rethink your

Hi folks, I am totally new to audio streaming codecs, and just looking around. Trying to figure out what else I can put on top of my very long list of projects. So a few days ago I figured out that fldigi a digimode application for Amateur Radio supports a dual 1000 Baud PSK mode. I thought "that's fast" and started looking around which sort of Data I could put into that. A

Hi! I?ve just discovered Speex, and sorry if this isn?t the right place to ask this, but I found no other mailing list (some projects have a "users" and a "developers" list separately, I guess this isn?t the case with Speex. If it is, please let me know). First, how I got here: 1. I?m looking for some low-bitrate codec to reduce the size of some very long (think 4-5+ hrs of

Hi all, thanks a lot for your replies! Sorry for my typo, the flash size is 8MB (Byte) :-) Unfortunately I cannot use another flash because I'm working on a proprietary board. Jean-Marc, thanks for your suggestions. I thought to use fixed point for convenience, but I can work on floating point too, so I will take in account the codec2 (I didn't know it). Moreover, if you all have

Hello, I'm trying to use the speex decoder on Windows Mobile 5. I have compiled the debug version of the lib for WM5 PPC. I am running this test on an HTC TyTn phone. I'm decoding 4Kbits narrowband speex audio. Each decode call takes a buffer of size 100 bytes. The problem is that each decode call takes around 130ms to complete. This is too slow for the audio to play back if I stream

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

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

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

Hi All; To overcome the echo problem, what mainly I have to do in the configuration other than the following line in the system.conf under dahdi directory? echocanceller=mg2,1-16 1) How can I know if the digium card supporting echo cancellator? 2) If I am getting a message in the consol that unable to enable the echo cancelator, then what does it means? The hardware is not supporting echo

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

For anything below 6 kb/s, I would actually recommend using codec2 rather than Speex or Opus.

because of problems you are facing i decided to go way with second table CREATE TABLE `cdr_extended` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `uniqueid` varchar(32) NOT NULL DEFAULT '', `callid` varchar(256) NOT NULL DEFAULT '' COMMENT 'sip call-id', `hangupcause` varchar(10) CHARACTER SET utf8 COLLATE utf8_czech_ci NOT NULL COMMENT 'info about

Dear Tariq; About elastix.org, this can be use with Asterisk or it is coming as a complete IP Telephony, Call Center, IVR and Reporting? Because, I do not need to install another IP Telephony on the server which already has asterisk which is an IP Telephony, this will cause a problem in the service (for example, when listening for SIP port of 5060).
