Optimized Codecs for Blackfin DSP
Hi,
Thank you. I will try it. Do you know some G.72x, GSM, and iLBC
optimized for Blackfin ? I mean open source.

Optimized Codecs for Blackfin DSP
Dear Jean,
The source code for G.729 can be download from ITU for free. Also,
some developer can do yourself as open source G.729 codec without any
help. In this case each who use this codec which source code is free
and open source must pay, but not to the developer.

We use now these codecs for x86 in "C" source code running under
Linux. They works very well. My problem is that we are not so familiar
with Blackfin DSP.
Concerning of patent issues, you are not right. The patent is for
their using, not for the source code. Every one

Hi,
As far as I understand, the last patch (for TI C5x) I merged in SVN also
allows Blackfin to work, but I haven't tested.

DSP Coding
Hi,
I would like to find some way for hardware coding instead software
(using the Host CPU). Are there any PCI boards just with codecs (DSP)
or other way?

Help, Ideas and Ready for use Solutions
Hi,
I would like to ask you for advice how to solve the following case:
I have a client (who happened to be my friend) and I have convinced
him that the IP PBX solution is much better than the conventional
telephone centrals (PBX). At the beginning he wanted to buy PBX
Panasonic, but at this moment he is waiting for my decision. Because

How to calculate the price for Asterisk based Solution

We have potential client which would like to offer to him VoIP

License and Commercial Use
Hi,
I can't find anywhere on the Asterisk web the license terms for
commercial use of Asterisk software. Do I have to pay something
(and how much) if I want to use the Asterisk in our IP PBX solutions?

How to use more PCI Cards with FXO/FXS in case that TDMoE doesn't work
Hi,
We have a case where we need of 16 x FXS, 12 x FXO and 1 x E1. To
do this using Digium products I need of 8 PCI slots. This is not
possible to be done in one computer and that's why I try to start
using TDMoE. Unfortunately all my tries are without success. The
network is crashed everytime.
Can you give me some ideas/suggestions how to solve this case?

Outside of GSM full-rate (13 kbps, poor quality), none of these codecs
can ever have open-source implementations due to patent issues. In the
case of iLBC, you can have a free (not open-source) license if you
register, but it's only for the floating-point version AFAIK.

Speex for TI 5509 DSP
I saw a thread in the list archives about a speex port to TI 55x DSP.
Wondering how that worked out (is working out)?
Also wondering if there is a source archive for it,
or if the patch in the email archives is still current, or if there's been
updates.
Any info appreciated.
Thanks

Speex Example Build for TI DSP C54x C55x C6x DSPs
The attached file contains build files for TI's Code Composer Studio (CCS)
for the C54x, C55x, and C6x DSPs. I had intended to post this a couple of
months ago, but it took a long time to get around to doing the little bit of
cleanup required.
This is a file I/O loopback application suitable for running with the CCS

Cisco SIP Phone 7960 & DTMF Problem
Hi,
When we use BudgeTone where the DTMF is set to "via RTP (RFC2833)"
all the DTMF functionality of Asterisk is working OK. When use Cisco
7960 the transfer is working OK, but when I try to "remote pick-up the
call" through '*8#' I can't do that because the Cisco Phone start busy
signal.
How can I start using all DTMF features using Cisco Phone?

Open-Source and Free Software are basically doing the same thing for
different reasons. If something isn't free software, it's not
open-source either. There may be exceptions, but I have yet to

Hardware based DSP
Hi All,
Is it correct to say that by design, asterisk wont make use of any cards
hardware dsp capabilities ?
I don't think that any of the hardware cards currently supported
have any dsp capabilities, but I wanted to know if for example,
in the future a driver was written for a card that did have dsp
capabilities,
would asterisk be able to make any use of it ?
I am only just starting out

Blackfin port on Visual DSP, Michael Shatz ?
Hi,
I'm using the Speex codec on my Blackfin-based board,
and plain-C performance is pretty poor.
Decoder is OK (something 25 MIPS for wide-band).
But Encoder is not (wide-band quality 8, complexity 1):
- 162 MIPS with Analog-Devices lib
- 128 MIPS with 1.2beta2 (faster but not working)
I don't worry that much, as it's not the optimized version, and everything
is running in SDRAM.
