Hello, I have to create configuration for transcoding AMR <-> G.729/G711. My question is how to do this on freeswitch. I'm searching for some description but it appears it's only for asterisk. I appreciate any help. -- Regards, Michal

You have to pay licenses to use AMR (AFAIK). Then you can use the Sangoma transcoding card (D100, D150, D500 etc) to do the transcoding.

Yes. I'm aware of licensing and Sangoma cards (and I belive I don't need license if use D500) and I'm testing this too but sadly I need also fully software solution to implement on some dedicated vps without physical access. -- Regards, Michal On 2011-08-22 15:01, Moises Silva wrote:

Sadly, for the specific case of AMR, you still need a license even with D500. It is my understanding that the patent holders of AMR did not allow including the licensing from the manufacturer, they rather want to deal with the end user. Note that this is not the case for other codecs such as G.729 Moises Silva Senior Software Engineer, Software Development Manager Sangoma Technologies Inc. | 100 Renfrew Drive, Suite 100, Markham ON L3R 9R6 Canada t. 1 905 474 1990 x128 | e. moy@sangoma.com
I checked this and it seems you may be right - thank you for pointed me to that matter. But still I'm not going forward with software solution to transcoding amr <-> 729/711 ... -- Regards, Michal On 2011-08-23 04:27, Moises Silva wrote:

There appears to be no way for an end user to licence AMR.

I believe I have misused the term "end-user". I meant, our card is not considered an "end-user" product. We did some research regarding this before we started selling our transcoding card. We contacted voice age which is responsible for licensing AMR (http://www.voiceage.com/amr_faqs.php). Because our product is a card and according to their criteria is not and end user product (but rather something that others use to build end-user products), we cannot include the licensing in the card and you have to contact them for licensing terms. I believe that if we were shipping a box with the card included (let's say a PBX) we most likely would be able to include the licensing for AMR. Note also that the license for AMR does not "unlock" any features of the card. The card can do AMR regardless of whether you have a license or not, but it is the same driving a car without a driver's license, you can do it, but it is illegal.

As far as I know, you can't even licence AMR properly from Voice Age. I understand their patent pool is far from complete. Even their G.729 pool licencing, which is far more mature, can leave you getting unexpected letters from lawyers.

In that case how one can do proper licensing ? I didn't found any other company selling AMR Licenses. -- Regards, Michal

Simple answer: one can't. Complex Answer: one has to find all holders of respective rights and make a contract with each group or individual rights holder. Sounds like fun, doesn't it ?

Did you try calling Voice Age? you should discuss this with them. Moises Silva Senior Software Engineer, Software Development Manager Sangoma Technologies Inc. | 100 Renfrew Drive, Suite 100, Markham ON L3R 9R6 Canada t. 1 905 474 1990 x128 | e. moy@sangoma.com

Did you try calling Voice Age? you should discuss this with them. Be warned. Voice Age may not properly inform you about patents outside their pool. This is understandable, if you think about it. To do so would be expressing an opinion about a possibly touchy legal issue.

Steve, Do you have any proof to back this up? Because if not it just sounds like a bunch of FUD to me. On Sun, Aug 28, 2011 at 3:30 AM, Steve Underwood <steveu@coppice.org> wrote:

Voice Age do not claim to represent everyone with a patent relevant to the codes they have pools for. From experience we know more about the handling of the G.729 codec. Voice Age says they represent most of the relevant patent holders. They point you to a couple of the others, which they don't represent. If you use more than the basic features of G.729 you will find lawyers letters arriving about patents Voice Age didn't mention.
