I can confirm that, Sangoma's cards do not include AMR licensing. This is one of their * notes right on the marketing materials. Seems the AMR group will only licensed either complete products or the end user. On 3/18/13 10:27 AM, "Steve Underwood" <steveu@coppice.org> wrote:

Hi,

Moises can confirm this, but I think even the Sangoma hardware transcoder cards require separate patent licencing for AMR.

Re: [Freeswitch-users] g729 and AMR codec requirements One per participant. So if you have 500 dynamic rooms w/ 5 participants each you would need 2500 licenses.

Keeping in mind that FreeSWITCH does not have a license for AMR you will need to get that direct from the AMR patent licensing people.

Hi,

I am planing to setup FS based conferencing solutions with 500 dynamic conference rooms with 3 ~ 5 participants in each room.

Need suggestions on hardware dimensioning and codec requirements. I am thinking on using AMR and G729 codecs.

How many codec licenses are required?

Hi, AMR is not an HD codec. There is a wideband version of AMR, called AMR-WB, but when people just says AMR they are talking about the narrow band codec. Steve On 03/19/2013 05:29 AM, Abdul Basit wrote:

What other HD codes are supported? actually blackberry has AMR support only. Thats why AMR should be in the shelf. Also is there any option to buy bulk license for g729 rather than managing 2500 licenses.

Any idea on hardware, CPU and RAM required to deal with such conf. load?

But has anyone actually succeded in obtaining AMR. I am not too crazy about AMR, because improvement over g.729 is very slight. Undernote : can you compile mod_amr for tanscoding against the lib if you don't care about licensing(test/educational purposes)? On Mar 19, 2013 9:31 AM, "Steven Ayre" <steveayre@gmail.com> wrote:

And G729 most definitely is not a HD codec either. :o)

Abdul, have you seen this list of supported codecs? http://wiki.freeswitch.org/wiki/Codecs#Transcodable_codecs

G.722, AMR-WB, SILK, CELT, iSAC, Broadvoice are supported HD codecs.

FreeSWITCH doesn't have any transcoding implementations of AMR-WB. The others do.

For AMR(-WB) you'd need either a 3rd-party software implementation or the Sangoma transcoding hardware. FreeSWITCH's modules can be compiled against a AMR library implementation if you can find that library and obtain the required licenses. If you're worried about load, the Sangoma hardware takes most of the workload off of the CPU onto the chipset. Either way as already noted you're going to have to obtain the AMR licenses yourself.

One that I would consider as an option is Opus. It is basically a successor codec to Speex and CELT, and supports "HD" (or "wideband" and "ultra-wideband") rates/quality. The downside to Opus is that to the best of my knowledge, there is no option for offloading any transcoding onto dedicated trancoder cards or similar hardware. But on the upshot, if you don't need to transcode, it is of little impact to the server that you are hosting your calls on.

Also is there any option to buy bulk license for g729 rather than managing 2500 licenses.

I can't speak authoritatively on this issue, but I think that the bulk option is one stipulated by the patent holder and not by any entity that resells licensing for specific implementations of the g729 codec transcoding implementations. If I recall correctly, you had to have something like an order of 1,000,000 licenses directly from the entity that holds the patent. For a more accurate and correct response, please see the Wiki page at http://wiki.freeswitch.org/wiki/Mod_com_g729 .

Any idea on hardware, CPU and RAM required to deal with such conf. load?

It's probably going to be a heavier load on the CPU than on the RAM. I unfortunately cannot provide any actual numbers, as I have never tested the load. Hope this helps. -Yossi
