The way around it is to either rely on a disclaimer telling the user its up to him or her and then hope no lawyer comes calling... the other way would be to have a market version with a pricetag covering the patent fee. This might not actually be such a bad idea but it would require a license deal from someplace other the sipro since they charge some ridiculous initial amount just to sign up. Maybe something like http://www.synapseglobal.com/g729_codec_license.html
But I guess that begs the question if anyone would actually pay 10-15 bucks to get a version containing G729...

For the license part.... it's more complicated.
I agree with micheal's comment and that's also what Samuel explained to me.
Thanks a lot micheal for the SynapseGlobal link. I didn't know that there where retailers that allow a per license purchase. Really interesting !! It could be easier to manage than the sipro solution that afraid me a lot !!!

In the case I get a solution to manage the license, the best solution is to provide a plugin app on the market that provide an updated version of the dynamic library. Some changes has to be done in the update process but that was already planned.

This method will sip providers to provide their own application that relies on CSipSimple and include a g729 library if they already pay fees for their users.

There is one thing I miss to be able to test... Allow local accounts (because all my registrar rewrite invite offers and doesn't allow g729 :D ).
I'm pretty confident in the fact that it will work, but I don't know what will be the performances.
In fact, for the Iphone version, it was possible to use assembler code, but for android, since we commonly use a aebi assembler, instructions are not the same, so I fall back to generic code. Less efficient but that build within the NDK.

For now, my priority is to implement filters and rewriting rules for native dialer intergration. But I continue this task in background.

Well, thanks for your nice proposition egcrosser but I've just succeeded using one of my sip server without SBC.

So after many tests (there is still bugs with the codec priority management), my calls between a HTC Sapphire (Magic / G2) and Nexus One using G729. (Both handset use wifi)

Result is pretty good. Latency is really low. Sometimes (probably due to VAD) I get some choppy sound on the G2 but sound is clear on Nexus One.

So it's worth to be continued. For now what I did is just unreleasable : I made code to allow compilation at midnight... But I'll try to do something more clean, and contribute it back to Samuel's Siphon project once it will be enough clean. And of course it will be available on my repo.

Meanwhile, I'll get more information about how to solve this licensing issue. SynapseGlobal sounds a good solution, but give license for special implementation (such as Asterisk's one). And there is maybe a little trick with the fact that a exception to GPL has to be added in code license to allow the *distribution* with the G729 license.
