It's a little more complex than that. Remember the Windows one is single-channel only. It's not reentrant and thus totally useless for Asterisk unless you only need one channel. > Otherwise, this process should work and one should be able to create a > working Linux library (along with an asterisk codec).

Speex is really a great thing, but G.729 is the unfortunate standard for communicating with most (proprietary) SIP/H323 devices. If ATA 186's could talk SpeeX this wouldn't be a problem. Trying to get the Windows G.729 code ported to run with Asterisk is definitely barking up the wrong tree though, for both technical and legal reasons. > I think it is rather sad (not to say ridiculous) for a company to guard > a piece of code this small with such monstrous licensing schemes. Amen! Especially when essentially the code is entirely available via the ITU web site for a nominal fee! <not speaking as Digium here>Unfortunately, companies like Voiceage/Sipro who purely are IP licensors apparently have nothing better to do than to try to come up with such rube-goldberg schemes for copy protection, even while demonstrating a remarkable lack of disregard for the actual quality of their implementation (especially in the early days). > Couldn't agree more.

And we sell it because they *have* to have it. I think eventually we'll be able to come up with a better (but not, for the near future, open) G.729 solution from us.
