Hello, I am relatively new to Asterisk and I need to compile the G.723.1 codec for Asterisk. I downloaded the ITU source code, placed it in the codecs directory, but apparently Asterisk needs a rather different library than the one provided from ITU. As I've seen in the mailing list archives, there are quite a few users who were able to compile G.723.1 in *, so, could someone kindly share it with me in order to be able to use this codec? Thanks in advance, Achilles. -------------- next part -------------- An HTML attachment was scrubbed...

Even simple asterisk server is $30,000 per server). http://www.dspg.com/technology/LicensePricing.html Of course someone outside US could get this working (software patents are currently only a US phenomenon) but there's no way that it'd get into the asterisk tree as I believe digium are US based.

[Asterisk-Users] Re: Compiling Asterisk with G.723.1
Hello, I understand these licensing issues very well. I don't reside in the US, so I assume that there is no problem, especially for testing/development, and not commercial use. What I was asking however, is whether there is an alternative G.723.1 library which compiles with asterisk other than the one we can find on the ITU website. Thanks for any suggestions, Achilles. -------------- next part -------------- An HTML attachment was scrubbed...

There are many people/companies/organizations who need G723.1. Although apparently it's not a problem using a patented codec like G723.1 outside of the USA, most of us would gladly pay a reasonable per-channel fee for it's usage, like in the case of the G729 which Digium offers. But since it is not available in this manner, I think it's only fair to provide the source code for compilation/usage at least outside of the US. I know that quite a few Asterisk users have compiled G723.1 in their box. Like many others, I would like to have this code and be able to compile it in my box. In fact, many of us would even pay a reasonable sum in order to have the code, if the people who already have it & use it in their boxes are not willing to share for free.
