G729 GPL or LGPL?

[Romain]

Hi everybody,

In order to apply to Google Summer Of Code 2009, I am studing G729
implementation for SIP Communicator
http://www.sip-communicator.org/index.php/Development/G729

I saw that you implemented it in Java (\servers\media\core\server-impl
\src\main\java\org\mobicents\media\server\impl\codec\g729). But I
don't know if you protected it under copy-left or not.

Given that, SIP Communicator is under LGPL license, it would be very
usefull to use your implementation of G729.

Cheers

There are special terms for using G729. I don't think it can go under GPL or LGPL. Read more about the restrictions from the G729 inventors' site.

Hi Romain,

G729 is patented codec and hence any and every body has to follow the license term http://www.sipro.com/g729_licterms.php

We just have implemented the Codec however we don't take any bottom line responsibility on its usage as disclaimed here http://www.mobicents.org/products_media_server.html

Thank you

I contacted Sipro a few days ago, they gave me the price if we insert G729 in SIP Communicator. I admit that we couldn't afford such services. (http://www.sipro.com/g729_licterms.php)

So we will give the possibility of using G729 with SIP-Communicator, but we will not integrate it automatically. (We will write some disclaimers and warnings, as you did, and explain a way how to set SP to use G729) . 

Knowing that your are not responsible of G729 usages, could we use your code in SIP-Communicator? (This code is free (Not charging you to use it)).

Cheers

What license do you use for your G729 implementation?

(Hard question I think ;) )

Overall Mobicents is distributed under dual license - GPL or commercial. 

Some specific components such as the G729 codec are distributed under LGPL.
