G729 Purchases


I know that the g729 codec is free to use for personal use or testing but what about if I want to implement it in opensbc, how do I purchase proper licensing for commercial use?

Re: G729 Purchases

How exactly are you planning to use G.729 in OpenSBC? OpenSBC does not transcode. All codecs are passthrough.

Nevertheless, your best option would be to use Digium TC400 boards. It's 120 channel G.729 to PCM transcoder which doesnt require you to buy any license on top of the board cost.

Re: G729 Purchases

I know that it doesn't transcode but doesn't it need the g729 licensing to pass g729? If not, why are all of the other codecs there? I am still trying to find enough information to understand this part of opensbc.

Re: G729 Purchases
No you dont need to license G.729 at all. OpenSBC will passthrough ANY type of codecs. Which other codecs are you referring to?

Re: G729 Purchases

When I looked at the logs after getting things working, I saw;

Seeing the codecs made me wonder if I needed to add g729 in order to use/allow it.

I've been looking for information on this but haven't found anything that explains this well.

Re: G729 Purchases
Ah, I see what you mean. These codecs are for the media server we use internally in Solegy to send audible error anouncements. Unless you are using this feature, you can safely ignore them.
