Dear all:

I have some questions about the G729 codec. I will be appreciated if someone could help me.

1. If I want to modify the G729 codec, I must compile the module and substitute for the original one. Is it correct?

2. It seems that there is an authentication server for G729. Should I need authentication when I use the modified G729 codec?

3. If I want to add my codec which is not in core, how to do it?

Thanks for helping.
