[asterisk-users] Some queries on g729 license.

[Al Bochter]

Matthew

I agree. I only know what I have told by others so I do need this input

I have been told that Digum G729 is a big pain the the butt to get 
working with Asterisk
and it is very hard on the CPU

Keep in mind I have never used any Ver. of G 729

So tell me what you think.
