And second thing is that if i have a wave file then wat is the way to play it by using these codecs,, like i have a wave file and i have download G.729 , now how i can play this wave file by using this codec G.729?
Do you have experience configuring and tuning QoS for a VoIP solution through the internet. I mean setting Jitter settings and such. I have a VoIP solution that I have implemented recently and at times it is good and other times it is crappy. I am having trouble tuning since it is such a new technology.
