Hi, its probably written a thousand times through the forums, I just cant find it. If I want to use G711 codec for my NodePhone which one should I use a or u?.

I know it uses a lot more bandwidth , but for better calls it must be worth it?

thanks.

We'll allow you to do both. G711a is prefered as it doesn't require transcoding when it hits the traditional PSTN in Australia. ("U" is the companding method used in the US/Japan, the rest of the world uses "A" in the PSTN).

Thanks, that was quick.

Is it true that this codec should only be used if you are on a 1500k plan or its ok on a 512k plan as well?

It'll be okay on 512kbps if you're not using it for anything else. (G711alaw/ulaw uses around 80kbps in total).

thanks again.

Cheers.

And it's still fine if you've got decent QoS enabled (I can run bittorrent pretty hard, and it still doesn't effect my calls on a 512/128 plan with G711a on a Billion 7401VGP).
