S McGowan,

I don't know if you missed my question (from the slew of questions you've
received and answered), but I was wondering about transcoding and PSTN
channels. What kind of codecs were used and was there any transcoding
happening? Was this box only responsible for VoIP-to-VoIP calls or was
there also PSTN trunks as well? Again, I'm amazed by this example since it
seems to be way over what anyone else normally reports as usable.

Thanks again,
