<span style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt">No stats but when we shifted to the big carriers the prefered format for most of them changed to g729. They will send or accept either but if we offer or accept g729 first they will take it. It is great as it cut our bandwidth foot print. Some of the smaller carriers still don't support g729. We are a small carrier and we push the g729 where ever possible. Thank you Digium for fully supporting g729 in both software and hardware. <br />
<br />
We have 6 carriers we currently direct trunk with 4 out of the 6 send and receive g729<br />
The four are all big name US carriers. The other two are good sized but not big name. When I challenged one of them on this issue I found out for some reason they convert 80% of the calls flowing in from g729 but will not send or accept g729 this one perplexes me but apparently some of their gear won't support anything but g711. The other carrier won't comment.<br />
<br />
Thanks<br />

<br />
Does anyone have stats on that? I must admit, I was very much under the impression that most commercial VoIP carriers were using g.711 far more than any other codec choice.<br />
