[asterisk-biz] Looking for Mexico Mobile Provider

[Bryant Zimmerman]

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. 

We have 6 carriers we currently direct trunk with 4 out of the 6 send and 
receive g729
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.

Thanks
Bryant

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.
