Thanks for the info, and please forgive my ignorance on the subject...

Is there a standard that ATAs uses for codec selection?

Like everyone else, I want to make sure my ATAs (cisco, sipura,

ATA's and my PSTN gateways will all have g729 available, but I want to
make sure that mediaproxy force a different codec emulation for any
