Thanks for the info, and please forgive my ignorance on the subject...
Is there a standard that ATAs uses for codec selection?
Yes SIP/SDP check the RFCs.
Like everyone else, I want to make sure my ATAs (cisco, sipura,
linksys) use only lower bandwidth codecs. I can guarantee that my
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
reason.
You cannot enforce any codec selection with MediaProxy, you can only
limit/order the codecs in the PSTN gateway or your user agents.

Daryl,
MediaProxy relays only RTP/RTCP packets irrespective of the codes
negotiated by the end points. So your endpoints select the codec
based on SDP offer/answer model and not MediaProxy.

How does mediaproxy select the codec to be used when multiple are
present?
Does it try to use the lowest bandwidth codec first?
Is there any way to manipulate this so if it finds 3-4 codecs
available, it will use the one specified?
