[Serusers] How to change Mediaproxy codec g-711a to g-729 or

[Greger V. Teigre]

mediaproxy and rtpproxy are codec-agnostic. They only transmit what they 
receive (yes, also video). The peers negotiate the codec. You need to 
make sure that a) the PSTN GW supports the codec you want to use and b) 
the UA requests the codecs in such a order that the one you want is 
selected (see SDP payload of the INVITE/OK).
