[Users] codec translation

[Andreas Granig]

Hi,

rtpproxy and mediaproxy do media-relaying and OpenSER does SIP routing. 
Both have nothing to do with codecs, which are negotiated end-to-end. So 
yes, OpenSER and rtpproxy/mediaproxy do support G729 in a sense that 
they allow UACs to communicate with G729. If you want to transcode 
between codecs (e.g. G711 <-> G729), you need - as Daniel already said - 
a transcoder like Asterisk.
