As it is supposed to work today, when creating the outbound channels, if
the format being used by the incoming channel is available on the
outbound channel, that format is supposed to be brought to the top of
the list (made first priority), so that we can minimize the need to
transcode.

If this is not happening, then please open a bug report on
bugs.digium.com, with the details that are needed (Asterisk version,
console log trace, 'sip debug' or packet capture, etc.).
