For transcoding, just make some test calls - some with and some without
transcoding.  If the audio is bad on both, you know it's something besides
transcoding.  Of course, you might want to make the test calls at both busy
and not busy times, which might also help you determine if it's a server
load issue (so occasionally transcoding is too much) or if it's a network
problem.  Ultimately, you would probably benefit from doing some network
traffic monitoring via your routers, and some performance monitoring on
your gateway.  You can never have too much information.
