I spoke too soon. If I turn on "inbound-proxy-media", then it goes back 
to "called party can hear calling party, but calling party calling party 
cannot hear called party" (the same as it was before upgrading to the 
latest Polycom firmware), and additionally the calling party now gets 
ringback (didn't before), but if the called party doesn't answer instead 
of dropping to voicemail it goes to fast busy.

The last is probably related to: "[ERR] sofia_glue.c:1608 
sofia_glue_tech_set_codec() No audio codec available" which then fires 
INCOMPATIBLE_DESTINATION.

I also picked up version 11089 *and* threw out all the conf directory 
and regenerated it from the sample source, so this is 100% today-build, 
default-settings (except for the adjustments to inbound-proxy-media).
