If you're using Asterisk 1.2.x, dropcount, jittershrinkrate and
minexcesbuffer don't do anything.  They are ignored by 1.2.x unless
you specify that you want to use the old 1.0.x jitterbuffer.  Instead
you might try the parameters maxjitterbuffer, resyncthreshold, and
maxjitterinterps.  For more, you can check out the sample iax.conf.

I believe, also, that you are correct in setting trunk=no.  I know in
the 1.0.x jitterbuffer, trunk was not fully supported.  I think this
is still the case with the 1.2.x jitterbuffer.
