Is it a good idea to use asterisk transcoding from G711 to iLBC or
should I find out any other solution not involving transcoding (f.e.
using G.729 that is supported in both sides). I'm worried about voice
quality and trying to avoid paying for G.729 licensing.

Anybody with experience or quantitative measurements of the voice
quality degradation in that scenario?

The term that may interest you is "Mean Opinion Score" and iLBC is quite good. See http://en.wikipedia.org/wiki/Mean_opinion_score
There's lies, damn lies and mean opinion scores. The chart on that wikipedia page is mostly for humour value.
