If you are using g.729 and sending this with few frames (up to 8) you could reduce BW to less then 13k.
My question is about practical comparation and experience with g.729 and g.723.1 (6.4k)
G.723.1 has MOS 3.7 and g.729 has MOS 3.9, but
g.723.1 is more robust and if you have noisy lines, low Voice level or higher PL, g.723.1 has better overall performances and use 12.7k of BW.
