Actually i'm wondering why the differences in calculating bandwidth required for G711 & G729 in CCM & GK
CCM calculates :
G711 ---- 128 kbps
G729 ---- 24 kbps
While in GK :
G711 --- 64 kbps
G729 --- 16 kbps

well, let's start with the right information because what you posted is wrong
CCM
G711 80 kbps
G729 24 kbps
GK
g711 128 kbps
G729 16 kbps
CCM takes RTP + L2 overhead
GK only RTP BW required for 2 way communication with no overhead of any layer
you can play around with the BW calculator to get a better grip of this

I'm sorry for that,i send this post when i was very tired.
Is that right behaviour from GK to calculate G711 call as 128 while it takes only 64 per call?Why GK do that?
Could you explain?

yes. it's the right behavior and a call does take 128 kbps, 64 EACH way unless you want 1 way audio
there is no explanation for this other than different groups developed each product and they decided it like that separately
