Call admission control with Gatekeeper

I have a CallManager registered with a GK, and I need to implement CAC with G729 codec (16 Kbps).

The GK config :

!
gatekeeper
zone local voiceie ccbootcamp.com 10.10.30.1
alias static 142.5.64.11 1720 gkid voiceie gateway voip ras 142.5.64.11 32779
alias static 142.5.64.10 1720 gkid voiceie gateway voip ras 142.5.64.10 32788 e164 2002 e164 2001 e164 1002 e164 1001
bandwidth total zone voiceie 80
no shutdown
!

According to this, I should make 5 simultaneous calls and every call should be used 16 kbps, but this does not happen. The first call use 0 Kbps. I do not know why

The status is:

HQ#sh gatekeeper cALls
Total number of active calls = 2.

largest hash bucket = 1
