[cisco-voip] Gatekeeper CAC with bandwidth

[Yinglam Cheung]

I have a problem with gatekeeper doing call admission control with
bandwidth. Basically I have CCM 3.3(2) and CCME configured as H323 gateways
in the same zone with gatekeeper. G729r8 is used for calls between phones in
CCM and CCME.
 
Without enforcing bandwidth control, I can see bandwidth for a call is
16kbps:
 
GK#sh gatek zone st
                         GATEKEEPER ZONES
                         ================
GK name      Domain Name   RAS Address     PORT  FLAGS
-------      -----------   -----------     ----- -----
 
Zone1         xyz.com     192.168.1.1   1719  LS
  BANDWIDTH INFORMATION (kbps) :
    Maximum total bandwidth : unlimited
    Current total bandwidth : 16
    Maximum interzone bandwidth : unlimited
    Current interzone bandwidth : 0
    Maximum session bandwidth : unlimited
    Total number of concurrent calls : 1
  SUBNET ATTRIBUTES :
 
however, if I want to allow only 5 g729r8 calls  from CCME site to CCM with
command:
bandwidth total zone Zone1 80
 
OR 
 
bandwidth total default 80
 
then the call from CCME site to CCM got a reorder tone, why is that? I
figured out I have to configure at least 128kbps in the command to allow
g729 call.  Is it possible to do this for multiple sites within the same
zone? 
 
calls from CCM to CCME seems fine.
