Urgent: Multiple CCM Cluster with local base call admission
I need help on the following scenario:
I have 3 CCM cluster in 3 different countries (Singapore,Malaysia,Indonesia) forming a fully-mesh H323 Intercluster Trunk.
Each site is limited to max 6 concurrent On-Net call using Location Based Call Admission.
In Singapore, I have configured my Route-List with 2 Route Group to Malaysia. The first is to H323 Intercluster trunk and the second is to the local PSTN gateway.
When WAN link to Malayisa is down or local bandwidth not enough, it will automatically failover to PSTN. But when remote end, Malaysia bandwidth not enough ( i.e Indonesia establish 6 x Voip to Malaysia),it do not failover to PSTN and i get busy tone.
How do i work around this issue to provide the auto failover to PSTN for remote end bandwidth not enough?

answer. Be sure to read the whole thing or e...
