How much bandwidth does an Intercluster (not intracluster) link need?
Can this work over a site to site vpn?
Will an intercluster trunk work if one cluster is running 4.1 and the other is running 6.1?
thanks in advance
There is no replication between different clusters and no Keepalives. I've ICT working between different countries without any issue. The Trunk is a kind of hook created at one end to throw calls over to next party (i.e. next cluster). The only b/w required would be for calls.
yes it will work
for BW it will depend the codec u configure between ICT
