Hello. I am in the process of moving my callmanager servers to another data center. I have to temporarily leave the IPCC Express server where it is for a couple months.
My question is what are the network SLA requirements for IPCC to be separated from Callmanager? I have looked through the SRND's for information about this but cannot find anything.
Also, does IPCC mark its own DSCP values? I was looking at a network capture and it looks like everything form the IPCC server is marked 0.
The WAN is 50MB with ~40ms RTTs. I have been able to successfully cluster CCM across the WAN with no problems but am finding little information on IPCC. All I've heard is "don't separate IPCC from the publisher".
