Hi,

RTP would still flow between the endpoints ( IP phones ) through the gateways and switches as per the call flow and network topology. Call preservation is supported if ccm service is restarted on one of the servers. There is a recent bug which confirms the same about the expected behavior of an ICT call during a ccm service restart
