I have a customer who has an IPCCX 4.0(2) custer with two nodes one active and one passive. The Customer now requires a DR Site. Since IPCCX is not designed for WAN Failover i had told him its not Advisable to have 1 node at Main Site and 1 node at DR. Instead i had proposed a Standby server at The DR site which would be ready with IPCCX installed and only when the site is down the configuration would be restored to this server and it would registed with a Call Manager Subscriber local to the site. What i need to know is whether the License that is already there with customer for their Existing IPCCX can be used for this standby server?
