Our customer has 2- 5000s v6.0 networked together working as one system. They have 80 digital extensions , 16 VM ports, 2 PRI, 32 IP phones on one node. 112 digital extensions, 4 VM ports on the other node. They also have CSM, 3 Attendant Consoles, and IP network 4 other locations. The system utilization diagnostics show the CPU is 100% use even after hours when there is minimal activity. Any thoughts? Would it be better to split the systems and have them run independently?
