Hi! We have CM 6.x. We like to change DHCP server to manual settings on the IP extensions ( All IP ext s 9650 C) . In DHCP server in the Option 242 -in tis moment- there is 3 IP ADDR for Call server: 1 for main server, 1 for ESS, and 1 for LSP. If I set the phone by manual, there is only 1 IP ADDR for call server. How can I set the other 2 call server addr?
