Figure 22: UCM6510 Static Route Sample
The network topology of the above diagram is as below:
• Network 192.168.69.0 has IP phones registered to UCM6510 LAN 1 address
• Network 192.168.40.0 has IP phones registered to UCM6510 LAN 2 address
• Network 192.168.66.0 has IP phones registered to UCM6510 via VPN
• Network 192.168.40.0 has VPN connection established with network 192.168.66.0
In this network, by default the IP phones in network 192.168.69.0 are unable to call IP phones in network
192.168.66.0 when registered on different interfaces on the UCM6510. Therefore, we need configure a
static route on the UCM6510 so that the phones in isolated networks can make calls between each other.
