
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.

PORT FORWORDING

The UCM6510 network interface supports router functions which provides users the ability to do port
forwarding. If the UCM6510 is set to "Route" under web GUI->Settings->Network Settings->Basic
Settings: Method, port forwarding is available for configuration.
The port forwarding configuration is under web GUI->Settings->Network Settings->Port Forwarding
page. Please see related settings in the table below.
