UCM6510 IP PBX User Manual
Version 1.0.20.31
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.
