As above, I installed the Windows SBC and plugged in a Yealink phone. The Phone shows up with the correct private IP address (192.168.128.x) but it says via SBC 169.254.x.x. It does seem to have pulled its configuration but I can't seem to make calls, internal or external, I assume the 169 address is incorrect? The IP on the network card where the Windows SBC is installed is 192.168.128.4 (same subnet as the phone). Any ideas?
