I am transitioning from a SPA9000 to a UC520. I am trying to still use my SPA VoIP phones, I realize I can't use the Cisco Configuration Assistant to set them up, back I can manually via browser or front panel. I don't see in the running config on the UC520 the IP address or Port number used for the Proxy/Registar functions. The phones receive their IP via DHCP fine, they are in the correct VLAN 100, but they don't/can't register. I used the 10.1.1.1 address with a port of 5060, but that doesn't seem to work. Any help would be appreciated or documentation source.
