BC11 IP Phone support is really bad, if you want to use them for real and dont want to have problems, you must upgrade.
Are you you using DBC 442 01 or 02? (x02 series will not work in BC11)
phone options can be changed via multiple ways:
to change the network entries, reboot phone and within the first 5 seconds hold keys C*5 (hold them at the same time).
this will enable you to change settings. You can also change settings by browsing towards the phone (password = Ericsson)
