english help needed for enum

[arnevt]

Hi

I have a german branded 7050.
I enabled the enum options

in internettelephony options, i checked the "use enum".

i registered with e164.org.

the fritzbox doesn't seem to do enum lookups. Have I forgotten something? Will the enum lookup overrule the dialing rules? Will the fritzbox act as a sip client and call directly to the sip address or does he need an sip account?

thanks
Arne
