create...got it...that means that if i have a phone registered in proxy A,
and i want to call userB, A has no idea where B resides, at all...how does A
know the domain of B? he must put in the RURI of the invite
userB@domain_of_b, right? how does A knows the domain of B? does A must
press in the phone: usearB(a number)@DOMAIN_OF_B?

sorry for many questions, keep reading the rfc...
