Hello, I have got a iptel.org SIP account and now i need to configure express talk with my iptel data. I already tried and tried to setup iptel.org sip account on my Express Talk but it always gives me this error: "401 unauthorize". I need to know: how do i avoid that error ? My express talk setup data are correct, i used my iptel.org username, password and sip proxy but it doesn't work. How come ? Bye.
