A VoIP provider ask me to do some task on making VoIP enabled phones like Nokia work for them. I Have N80 and E65 unit and I am trying to configure the SIP settings on the phones using their SIP server generated User name, password and SIP server address but it is not giving me a “registered” status. i tried installing a 3rd party software like fring or truphone, that is the time I can make an internet call when I’m in a WifI zone.
Do you have any instructions for this matter? or whats the trick behind it? They might get a bunch of phones if this project work.

Thanks in advance!
