This is Part 2 of the Nokia SIP settings. This time for sipgate.at
(Austria), but it should also work for other SIPGate domains. It has
been hard to get this information from the providers themselves. For
some screenshots check the ENGIN Australia setup entry.

Since I had to look all over�for the correct settings and there was a
lot of trial and error involved (specially for the Realm). Thanks to Engin Support that finally provided this info after logging a support request.

The screenshots are from a Nokia E65, but should be applicable for similar Nokia phones.
