PLEASE (please) HELP: Cannot get the voicetrading / sipdiscount trial account to work

Hi,

Please help!

I cannot get the trial account (details of which are provided by
voicetrading and sipdiscount on their sites -
http://www.sipdiscount.com/en/freetrial.html ).

I cannot get this SIP account to work... it is supposed to allow free trial
calling of 1 minute in duration to any of their (SIP Discounts currently)
free destinations. Registers fine, calls are all refused with " 403 -
Forbidden ".

Current free destinations are shown on the website (link above)... Australia
is one of them - here is a sample number you could try (probably a good idea
to test with a known good destination number at a destination in their list
of free calling countries to be sure - but in any event... here is the
number I have been testing with [in good faith] and believe is correct /
valid) - Australia --> 00 61 7 3535 3535 .

The (SIP [account]) details are:

User Name: test
Password: test
Domain/Realm: sipdiscount.com
SIP Proxy/registrar: sip.sipdiscount.com

Please, please / ....


Thanks and best wishes,
