hi richard!
here is my configuration for InterVoip.com. please notice that I am using "sip.voipcheap.com" then with InterVoip sip server it does not work.
maybe cann help you.
EDIT:
1) check twice username and password!
2) Click on Dial Plan List and enter some number and test the call (click "TestCall").
maybe you have some syntax error in regular expression for dial plans.
3) are *500 and *600 working for you?
but betamax is ........ not so easy to understand
.
regards,
fla
