Every time I try to set up a SIP account with VoiceMac using the credentials provided by phonepower, I get the following message: Unable to set up your Session Initiation Protocol account, the error we received was "Unable to Register with Server. Please check your credentials." Please go back and correct the problem.
I have tried disabling and re-enabling SIP for new credentials... Waiting... etc.
Please advise if you have a solution to this problem.
