no matter which SIP provider No go.

No matter which sip provider I put in my local version of Sipsorcery, it will not register with the provider with error saying "username is rejected". YES I am very sure I am using the correct username for the provider I try.
What I notice is local sipsorcery wants to use my owner name and not the username I have with the provider. And I see this in the console when I look at what is happening.
Sip Sorcery is very frustrating to get it working on my own. I am not sure I understand the the reply to my dialplan question in another post but I guess I have to get this resolved first.
