In this section, you set up your own SIP settings. When you apply for an account, your SIP 
service provider will give you an Account Name or user name, SIP Registrar, Proxy, and 
Domain name. (The last three might be the same in some case). Then you can tell your folks 
your SIP Address as in Account Name@ Domain name

the destination using AccountName@Domain/Realm as identity.
