1) why are you using 2.0.2? You could be using 3.0.5 which is much better
2) thanks for posting your specs, however you left out your asterisk version (it's likely to be "standard", but this particular question could have differences based on asterisk version and remember that this post will be here for many years in the future, so always post your asterisk version available by entering "asterisk -R" at the command line).
3)
integrate the phone to the vicidial account
what is actually happening is that you must first "register" your SIP phone to your asterisk server.
Vicidial will configure the asterisk server to allow this (Admin->Phones).
You must also configure asterisk to call out through your VOIP provider. Vicidial will configure this also (Admin->Carriers).
How it is done is rather complex which is why there is a tutorial for it in the manual, where did you "have a problem"?
Is your "phone" registering to your vicidial server?
Is your vicidial server trunk "registering" to your provider?
