SIP/2.0 401 Unauthorized

So authentication is not good...
You should talk to your provider and find out how you should authenticate.

[ranjithvkumar]

Yes its problem with the SIP service provider, they didn't enabled SIP for my account so i was getting the "SIP/2.0 401 Unauthorized" error.

Now the problem is solved and thinks are working fine.

Thanks tot3nkopf.
