Issue with outbound and inbound calls

I cannot make calls and cannot receiive calls using asterisk with vonage

this is what i get

=========
– Called vonage/
– Got SIP response 404 “Not Found” back from 216.115.25.198
– SIP/vonage-54be is circuit-busy

Have you tried using xTen’s softphone? Perhaps you have the incorrect settings from vonage.
