The 407 Proxy Authentication Required response indicates that the phone must first authenticate itself with the proxy server. If received by phone, the phone may repeat the INVITE request with a suitable Proxy-Authorization field. This field should contain the authentication information of the user agent for the next outbound proxy or gateway.
Solutions
- Make sure username/password are correct
