What is the difference between SIP response code 407 and HTTP response code 407 (Proxy Authentication Required)?

  • If you feel that you have to slap non-programming-related on your question, maybe you should think of a better way to ask your question... – Shog9 Jun 24 '09 at 16:06

According to this PDF, you get (or send) a 407 with SIP when you cannot authenticate the originator because no credentials are provided.

An HTTP 407 is, as you said, given when proxy authentication is required - essentially, they're the same.

  • SIP's 407 says "you need to authenticate to use this communication channel" (as opposed to SIP's 401 - "you need to authenticate to contact this user agent") so yes, SIP's 407 and HTTP's 407 are identical in function. – Frank Shearar May 27 '10 at 08:53
