7.12.2 SIP Authentication Example
The device supports basic and digest (MD5) authentication types, according to SIP RFC
3261 standard. A proxy server might require authentication before forwarding an INVITE
message. A Registrar/Proxy server may also require authentication for client registration. A
proxy replies to an unauthenticated INVITE with a 407 Proxy Authorization Required
response, containing a Proxy-Authenticate header with the form of the challenge. After
sending an ACK for the 407, the user agent can then resend the INVITE with a Proxy-
Authorization header containing the credentials.
User agent, redirect or registrar servers typically use 401 Unauthorized response to
challenge authentication containing a WWW-Authenticate header, and expect the re-
INVITE to contain an Authorization header.
The following example describes the Digest Authentication procedure, including
computation of user agent credentials:
1.
The REGISTER request is sent to Registrar/Proxy server for registration, as follows:
