SIP Message Authentication Example
The device supports basic and digest (MD5) authentication types, according to SIP RFC 3261. 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 re-send
the INVITE with a Proxy-Authorization header containing the credentials.
User agents, Redirect or Registrar servers typically use the SIP 401 Unauthorized response to
challenge authentication containing a WWW-Authenticate header, and expect the re-INVITE to
contain an Authorization header.
The following example shows the Digest Authentication procedure, including computation of user
agent credentials:
1.
The REGISTER request is sent to a Registrar/Proxy server for registration:
REGISTER sip:10.2.2.222 SIP/2.0

CSeq: 1 REGISTER

2.
Upon receipt of this request, the Registrar/Proxy returns a 401 Unauthorized response:
SIP/2.0 401 Unauthorized
Via: SIP/2.0/UDP 10.2.1.200
From: <sip:[email protected] >;tag=1c17940
