User's Manual 19. SIP Definitions
To register or un-register the device to a Proxy/Registrar:
Click the Register button to register.
Click Un-Register button to un-register.
Instead of registering the entire device, you can register specific entities as listed below by
using the Register button located on the page in which these entities are configured:
Trunk Groups - Trunk Group table (see Configuring Trunk Groups on page 461)
Accounts - Account table (see ''Configuring Registration Accounts'' on page 363)
Click the Proxy Set Table button to Open the Proxy Sets table to configure groups of
proxy addresses. Alternatively, you can open this page from the Proxy Sets Table page
item (see ''Configuring Proxy Sets'' on page 355 for a description of this page).
19.3.1 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
Via: SIP/2.0/UDP 10.1.1.200
From: <sip: 122@10.1.1.200>;tag=1c17940

CSeq: 1 REGISTER
Contact: sip:122@10.1.1.200:

2. Upon receipt of this request, the Registrar/Proxy returns a 401 Unauthorized
response:
SIP/2.0 401 Unauthorized
