Description
Defines the authentication and integrity
level of quality of protection (QoP) for digest
authentication offered to the client. When
the device challenges a SIP request (e.g.,
INVITE), it sends a SIP 401 response with
the Proxy-Authenticate header or WWW-
Authenticate header containing the 'qop'
parameter. The QoP offered in the 401
response can be 'auth', 'auth-int', both 'auth'
and 'auth-int', or the 'qop' parameter can be
omitted from the 401 response. In response
to the 401, the client needs to send the
device another INVITE with the MD5 hash
of the INVITE message and indicate the
selected auth type.
■ [0] 0 = The device sends 'qop=auth' in
the SIP response, requesting
authentication (i.e., validates user by
checking user name and password).
This option does not authenticate the
message body (i.e., SDP).
■ [1] 1 = The device sends 'qop=auth-int'
in the SIP response, indicating required
authentication and authentication with
integrity (e.g., checksum). This option
restricts the client to authenticating the
entire SIP message, including the body,
if present.
■ [2] 2 = (Default) The device sends
'qop=auth, auth-int' in the SIP response,
indicating either authentication or
integrity. This enables the client to
choose 'auth' or 'auth-int'. If the client
chooses 'auth-int', then the body is
included in the authentication. If the
client chooses 'auth', then the body is
not authenticated.
■ [3] 3 = No 'qop' parameter is offered in
the SIP 401 challenge message.
Global parameter that defines the duration
(in seconds) of the periodic registrations
that occur between the user and the device
(the device responds with this value to the
user). You can also configure this feature
per specific calls, using IP Profiles
(IpProfile_SBCUserRegistrationTime). For
a detailed description of the parameter and
for configuring this feature in the IP Profiles
table, see Configuring IP Profiles.
