User's Manual
Description
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 functionality per specific calls, using IP Profiles
(IpProfile_SBCUserRegistrationTime). For a detailed
description of the parameter and for configuring this
functionality in the IP Profiles table, see ''Configuring
IP Profiles'' on page 418.
Note: If this functionality is configured for a specific IP
Profile, the settings of this global parameter is ignored
for calls associated with the IP Profile.
Defines the duration (in seconds) for which the user is
registered in the proxy database (after the device
forwards the REGISTER message). This value is sent
in the Expires header. When set to 0, the device
sends the Expires header's value as received from the
user to the proxy.
The valid range is 0 to 2,000,000 seconds. The
default is 0.
Defines a value (in seconds) that is used to calculate
a new value for the expiry time in the Expires header
of SIP 200 OK responses for user registration and
subscription requests from users.
The expiry time value appears in the Expires header
in REGISTER and SUBSCRIBE SIP messages.
When the device receives such a request from a user,
it forwards it to the proxy or registrar server. Upon a
successful registration or subscription, the server
sends a SIP 200 OK response. If the expiry time was
unchanged by the server, the device applies this
feature and changes the expiry time in the SIP 200
OK response before forwarding it to the user;
otherwise, the device does not change the expiry
time.
This feature is useful in scenarios where multiple
