Version 7.2 1303 Mediant 800B Gateway & E-SBC
User's Manual 72. Configuration Parameters Reference
Parameter Description
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.
SBC User Registration Time
configure voip > sbc settings > sbc-usr-rgstr-
time
[SBCUserRegistrationTime]
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
436.
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.
SBC Proxy Registration Time
configure voip > sbc settings > sbc-prxy-
rgstr-time
[SBCProxyRegistrationTime]
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.
configure voip > sbc settings > sbc-rand-
expire
[SBCRandomizeExpires]
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
