Modifiers for InCgPN—
the selected caller (CgPN) number modifier for the incoming connection in
relation to the
Calling-Station-Id, xpgk-src-number-in
fields of RADIUS-Authorization and RADIUS-
Accounting messages.
Modifiers for OutCdPN—
the selected callee (CdPN) number modifier for the outgoing connection
in relation to the
xpgk-src-number-out
field of RADIUS-Authorization and RADIUS-Accounting
messages
.
Modifiers for OutCgPN modifiers—
the selected caller (CgPN) number modifier for the outgoing
connection in relation to the
xpgk-dst-number-out
field of RADIUS-Authorization and RADIUS-
Accounting messages.
RADIUS-Authorization settings
Authentication/authorisation requests can be transmitted during various call phases:
on ingress seize;
on end-of-dial (full number dial reception).
In case of a server fault (no response from the server), the outgoing communications can be restricted:
no restrictions—allows all calls;
local and zone networks only—allows calls to special services, local and zone network;
local network only—allows calls to special services and local network;
emergency only—allows calls to special services only;
deny all—denies all calls.
This restriction governs call routing by a prefix controlling the corresponding call type (local, long-distance,
etc.).
USER-NAME field—the selected value of the User-Name attribute in the corresponding Access
Request authorisation packet (RADIUS-Authorization):
–
CgPN—uses the calling party phone number as the value;
–
IP or E1-stream—uses the calling party IP address or incoming connection stream number
as the value;
–
Trunk name—uses incoming connection trunk name as the value.
USER-PASSWORD field—specifies the value of the User-Password attribute in the corresponding
RADIUS-Authorization packet.
Session time—
limits the maximum call duration
:
–
Ignore—
the maximum call duration is not limited
;
–
Consider Session-Time—
uses the
Session-Timeout(27)
value to limit the maximum call
duration
;
–
Consider Cisco h323-credit-time—
uses the
Cisco VSA (9) h323-credit-time(102) value
to
limit the maximum call duration
;
–
Session-Time priority—
if the server response has both parameters specified
(session-time
and
Cisco h323-credit-time), session-time
is used and
Cisco h323-credit-time
is ignored
.
–
Cisco h323-credit-time priority—
if the server response has both parameters specified
(session-time
and
Cisco h323-credit-time), Cisco h323-credit-time
is used and
session-time
is ignored
.
The SMG gateway can use the
Session-Timeout
or
Cisco VSA h323-credit-time
values from the
Access-Accept packet in order to limit the maximum duration of an authorised call.
Enable emergency call on receiving Reject
—
when Access-Reject is received from the server, calls
to the special services node are allowed.
