 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.
