RADIUS Preauthentication
When "$radius.preauth" is defined in dial plan rules, Brekeke SIP Server will send a Pre-Authentication Access-Request RADIUS packet to a RADIUS server.
If RADIUS server supports Preauthentication, RADIUS server response packet will contain return-code, credit amount, credit time, and currency. These return values can be obtained by variables below.
Syntax:
$radius.preauth
$radius.preauth( Username, Caller-ID, Called-ID, Password )
Returns:
true | false
Variables:
&preauth.h323-return-code
&preauth.h323-credit-time
&preauth.h323-credit-amount
&preauth.h323-currency
