I would like to preauthenticate calls that flow through a CUBE (Cisco Unified Border Element). It however seems to be that the 'aaa preauth' command only can be configured in AS5000s.
Accounting works great using AAA-lists. Based on this document: http://www.cisco.com/en/US/docs/ios/12_2/security/configuration/guide/scfrad.html#wp1007167 I unfortunally am not able to PRE-authenticate a call before it is established (don't see any Access-Request in debug).
Anyone any tips? I noticed a .tcl called: silent-authentication which does something with using SIP-headers to query RADIUS?
