right... plus the management (for cisco) is via snmp(v3), from
(mostly) windows servers as the mediation devices (sad)...  and the
traffic is simply tunneled from device -> mediation -> lea .... not
necessarily IPSEC'd from mediation -> LEA, and udp-encapped from
device -> mediation server.

yea, good times... that's really just re-use of the normal LEA hooks
in all telco phone switch gear though... not 'calea features' in
particular.
