By selecting access points specific to the various components of
call-content of a call, a monitoring agency is ensured of obtaining the
call-content of each participant in telephone call irrespective of call
transfers and network reconfiguration. Devices in the telecommunications
system such as network devices can provide appropriate access. Examples
of suitable network devices may include gateway, an access gateways,
trunk gateways, portals, ATM switches, routers, and border elements.
