At least from the experiences I've indirectly gained, if the call
terminates on a switch with tap gear, it's similar to a SPAN port. Not
only does the recipient's phone ring, but the magic phone rings and
outputs the information from both sides of the call, while inputting
nothing. The federal folks spent big money to have the switch
manufacturers implement the software functionality, but the telcos do
have to acquire the equipment (or rights to it via contract). It was
funny watching Siemens try to tell our employee (former Siemens
employee, and experienced in CALEA) that we'd have to buy the
feature...it was less than an hour before they were calling back asking
to be able to add the feature. :)
