This is a good introduction to the ways that the reciprocal compensation rules can be used to benefit certain classes of traffic. CLECs are incentivized to serve "receive only" lines, i.e., lines which seldom make outgoing calls, so as to tip the compensation rules in their favor. Since the terminating company gets paid by the IEC, CLECs with a lot of conference-call or "chat room" or other customers who answer lots of calls, but make very few, can turn a profit.
Google, which is in the awkward position of having almost all "originating" traffic, must pay the higher rates which some rural ILEC/CLECs are allowed to charge for terminating calls.
