Classic misunderstanding/misconfiguration between ANI and CPN.
Toll-free numbers get 'ANI' from the carrier, which is a billing
number, not necessarily a calling party number. Many carriers have
been substituting CPN in place of ANI when they deliver ANI streams
for 8xx calls, but it varies. There is also a dependency on how the
cell provider is configured -- in this day and age it would be possible
for them to send the cellular number as both ANI and CPN, if they are
so configured and their interconnect agreements with other carriers
allow.
