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.
