CINFO cell limitation over DPNSS
The CINFO cell is used to pass information from the switch up to the
application to allow the application to route calls appropriately. However,
when the call is coming in over DPNSS, the CINFO cell can only process
three types of information: the DNIS, ANI, and CLC. This is indicated by 0,
1, and 3 respectively in the CINFO cell. Attempting to retrieve other
information forces the application to take the NO_DATA branch from the
cell.
