Parsing DID digits for ANI

Some incoming trunks deliver both calling ID (ANI) and called ID in a single burst of digits. There may be a special digit such as '*' separating the two number strings. You can use the wink-start or DID protocol with these trunks.
To analyze caller ID data:

Set the numdigits parameter in the protocol's parameter structure to the total number of digits expected, including the separator character.

After an incoming call arrives, retrieve the digits from the ADI_CALL_STATUS structure with adiGetCallStatus. The entire string will be in the calledaddr field of the status structure.
