CLI information is only included with the first RING message for a given incoming call, and appears
as follows:
RING
FM: 5552000 TO: 5551000
If the Calling Party Number information is not included in the incoming SETUP message, the RING
message appears as follows:
RING
TO: 5551000
If the Called Party Number information is not included in the incoming SETUP message, the RING
message will appear as follows:
RING
FM: 5552000
If neither the Called Party Number, nor the Calling Party Number is included in the incoming SETUP
message, the RING message will contain no additional information.
