Call Type Bit Fields
The call type values have been selected so that individual attributes of the call type may be associated with single- or
double-bit fields within the call type byte. (The call type byte is the 8-bit value represented by the ASCII encoded, 2-digit
hexadecimal number in the CDR call type field.) Table A.3 shows these bit fields and their meaning.
