5.4. CALCULATING THE NUMBER OF BYTES IN A CDR
Note that the final linefeed character which terminates the record is not shown in these diagrams. The actual number of bytes in a CDR is calculated by adding 2 to the offset of the final byte. For example, a group call involving 4 sites contains 3 additional site fields, beginning at offset 70 and ending at offset 93 (from the formulae above). The actual length of the record, including the linefeed character, is thus 95 bytes.
