5.2. MULTIPLE-SITE CALLS
A CDR may have 0 to n additional fields added beginning at byte offset 70, where n = No. of Sites - 1. The format of
the additional fields is identical to the Site of Origin field (field 13) and is shown in the diagram below. The offset, x, of the
first byte in each additional field is calculated as x = 62 + (8n).
