5.1. SINGLE-SITE CALLS
The following diagram shows the layout of the fields in a basic CDR for a single-site call. The top row shows the field

within the record.

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).

5.3. MOBILE-TO-LAND TELEPHONE INTERCONNECT CALLS
A CDR for a mobile-to-land telephone interconnect call will have an additional field beginning at byte offset 70. This
field contains the digits dialed by the caller. A mobile-to-land call never involves multiple sites, so the PSTN Telephone
Number field is never combined with the Additional Site fields described in the preceding section.
