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.

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.
