Indeed they do, it's part of the billing information they use to
compute your bill. Each billing record for an outgoing call records
the calling number (so they know who to bill- duh), the number called,
the cell the call originated on, start time and duration. The
originating cell info & the called number are used by the billing
process to determine if the call is billed as local or long distance.

Same thing only different for incoming calls.
