I'm assuming you can process the relevant files for their contents, so the problem is essentially the substitution: 

c:\@Work\Perl\monks>perl -wMstrict -le
"my %hid = (
  '1541' => '+12507741234',
  '926'  => '+12505801234',
  '927'  => '+17789701234',
  '970'  => '+16137941234',
   );
 ;;
 my ($rx_hid) =
   map  qr{ (?<! \d) (?: $_) (?! \d) }xms,
   join '|',
   map  quotemeta,
   reverse sort
   keys %hid
   ;
 print $rx_hid;
 ;;
 my $msg = join qq{\n},
   'handle_id = 1541 Sent Fri Mar 23 13:41:02 2018',
   'text = Hi Partner: Called your house & you are at a mtg.',
   'handle_id = 1541 Received Fri Mar 23 16:12:25 2018',
   'text = I got you bud',
   'handle_id = 970 Sent Fri Mar 23 16:13:56 2018',
   'text = Please pickup milk.',
   '';
 print qq{[[$msg]]};
 ;;
 $msg =~ s{ (?i) handle_id \s* = \s* ($rx_hid) }
          {id = $hid{$1}}xmsg;
 print qq{<<$msg>>};
"
(?msx-i: (?<! \d) (?: 970|927|926|1541) (?! \d) )
