thank you. I am definitely going through them(tutorials)
Here is my working code to date,

I plan to add one sub to do more with the data but this is great
that it's working this far. But I am gonna go back to tutorials to read more on everything that I am lacking to
program .. but you guys are great!!

#!/usr/bin/perl -w

use strict;
use diagnostics;

my $ncb = $/;
my $cbn = $";

$/ = "\n\n";
$" = "\n";

my $yahoo = shift @ARGV;

open FH, "$yahoo" or die "can't open $!";

my $callid;
my $sipm;
my %data1 = ();
my $count = 0;
my $size = 15;

while (<FH>) {
        chomp;
        if (m/###/) {
                next;
        }
       unless (m{(?:^\bSIP\/2\.0 \b)?(\d\d\d|^[A-Z]{3,6} ).*(Call-ID: 
+[\S]{25,80})[^ ]+: .*}s) {
               $count++;
                next;
       }
       ($sipm,$callid) = ($1,$2);
        push (@{$data1{$callid}}, $sipm);
}
close FH;

$/ = $ncb;
$" = $cbn;

print "There were $count which could not detect\n";


HANA: foreach $callid (sort keys %data1) {
         my @fields = @{$data1{$callid}};
         my @fields1 = @fields;
         @fields1 = map { s/\s//g; $_ } @fields1;
         if ("$size" > ($#fields1 + 1)) {
               next HANA;
         } else {
             print @fields1;
         }
      print "\n";
