Thanks that code worked exactly as I needed it. I just did a few small small tweaks to get it do to what I needed! 
#!/usr/bin/perl
use constant MAX_OPEN_CALLS => 100;
use strict;
use warnings;

#my $log = $ARGV[0] or die "Usage: $0 <log_file>";
#open(my $fh, '<', $log) or die "Unable to open '$log' for reading: $!
+";

my %call;

{
    local $/ = '==============================================';
    while (<>) {
        my ($type, $id, $info) = parse_rec($_);
        print "$_\n\n";
        if ($type eq 'INIT') {
            next if $info !~ /TCH/;
            $call{$id} = 1;
        }
        elsif ($type eq 'RESPONSE') {
            next if ! exists $call{$id};
            print "Call with id '$id' has a Px,Py of '$info'\n";
            print "===============================================\n";
            (my @args) = $info =~ /(.{8})(.{8}),(.{8})(.{8})/;
            #print "@args\n";
            my $cprogram = `./decrypt @args`;
            print $cprogram;
            print "===============================================\n";
            delete $call{$id};
        }        
        die "Too many unanswered calls" if keys %call > MAX_OPEN_CALLS
+;
    }
}

sub parse_rec {
    my ($rec)   = @_;
    my ($type)  = $rec =~ /CALL_(\w+)/;
    $type       = '' if ! defined $type;
    my ($id)    = $rec =~ /TRAN_ID\s+(\S+)/;
    my $info;
    if ($type eq 'INIT') {
        ($info) = $rec =~ /CHAN_TYPE\s+(\S+)/;
    }
    elsif ($type eq 'RESPONSE') {
        ($info) = $rec =~ /Px,Py\s*=\s*(\S+)/;
    }
    $info       = '' if ! defined $info;
    return ($type, $id, $info);
