"wow" is all i can say to this..

let me enlighten you on the basics of Perl

if you understood  perl you would see that this line shows your complete
lack of ability as $text could be declared as its used in the loop

to demonstrate such amazing techniques such as declaring variables properly
i will demonstrate this code

die ($!) unless open  my $file,'<',"/etc/passwd";
my @b = <$file>;

while(my $a = shift @b){
        print $a;
}

notice the "my $a" ... please take a few minutes to reflect on  this code as
your fragile phd minds can only handle so much but soon it will come to you

"The sense of the match can be reversed by using !~ operator:

    print <http://perldoc.perl.org/functions/print.html> "It doesn't
match\n" if "Hello World" !~ /World/;"

Understanding that you do not know how to code i will make it easier for
you:

 "while ($text !~ /^SIP\/2.0 100(.\r\n)*/ ){"
