NAME
       Net::SIP::Dropper::ByField - drops SIP messages based on	fields in SIP
       header

SYNOPSIS
	   my $drop_by_field = Net::SIP::Dropper::ByField->new(
	       methods => [ 'REGISTER',	'...', '' ],
	       'From' => qr/sip(?:vicious|sscuser)/,
	       'User-Agent' => qr/^friendly-scanner$/,
	   );

	   my $dropper = Net::SIP::Dropper->new( cb => $drop_by_field );
	   my $chain = Net::SIP::ReceiveChain->new([ $dropper, ... ]);

DESCRIPTION
       With "Net::SIP::Dropper::ByField" one can drop packets based on the
       contents	of the fields in the SIP header. This can be used to drop
       specific	user agents.

CONSTRUCTOR
       new ( ARGS )
	   ARGS	is a hash with the following keys:

	   methods Optional argument to	restrict dropping to specific methods.

		   Is array reference of method	names, if one of the names is
		   empty also responses	will be	considered. If not given all
		   packets will	be checked.

	   field-name
		   Any argument	other then "methods" will be considered	a
		   field name.	The value is a callback	given to
		   "invoke_callback", like for instance	a Regexp.

METHODS
       run ( PACKET, LEG, FROM )
	   This	method is called as a callback from the	Net::SIP::Dropper
	   object.  It returns true if the packet should be dropped, e.g. if
	   at least one	of the in the constructor specified fields matches the
	   specified value.
