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 );

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.
