GNU SIP Witch 0.3.11 (Default branch)
GNU SIP Witch is a pure SIP-based office telephone call server that supports generic phone system features like call forwarding, hunt groups and call distribution, call coverage and ring groups, holding, and call transfer, as well as offering SIP specific capabilities such as presence and messaging. It supports secure telephone extensions for making calls over the Internet, and intercept/decrypt-free peer-to-peer audio and video extensions. It is not a SIP proxy, a multi-protocol telephone server, or an IP-PBX, and does not try to emulate Asterisk, FreeSWITCH, or Yate. License: GNU General Public License v3 Changes:
New SWIGs for Perl, C#, and Java and a new CDR processing subsystem have been introduced. More functionality has been exposed to plugins. Image

NAME

       Net::SIP::Dropper - drops SIP messages based on callback

SYNOPSIS

	       use Net::SIP::Dropper::ByIPPort;
	       my $drop_by_ipport = Net::SIP::Dropper::ByIPPort->new(
		       database => '/path/to/database.drop',
		       methods => [ 'REGISTER', '...', '' ],
		       attempts => 10,
		       interval => 60,
	       );

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

	       my $drop_subscribe = sub {
		       my ($packet,$leg,$from) = @_;
		       # drop all subscribe requests and responses
		       return $packet->method eq 'SUBSCRIBE' ? 1:0;
	       };

	       my $dropper = Net::SIP::Dropper->new(
		       cbs => [ $drop_by_ipport, $drop_by_field, $drop_subscribe ]);

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

DESCRIPTION

       Drops messages. This means, does no further processing in the Net::SIP chain and does not send something back if the incoming message match
       the settings.

       Some useful droppers are defined in Net::SIP::Dropper::ByIpPort and Net::SIP::Dropper::ByField.

CONSTRUCTOR

       new ( ARGS )
	   ARGS is a hash with key "cb" or "cbs". "cb" is a single callback to be processed, "cbs" is an arrayref with callbacks. If one of the
	   callbacks returns true the message will be dropped. If all callbacks return false the message will be forwarded in the chain.

	   Returns a new dropper object to be used in the chain.
