Asterisk 1.4.17 (Current branch)
01-25-2008
Asterisk is a hybrid TDM and packet voice PBX (Private Branch eXchange) and IVR platform with ACD functionality. It acts as middleware between the Internet (IAX, SIP, MGCP, Skinny, H.323), telephony channels (like Zaptel, T1, PRI, E1, FXO, FXS, VoIP, VoFR, ISDN, modems, Internet Phone Jack, etc.), and applications (like voice-mail, conferencing, directories, MP3 players, intercoms, etc.). It has many advanced features such as a codec translation API. The base distribution includes several channel backends, as well as applications. However, the beauty of Asterisk is its ability to be extended using its APIs, dynamic module loader, and AGI scripting interface. End users can even write their own applications that run on the system in C or any scripting language of their choice. License: GNU General Public License (GPL) Changes:|

Net::SIP::Dropper(3pm) User Contributed Perl Documentation Net::SIP::Dropper(3pm) 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. perl v5.14.2 2011-02-03 Net::SIP::Dropper(3pm)
