NAME

       Net::SIP::Blocker - blocks SIP requests based on method name

SYNOPSIS

	 my $block = Net::SIP::Blocker->new(
		 block => { 'SUBSCRIBE' => 405, '...' => ... },
		 dispatcher => $disp,
	 );

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

DESCRIPTION

       Blocks incoming requests by method name and sends back custom error message.

CONSTRUCTOR

       new ( BLOCK,DISPATCHER )
	   Returns a new blocking object to be used in the chain.

	   BLOCK is a hash reference where the keys are the methods to be blocked and their values are the reason why the method was blocked. The
	   reason is the three digit code, optionally followed by a text.

	   DISPATCHER is a Net::SIP::Dispatcher object.

METHODS

       receive ( PACKET,LEG,FROM )
	   PACKET is the incoming packet, LEG is the Net::SIP::Leg where the packet arrived and FROM is the "ip:port" of the sender.

NAME

       Net::SIP::Registrar - Endpoint for registering SIP clients

SYNOPSIS

	 my $reg = Net::SIP::Registrar->new(
	       dispatcher => $dispatcher,
	       min_expires => 10,
	       max_expires => 60,
	       domains => [ 'example.com','example.org' ],
	 );

DESCRIPTION

       This package implements a simple SIP registrar. In the current implementation registry information are only kept in memory, e.g. they are
       not preserved over restarts.

       The implementation itself does not checking if the UAC is authorized to register the given address. This can be done with using an
       appropriate Authorize Module inside a ReceiveChain in front of the registrar.

CONSTRUCTOR

       new ( %ARGS )
	   This creates a new registar object, %ARGS can have the following keys:

	   dispatcher
		   Net::SIP::Dispatcher object manging the registar. Mandatory.

	   max_expires
		   Maximum expires time accepted. If the client requests a larger expires value it will be capped at max_expires Defaults to 300.

	   min_expires
		   Minimum expires value. If the client requests a smaller value the registrar will return a response of "423 Interval too brief".
		   Defaults to 30.

	   domains or domain
		   Either string or reference to list of strings containing the names of the domains the registrar is responsable for. If not
		   given the registrar accepts everything.

METHODS

       receive ( PACKET,LEG,FROM )
	   PACKET is the incoming packet, LEG is the Net::SIP::Leg where the packet arrived and FROM is the "ip:port" of the sender. Responses
	   will be send back to the sender through the same leg.

	   Called from the managing Net::SIP::Dispatcher object if a new packet arrives. Will return "()" and ignore the packet if it's not a
	   REGISTER request or if it is not responsable for the domain given in the "From" heeader of the REGISTER request.

	   If it is responsable for the packet it will create a response and return the code of the response. Responses are either "423 Interval
	   too brief" if the request expires time is too small, or "200 Ok" if the expires time is 0 (e.g. the client should be unregistered) or
	   greater or equal min_expires.

	   In case of a successful response it wil also update the internal registry information.

       query ( ADDR )
	   Search for ADDR (which has format "proto:user@domain") in the registry. Returns @List of all sip or sips contacts for ADDR.

       expire
	   Removes all expired entries from the internal registry.  Called whenever the registry information gets updated from sub receive.
