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.

NAME

       Net::SIP::ReceiveChain - handle incoming packet by multiple receivers

SYNOPSIS

	 # create proxy which works as a registrar too, but
	 # all register requests should be authorized

	 my $registrar = Net::SIP::Registrar->new...
	 my $auth = Net::SIP::Authorize->new ....
	 my $reg_chain = Net::SIP::ReceiveChain->new(
	       [ $auth,$registrar ],
	       methods => [ 'REGISTER' ],
	 );

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

DESCRIPTION

       This package is used to handle incoming packets by multiple receivers, e.g. make sure that requests for Net::SIP::Registrar will be
       authorized by Net::SIP::Authorize.

       Objects in the chain might be Net::SIP::Registrar, Net::SIP::StatelessProxy, Net::SIP::Authorize, Net::SIP::ReceiveChain itself and every
       other object which handles "receive" like described below.

CONSTRUCTOR

       new ( OBJECTS, %ARGS )
	   This creates a new registar object, OBJECTS is a reference to an array of objects implementing the "receive" method.

	   %ARGS can have the following keys:

	   filter  A callback which gets called during "receive" with all arguments of the method. If it returns TRUE the packet will be handled
		   by the chain, otherwise not.

	   methods If filter is not given but methods is it will set filter to a callback which accepts only the methods specified in the array
		   reference given to methods.

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.

	   Returns TRUE if the packet was fully handled by one of the objects in the chain, else FALSE:

	   o	   If a filter was given checks the packet against the filter and returns FALSE if the filter does return FALSE.

	   o	   Otherwise it will call "receive" on all objects in the chain until one of these returns TRUE. In this case it will return TRUE.

	   o	   If no object in the chain handled the packet it will return FALSE.
