Net::SIP::Authorize - enforce authorization of packets


  my $auth = Net::SIP::Authorize->new(
        dispatcher => $dispatcher,
        realm      => '',
        user2pass  => \&give_pass_for_user,
        i_am_proxy => 1,
  my $proxy = Net::SIP::StatelessProxy->new...
  my $chain = Net::SIP::ReceiveChain->new(
        # all requests for proxy need to be authorized
        [ $auth,$proxy ]


This package is used inside a Net::SIP::ReceiveChain to make sure, that requests are authorized before they get handled by the next receiver in the chain.


new ( %ARGS )

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


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


The realm for the authentication request. Defaults to 'p5-net-sip'.


Optional value for opaque parameter for the authentication request. If none is given no opaque parameter will be used.


Either hash reference with user,password mapping or callback, which gives password if called with user.


Flag if the object behind works as a proxy (e.g. Net::SIP::StatelessProxy) and sends Proxy-Authenticate or if it is an endpoint (e.g. Net::SIP::Endpoint, Net::SIP::Registrar) which sends WWW-Authenticate.


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 this object which is the case, if the packet was not authorized so that a 401 or 407 (if i_am_proxy) response was send back.

Returns FALSE if packet was authorized and should be handled be the next object in the Net::SIP::ReceiveChain. In this case it usually changes the packet to remove the local authorization information.
