Net::SIP::Registrar - Endpoint for registering SIP clients
my $reg = Net::SIP::Registrar->new( dispatcher => $dispatcher, min_expires => 10, max_expires => 60, domains => [ 'example.com','example.org' ], );
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.
This creates a new registar object, %ARGS can have the following keys:
Net::SIP::Dispatcher object manging the registar. Mandatory.
Maximum expires time accepted. If the client requests a larger expires value it will be capped at max_expires Defaults to 300.
Minimum expires value. If the client requests a smaller value the registrar will return a response of
423 Interval too brief. Defaults to 30.
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.
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.
Search for ADDR (which has format
proto:user@domain) in the registry. Returns @List of all sip or sips contacts for ADDR.
Removes all expired entries from the internal registry. Called whenever the registry information gets updated from sub receive.
