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.
