DESCRIPTION

CONSTRUCTOR

new ( %ARGS )

Creates new Net::SIP::Simple object.

It will return the new object for further operations, but the object itself will contain back references to itself in the form of callbacks into the eventloop and dispatcher. This means that that object will not self-destroy, but you need to call cleanup if you want it to go away.

%ARGS can be:

METHODS

cleanup

Cleans up object, removes legs it added from the dispatcher. Needs to be called if you want to destroy the object, because it will not self-destroy (see new).

error ( ERROR )

Either sets current error (used internally) or returns last error.

loop ( [ TIMEOUT, @STOPVAR ] )

Calls the event loops (key loop in constructor> loop method. TIMEOUT is the timeout for the loop in seconds. If not given it will not stop because of timeout. @STOPVAR is a list of scalar references, will stop the loop if any of these references contains TRUE. See method loop in Net::SIP::Dispatcher::Eventloop for more details.

The order of TIMEOUT or the STOPVARs is insignificant, e.g. if it finds a reference it will use it as stopvar, otherwise it's used as timeout.

add_timer ( WHEN, CALLBACK, [ REPEAT ] )

Calls same method from the Net::SIP::Dispatcher object in $self. See there for details on arguments.

rtp ( METHOD,@ARGS )

Calls the method METHOD in Net::SIP::Simple::RTP with arguments @ARGS. Currently only does this and thus works as a shortcut. In the future one might add more ways to find the right method for RTP handling (e.g. plugins or similar).

register ( %ARGS )

Registers the user agent. %ARGS can have the key registrar which has precedence over the same key in the constructor. leg specifies the leg where the register request will be send through. If not given it will pick the right leg.

If cb_final is specified it is a callback usable by invoke_callback in Net::SIP::Util which will be called, once the registration is completed (e.g. it succeeded or failed). If no cb_final is specified the method will wait, until the registration is completed and return either the expires time given by the registrar or "()" if registration failed.

All other keys, like contact, expires, resp40x, auth will be forwarded to method register in Net::SIP::Endpoint. from and auth will be used from %ARGS or if not in %ARGS from the constructor.

invite ( CTX,%ARGS )

Creates a new call and invites peer. Creates a new Net::SIP::Simple::Call object with context CTX and creates an INVITE request for this call using %ARGS. See reinvite in Net::SIP::Simple::Call for more info on %ARGS.

CTX can be address of peer or context hash containing the address.

Returns with the newly created Net::SIP::Simple::Call object, which can later be used for reINVITEs or BYE etc.

Note that in order to have any callbacks triggered by the invite working one needs to keep the returned caller object.

listen ( %ARGS )

Sets up waiting on all legs in $self for incoming calls, e.g. new INVITE requests. All other incoming packets will be dropped. If a call comes in a new Net::SIP::Simple::Call object will be created using %ARGS.

The method does not wait for the calls, its setting only the callback on the legs up. Thus it has to be followed by a call to loop.

If %ARGS contain "auth_*" keys an Authorizer will be added before the listener. See Net::SIP::Authorize for the keys, e.g. "auth_user2pass" will be forwarded as "user2pass" etc to the authorizer.

Special keys not described in Net::SIP::Simple::Call:

The returned object can be used together with other objects within "create_chain", but it should be used as the last object.

create_auth ( %ARGS )

Sets up authorization. See Net::SIP::Authorize for the meaning of %ARGS. The returned object should be used together with other objects within "create_chain".

create_registrar ( %ARGS )

Sets up a simple registrar using Net::SIP::Registrar. See there for the meaning of %ARGS.

Like with listen you need to loop after calling this method, the method itself will not wait.

Like with listen authorization can be added uses "auth_*" keys.

create_stateless_proxy ( %ARGS )

Sets up a simple proxy using Net::SIP::StatelessProxy. See there for the meaning of %ARGS.

Like with listen you need to loop after calling this method, the method itself will not wait.

Like with listen authorization can be added uses "auth_*" keys.

create_chain ( OBJECTS, %ARGS )

Sets up a chain using Net::SIP::ReceiveChain. See there for the meaning of OBJECT and %ARGS.

Like with listen you need to loop after calling this method, the method itself will not wait.
