/** @page nua_api_overview NUA API Overview
 *
 * This page shortly overviews the NUA API: different functions, tags, and
 * where and how they affect the working of NUA engine.
 *
 * The application and the NUA engine can pass various parameters between
 * them using tagged arguments. Tagged arguments can be used like named
 * arguments in higher-lever language.
 *
 * @par NUA Agent
 *
 * The NUA agent object is created with nua_create(). The nua_create() also
 * creates the transports and binds the transport sockets used by the SIP
 * stack.
 *
 * The special tags controlling the transports are
 * - NUTAG_URL(), NUTAG_SIPS_URL(),  NUTAG_CERTIFICATE_DIR(), NUTAG_SIP_PARSER()
 *
 * See nta_agent_add_tport() for discussion about magic URIs used to
 * initialize transports.
 *
 * The agent-wide parameter can be later modified or obtained with
 * nua_set_params() and nua_get_params(), respectively.
 *
 * The #su_root_t mainloop integration uses
 * - su_root_create(), su_root_threading(),
 *   su_root_poll(), su_root_run(), su_root_break()
 *
 * @par NUA Handles
 * - nua_handle(), nua_get_hparams(), nua_set_hparams()
 * - nua_handle_home(), nua_handle_has_invite(), nua_handle_has_subscribe(),
 *   nua_handle_has_register(), nua_handle_has_active_call(),
 *   nua_handle_has_call_on_hold(), nua_handle_has_events(),
 *   nua_handle_has_registrations(), nua_handle_remote(), and
 *   nua_handle_local().
 * - Settings:
 *   See nua_set_hparams(). There are a few "sticky" headers that are used
 *   on subsequent requests if given on any handle-specific call:
 *   - @Contact, @UserAgent, @Supported, @Allow, @Organization
 *
 * @par Client Generating SIP Requests
 * - nua_register(), nua_unregister(), nua_invite(), nua_cancel(),

 *
 * @par Sending INVITE and UPDATE Requests 
 *
 * If NUTAG_SESSION_TIMER() is used with non-zero value, the value is used
 * in the @SessionExpires header included in the INVITE or UPDATE requests. 
 * The intermediate proxies or the ultimate destination can lower the
 * interval in @SessionExpires header. If the value is too low, they can
 * reject the request with the status code <i>422 Session Timer Too
 * Small</i>. In that case, @b nua increases the value of @SessionExpires
 * header and retries the request automatically.
 *
 * @par Returning a Response to the INVITE and UPDATE Requests 
 *
 * The NUTAG_SESSION_TIMER() value is also used when sending the final
 * response to the INVITE or UPDATE requests. If the NUTAG_SESSION_TIMER()
 * value is 0 or the value in the @SessionExpires header of the request is
 * lower than the value in NUTAG_SESSION_TIMER(), the value from the
 * incoming @SessionExpires header is used. However, if the value in
 * @SessionExpires is lower than the minimal acceptable session expiration
 * interval specified with the tag NUTAG_MIN_SE() the request is
 * automatically rejected with <i>422 Session Timer Too Small</i>.
 *
 * @par Refreshes
 *
 * After the initial INVITE request, the SIP session is refreshed at the
 * intervals indicated by the @SessionExpires header returned in the 2XX
 * response. The party indicated with the "refresher" parameter of the
 * @SessionExpires header sends a re-INVITE requests (or an UPDATE
 * request if NUTAG_UPDATE_REFRESH(1) parameter tag has been set).
 * 
 * @par When to Use NUTAG_SESSION_TIMER()?
 *
 * The session time extension is enabled ("timer" feature tag is included in
 * @Supported header) but not activated by default (no @SessionExpires
 * header is included in the requests or responses by default). Using
 * non-zero value with NUTAG_SESSION_TIMER() or NUTAG_SESSION_REFRESHER()
 * activates it. When the extension is activated, @nua refreshes the call
 * state by sending periodic re-INVITE or UPDATE requests unless the remote
 * end indicated that it will take care of refreshes.
 *
 * The session timer extension is mainly useful for proxies or back-to-back
 * user agents that keep call state. The call state is "soft" meaning that
 * if no call-related SIP messages are processed for certain time the state
 * will be destroyed. An ordinary user-agent can also make use of session
 * timer if it cannot get any activity feedback from RTP or other media.
 *
 * @note The session timer extension is used only if the feature
 * tag "timer" is listed in the @Supported header, set by NUTAG_SUPPORTED(),
 * SIPTAG_SUPPORTED(), or SIPTAG_SUPPORTED_STR() tags.
