<title>Введение</title>

<section><title>Ekiga</title>
<para><application>Ekiga</application> — это свободное приложение для IP-телефонии, VoIP (Voice over IP — голос посредством IP) и видеоконференций. Оно работает на GNU/Linux и других Unix-подобных системах (например, BSD, OpenSolaris и Mac OS X). Оно было создано Дамьяном Сандрасом (Damien Sandras) и распространяется на условиях лицензии GNU GPL.</para>

<para>
Ekiga is able to use modern Voice over IP protocols like SIP and H.323. It supports all major features defined by those protocols like <emphasis>call hold</emphasis>, <emphasis>call transfer</emphasis>, <emphasis>call forwarding</emphasis>, ... It also supports <emphasis>instant messaging</emphasis>, and <emphasis>presence</emphasis>. It also has advanced support for <emphasis>NAT traversal</emphasis>.
Ekiga supports the best <emphasis>free</emphasis> audio and video codecs, and has wideband support for a superior audio quality, together with echo cancellation.
</para>
</section>

<section><title>SIP и H.323</title>
<para>SIP (от англ. Session Initiation Protocol — протокол инициации сеанса) — это протокол, разработанный рабочей группой MMUSIC IETF. Это предлагаемый стандарт для запуска, изменения и прерывания интерактивного пользовательского сеанса, который включает в себя мультимедийные элементы — видео, голос, мгновенные сообщения, онлайн-игры, виртуальную реальность. В ноябре 2000 года SIP был принят в качестве сигнального протокола 3GPP и постоянного элемента архитектуры IMS. SIP — это один из ведущих сигнальных протоколов для VoIP.</para>

<para>H.323 был изначально создан, чтобы обеспечить механизм для передачи мультимедиа-приложений через локальные сети. Однако он быстро развился, дабы покрыть растущие запросы VoIP-сетей. Одна из сильных сторон H.323 заключается в том, что для него довольно рано стал доступен набор стандартов, определяющих не только базовую модель вызова, но также и вспомогательные службы, которые требуются для бизнес-коммуникаций. H.323 был первым VoIP-стандартом, принявшим RTP (стандарт IETF) для передачи аудио и видео через IP-сети. H.323 основан на протоколе ISDN Q.931 и приспособлен для межсетевых сценариев между IP и ISDN и между IP и QSIG. Модель вызова, подобная модели вызова ISDN, облегчает внедрение IP-телефонии в существующие сети PBX-систем, основанных на ISDN.</para>

<section><title>Тип соединения</title>
<figure>
<title/>
<graphic fileref="figures/config_d5.png"/>
</figure>

<para><application>Ekiga</application> поддерживает несколько кодеков для звука и видео. Среди них есть кодеки с отличным качеством, а есть кодеки с качеством от среднего до хорошего. Чем выше качество кодека, тем больше для него требуется пропускной способности канала. Кроме того, видеокодеки могут приспосабливать своё качество к доступной пропускной способности. Этот параметр необходим в начальной настройке <application>Ekiga</application>, чтобы приложение могло подобрать кодек, наиболее приспособленный к вашему сетевому соединению, и установить подходящие параметры качества видео. Если ваш тип соединения не указан в списке, то вам следует выбрать тот, который ближе всего к вашему, а потом вручную отрегулировать <application>Ekiga</application> в окне параметров (в разделе кодеков).</para>	

<para>
When done, continue on with the Configuration.

<section><title>Устройства звука</title>
<figure>
<title/>
<graphic fileref="figures/config_d6.png"/>
</figure>

<para>
<application>Ekiga</application> requires audio devices to play and record sound. The audio output device ouputs the incoming sound stream during a call. Please select the device that your headset or speakers are connected to. The audio input device is what your microphone is connected to. These settings might be the same as the settings for the audio player if you have only one soundcard. But please note that it is also possible to record sound via another device (e.g. internal microphone in a webcam) too.
This section also allows you to choose the ringing device. This device can be different from the audio output device. It allows you to hear the incoming call ringing sound event in your speakers, while having your headset connected for calls.

<section id="ekiga-calling-and-being-called">
<title>Как вызывать и принимать вызовы</title>

<graphic fileref="figures/call_d1.png"/>

<section><title>От компьютера к компьютеру (PC-to-PC)</title>
<para>Чтобы вы могли вызывать других пользователей, а они — вас, вам нужен SIP-адрес. Вы можете получить SIP-адрес на <ulink url="http://www.ekiga.net" type="http">http://www.ekiga.net</ulink>, как описано выше.</para>

<para>С помощью SIP-адреса вас могут вызывать другие пользователи. Аналогично, вы можете использовать SIP-адреса ваших друзей или родственников, чтобы вызывать их. Например, по адресу <emphasis>sip:dsandras@ekiga.net</emphasis> вы можете вызвать автора Ekiga.</para>

<para>Чтобы найти SIP-адреса других пользователей <application>Ekiga</application>, вы можете воспользоваться онлайновой адресной книгой <application>Ekiga</application>. Разумеется, можно вызывать и тех пользователей, которые используют какой-то другой провайдер вместо ekiga.net. На самом деле вы можете вызывать любого пользователя, использующего программу или аппаратуру SIP, и зарегистрированного у любого публичного SIP-провайдера.</para>

<para>If you know the URI address of the party that you wish to call, you may enter that URI into the sip: input box at the top of the screen and press the Connect button; eg: sip:foo@ekiga.net and pressing the Connect button would call the user at that address.</para>

<para>It is also possible to call contacts using the address book, the call history or the roster. You can add contacts you call frequently to your roster, and watch their presence information in order to know when they are available. Please refer to the appropriate section of the manual for full explanations.</para>

<tip><title>Подсказка</title><para><application>Ekiga</application> also supports H.323 and as such can call any H.323 software or hardware. Please refer to the section related to URIs to learn more about the various types of URIs that can be used to call remote H.323  and SIP users.</para></tip>
</section>

<section><title>От компьютера к настоящему телефону (PC-to-Phone)</title>

<section><title>Adding contacts to the roster</title>

<graphic fileref="figures/roster.png"/>

<para>
<application>Ekiga</application> allows you to add the contacts you dial the most in the roster. It allows to call them or start a chat conversation with your friends without having to remember their URI.
If supported by the service, <application>Ekiga</application> will display <emphasis>extended presence information</emphasis> about your friends.
Ekiga.net supports publishing presence information for its users. Software PBX systems like <ulink url="http://www.asterisk.org" type="http">Asterisk</ulink> can report if a user is on the phone or not, and <application>Ekiga</application> will display that information in its roster. 
</para>

<para>
You can thus use <application>Ekiga</application> to monitor lines on your PBX.
</para>

<para>
<application>Ekiga</application> is also able to detect other <application>Ekiga</application> users on the LAN using the Bonjour technology popularized by Apple (tm) and to display them in the roster. That supposes you have a local mDNSResponder daemon running on your computer. On Linux systems this service will usually be provided by Avahi.
</para>

<para>
To add a contact to the roster, select Chat-&gt;Add Contact, and fill in the required fields. If the service managing the URI you entered for the contact is able to publish presence status, Ekiga will automatically display it.
</para>

<para>
If you do not know the VoIP URI of a contact, you might try searching for him using the Ekiga.net online directory. To do so, select Chat -&gt; Address Book, and start searching using the 'Search Filter' feature.
</para>

<tip><title>Подсказка</title><para>You can organise your contacts in groups in the roster.</para></tip>

<section><title>Managing contacts</title>

<graphic fileref="figures/addressbook_d1.png"/>

<para>
<application>Ekiga</application> allows you to look for contacts using various sources like the <ulink url="http://www.novell.com/products/evolution" type="http">Novell Evolution</ulink> address book, an LDAP directory or the Ekiga.net contact directory. You can use the result of your search to start a chat, call the contact, or simply add him to your roster if you have frequent calls with him. To start looking for contacts, select Chat -&gt; Address Book in the menu.
To your left there will be a list dialog showing the LDAP directories as well as a list of local Address Books. The defaults are the <application>Ekiga</application> white pages, and the personal address book from <ulink url="http://www.novell.com/products/evolution" type="http">Novell Evolution</ulink>. Support for more contact sources is possible. 
</para>

<para>
<application>Ekiga</application> is able to browse any LDAP directory and use any attribute as the calling URI. For example, you could have an LDAP directory in your company, with a specific attribute containing the local extensions of all your colleagues. <application>Ekiga</application> is able to use such an LDAP directory. Simply select in Address Book -&gt; Add an LDAP Address Book, and fill in the required details. You can then right-click on the contact and call him using the call attribute as VoIP URI.
</para>

<para>
The LDAP Address Book supports a range of settings to allow it to work with any LDAPv3 directory. It allows you to choose the attribute to use for displaying a contact's name in the address book as well as a list of attributes for callng info. E.g., if the directory uses the LDAP inetOrgPerson schema you can configure the Address Book to retrieve the homePhone, mobile, and pager attributes make those values available for calling or messaging. You can also customize a Filter Template for the default LDAP search filter, and override the default filter at any time if you need to perform a more specialized search. The browser also supports all security options for LDAP including ldaps:// (LDAP over SSL), StartTLS, and SASL authentication. 
</para>

<para>
To refresh the list of users for a specific address book, simply click the Find button. It will search for all users in that address book. You can contact people by double clicking on their highlighted field. You can also message them by right-clicking or by choosing the appropriate action in the Action menu of the window.
</para>

<para>
In certain cases you will want to search specifically for a person name, or his or her call URI in the <application>Ekiga</application> white pages. The address book window allows you to apply filters when searching for contacts. When searching an LDAP directory, entering a simple name in the Search Filter field will perform an LDAP Substring search using the configured Filter Template. If you need to perform a more specialized search you can enter a complete LDAP Filter string, and it will be used instead of the configured Filter Template.
</para>

<tip><title>Подсказка</title><para>The <application>Ekiga</application> white pages will allow you to look for users in your region. It returns a limited number of results corresponding to your search. You can then add them to your personal roster to call them later.</para></tip>
</section>

<section><title>Editing contacts</title>

<graphic fileref="figures/addressbook_d2.png"/>

<para>
Local address books provided by Novell Evolution allow you to add new contacts, or to edit existing contacts. Each different address book allows a different set of features depending on what makes sense for the address book in question. To discover what features are possible, simply select the address book and consult the Action menu. 
</para>

<para>
To add a contact to one of your local address books, simply select the address book you wish to add the contact to and select Action -&gt; New Contact. The option of adding a New Contact will appear and you may now enter his name and VoIP URI as well as other settings. After complete select 'OK' and now your contact has been added.

<section id="ekiga-video-bandwidth">
<title>Управление полосой пропускания видео</title>

<para><application>Ekiga</application> uses a best-effort algorithm to maintain a low bandwidth when transmitting video. You can adjust the video quality settings depending on whether you prefer to have a good frame rate, or a good picture quality. It will permit <application>Ekiga</application> to dynamically adjust the video bandwidth and the number of transmitted images per second during a call while trying to respect the requested video bandwidth.</para>

<para>Notice that the algorithm is a best-effort algorithm, which means that if your video bandwidth settings are too low, it can be impossible to respect them. However, if the video bandwidth permits to transmit with a better quality, or faster than the requested values, then <application>Ekiga</application> will dynamically increase them so that the quality and the framerate are always the best possible.</para>

<para>Choosing a higher framerate and a lower quality will have the same result in terms of video bandwidth as choosing a higher quality with a lower framerate. The choice depends on if you prefer using your bandwidth to transmit more lower quality images or fewer high quality images.</para>

<para><application>Ekiga</application> can connect to PBX systems supporting the SIP protocol. In that case, it is able to indicate if the line associated with a user is in use or not. Please refer to the documentation of your PBX to enable that feature.</para>

<para>To enable that feature on <application>Ekiga</application>, simply add the contact with his URI in the roster. If the server supports publishing presence information, <application>Ekiga</application> will automatically publish your own presence information and display the presence of contacts in your roster.</para>

<graphic fileref="figures/audio_codecs.png"/>

<para>
The <application>Ekiga</application> audio codecs table in the preferences permits you to change the codec order as well as disabling the codecs you don't want to use. Each codec has strong and weak points. For example, G.711 will give the best voice quality but will use the most bandwidth while SPEEX will give an average voice quality but requiring a very low bandwidth usage. Notice that there are two versions of SPEEX; one of them is SPEEX WideBand, which has a 16 kHz clock rate.</para>
</section>

<section><title>Video Codecs</title>

<graphic fileref="figures/video_codecs.png"/>

<para>
The <application>Ekiga</application> video codecs table in the preferences permits you to change the codec order as well as disabling the codecs you don't want to use. <application>Ekiga</application> supports codecs like H.261, H.263+, H.264, MPEG-4 or Theora.</para>
</section>


<section><title>Изменение порядка кодеков</title>
<para>
When you reorder the codecs, you are reordering the local capabilities table, ie the codecs you will use for sending. You will always transmit audio and video using the first codec in the corresponding table that is in common with the remote user. The remote user will transmit audio and video using the first codec in his table that is common with you.</para>
</section>

<section><title>Принудительное использование определённого кодека</title>
<para>
You can force the use of a specific codec by disabling all other codecs, but it will result in failed calls if the remote user doesn't support that specific codec. The best approach is to put your preferred codecs at the top of the list so that you always transmit with them if the remote user allows it and to disable the codecs that you don't want to use for transmission and reception.</para>
</section>

<section><title>Настройка буфера</title>
<para>
You can adjust the delay to wait before playing the sound buffers that you have received using the jitter buffer adjustment. If there is too much packet loss, the delay required to have received all packets could be so important that it will exceed the jitter buffer. In such a case, the sound you are receiving will be of bad quality. A solution to that problem would be to increase the maximum limit of the jitter buffer to a few seconds, resulting in a big delay but in an improved voice quality. Notice that the jitter buffer will readapt itself to the lowest delay allowing for optimum transmission, and that a bad voice quality in reception is not due to a too low jitter buffer value, but to bad internet connection quality.

<section id="ekiga-defining-ports">
<title>Смена портов</title>

<section><title>Порты прослушивания</title>
<para>
The main port used to listen for incoming connections in <application>Ekiga</application> for SIP is port 5060 (UDP), while 1720 (TCP) is used by H.323. To change those ports you need to load "gconf-editor". Open gconf-editor, select apps from the left hand side menu and then select <application>Ekiga</application>, Protocols. Then select "sip" or "h323", it should give you a list in the corresponding window to your right. Select listen_port and change it to your desired value. You can also change the UDP/RTP port ranges.
</para>
</section>

<section><title>Объяснение диапазонов портов</title>

<para>1. The "listen_port" value is the port <application>Ekiga</application> will use to listen for incoming connections. It is different for SIP and H.323.</para>

<para>2. The "udp_port_range" value is the range of UDP ports that <application>Ekiga</application> will use for SIP signalling or when registering to H.323 gatekeepers. It is also used for RTP (audio and video communication channels).</para>

<para>3. The "tcp_port_range" value is the range of TCP ports beside the listen_port that <application>Ekiga</application> will use for the H.245 channel with the H.323 protocol. That port range is not used by SIP. It is also not used when H.245 Tunneling is enabled, which is generally the case, except when calling old H.323 implementations like Netmeeting.</para>

<para><emphasis>Туннелирование H.245</emphasis></para>

<para>Туннелирование H.245 — это инкапсуляция сообщений H.245 внутри сообщений H.225/Q.931. Если у вас есть сетевой экран, то при включённом туннелировании H.245 вам потребуется открыть для входящих соединений на один TCP-порт меньше.</para>

<para>This enables H.245 early in the setup and permits achieving faster call initiation.</para>

<para><emphasis>Быстрый старт</emphasis></para>

<para>Быстрый старт — это новый способ установки вызовов, который пропускает некоторые обычные этапы, чтобы ускорить процесс. Помимо повышения скорости, быстрый старт позволяет медиа-каналам перейти в режим готовности до отправки сообщения CONNECT, что требуется для некоторых процедур тарификации. Этот режим появился в H.323 версии 2.</para>
