# FAQ
## General
### How do I install another.im?
another.im is entirely open source and licensed under GPLv3. So if you are a
software developer you can check out the sources from GitHub and use Gradle to
build your apk file.
### How do I create an account?
XMPP, like email, is a federated protocol, which means that there is not one company you can create an *official XMPP account* with. Instead there are hundreds, or even thousands, of providers out there. One of those providers is [another.im](https://another.im). If you dont like to use *another.im* use a web search engine of your choice to find another provider. Or maybe your university has one. Or you can run your own. Or ask a friend to run one. Once you've found one, you can use another.im to create an account. Just select *register new account* on server within the create account dialog.
#### Domain hosting
Using your own domain not only gives you a more recognizable Jabber ID, it also gives you the flexibility to migrate your account between different XMPP providers. This is a good compromise between the responsibilities of having to operate your own server and the downsides of being dependent on a single provider.
#### Running your own
If you already have a server somewhere and are willing and able to put the necessary work in you can run your own XMPP server.
As of 2023 XMPP has reached a level of maturity where all major XMPP servers ([ejabberd](https://ejabberd.im), [Prosody](https://prosody.im), [Openfire](https://www.igniterealtime.org/projects/openfire/), [Tigase](https://tigase.net/xmpp-server/)) should work well with another.im.
Interoperability with Prosody and ejabberd is tested fairly regularly just because of their market share but we occasionally test with other servers too and fix issues as soon as we are being made aware of them.
### Where can I set up a custom hostname / port
another.im will automatically look up the SRV records for your domain name
which can point to any hostname port combination. If your server doesnt provide
those please contact your admin and have them read
[this](http://prosody.im/doc/dns#srv_records). If your server operator is unwilling
to fix this you can enable advanced server settings in the expert settings of
another.im.
### I get 'Incompatible Server'
As regular user you should be picking a different server. The server you selected
is probably insecure and/or very old.
If you are a server administrator you should make sure that your server provides
either STARTTLS or [XEP-0368: SRV records for XMPP over TLS](https://xmpp.org/extensions/xep-0368.html).
On rare occasions this error message might also be caused by a server not providing
a login (SASL) mechanism that another.im is able to handle. another.im supports
SCRAM-SHA1, PLAIN, EXTERNAL (client certs) and DIGEST-MD5.
### I get 'Bind failure'. What does that mean?
Some Bind failures are transient and resolve themselves after a reconnect.
When trying to connect to OpenFire the bind failure can be a permanent problem when the domain part of the Jabber ID entered in another.im doesnt match the domain the OpenFire server feels responsible for. For example OpenFire is configured to use the domain `a.tld` but the Jabber ID entered is `user@b.tld` where `b.tld` also points to the same host. During bind OpenFire tries to reassign the Jabber to `user@a.tld`. another.im doesnt like that.
This can be fixed by creating a new account in another.im that uses the Jabber ID `user@a.tld`.
Note: This is kind of a weird quirk in OpenFire. Most other servers would just throw a 'Server not responsible for domain' error instead of attempting to reassign the Jabber ID.
Maybe you attempted to use the Jabber ID `test@b.tld` because `a.tld` doesnt point to the correct host. In that case you might have to enable the extended connection settings in the expert settings of another.im and set a host name.
### I get 'Stream opening error'. What does that mean?
In most cases this error is caused by ejabberd advertising support for TLSv1.3 but not properly supporting it. This can happen if the OpenSSL version on the server already supports TLSv1.3 but the fast\_tls wrapper library used by ejabberd not (properly) support it. Upgrading fast\_tls and ejabberd or - theoretically - downgrading OpenSSL should fix the issue. A work around is to explicitly disable TLSv1.3 support in the ejabberd configuration. More information can be found on [this issue on the ejabberd issue tracker](https://github.com/processone/ejabberd/issues/2614).
**The battery consumption and the entire behavior of another.im will remain the same (as good or as bad as it was before). Why is Google doing this to you? We have no idea.**
#### Android <= 7.1 or another.im from F-Droid (all Android versions)
The foreground notification is still controlled over the expert settings within another.im as it always has been. Whether or not you need to enable it depends on how aggressive the non-standard 'power saving' features are that your phone vendor has built into the operating system.
#### Android 8.x
Long press the permanent notification and disable that particular type of notification by moving the slider to the left. This will make the notification disappear but create another notification (this time created by the operating system itself.) that will complain about another.im (and other apps) using battery. Starting with Android 8.1 you can disable that notification again with the same method described above.
#### Android 9.0+
Long press the permanent notification and press the info `(i)` button to get into the App info screen. In that screen touch the 'Notification' entry. In the next screen remove the checkbox for the 'Foreground service' entry.
### another.im doesnt work for me. Where can I get help?
You can join our conference room on [`xmppclient-dev@conference.another.im`](xmpp:xmppclient-dev@conference.another.im).
A lot of people in there are able to answer basic questions about the usage of
another.im or can provide you with tips on running your own XMPP server. If
you found a bug or your app crashes please read the Developer / Report Bugs
section of this document.
### How does the address book integration work?
The address book integration was designed to protect your privacy. another.im
neither uploads contacts from your address book to your server nor fills your
address book with unnecessary contacts from your online roster. If you manually
add a Jabber ID to your phones address book another.im will use the name and
the profile picture of this contact. To make the process of adding Jabber IDs to
your address book easier you can click on the profile picture in the contact
details within another.im. This will start an "add to address book" intent
with the JID as the payload. This doesn't require another.im to have write
permissions on your address book but also doesn't require you to copy/paste a
JID from one app to another.
### I get 'delivery failed' on my messages
If you get delivery failed on images it's probably because the recipient lost
network connectivity during reception. In that case you can try it again at a
later time.
For text messages the answer to your question is a little bit more complex.
When you see 'delivery failed' on text messages, it is always something that is
being reported by the server. The most common reason for this is that the
recipient failed to resume a connection. When a client loses connectivity for a
short time the client usually has a five minute window to pick up that
connection again. When the client fails to do so because the network
connectivity is out for longer than that all messages sent to that client will
be returned to the sender resulting in a delivery failed.
Instead of returning a message to the sender both ejabberd and prosody have the
ability to store messages in offline storage when the disconnecting client is
the only client. In prosody this is available via an extra module called
```mod_smacks_offline```. In ejabberd this is available via some configuration
settings.
Other less common reasons are that the message you sent didn't meet some
criteria enforced by the server (too large, too many). Another reason could be
that the recipient is offline and the server doesn't provide offline storage.
Usually you are able to distinguish between these two groups in the fact that
the first one happens always after some time and the second one happens almost
instantly.
### Where can I see the status of my contacts? How can I set a status or priority?
Statuses are a horrible metric. Setting them manually to a proper value rarely
works because users are either lazy or just forget about them. Setting them
automatically does not provide quality results either. Keyboard or mouse
activity as indicator for example fails when the user is just looking at
something (reading an article, watching a movie). Furthermore automatic setting
of status always implies an impact on your privacy (are you sure you want
everybody in your contact list to know that you have been using your computer at
4am‽).
In the past status has been used to judge the likelihood of whether or not your
messages are being read. This is no longer necessary. With Chat Markers
(XEP-0333, supported by Conversations since 0.4) we have the ability to **know**
whether or not your messages are being read. Similar things can be said for
priorities. In the past priorities have been used (by servers, not by clients!)
to route your messages to one specific client. With carbon messages (XEP-0280,
supported by Conversations since 0.1) this is no longer necessary. Using
priorities to route OTR messages isn't practical either because they are not
changeable on the fly. Metrics like last active client (the client which sent
the last message) are much better.
Unfortunately these modern replacements for legacy XMPP features are not widely
adopted. However another.im should be an instant messenger for the future and
instead of making another.im compatible with the past we should work on
implementing new, improved technologies and getting them into other XMPP clients
as well.
Making these status and priority optional isn't a solution either because
another.im is trying to get rid of old behaviours and set an example for
other clients.
### How do I backup / move another.im to a new device?
Use the Backup button in the Settings.
### another.im is missing a certain feature
Please report it to our XMPP conference [`xmppclient-dev@conference.another.im`](xmpp:xmppclient-dev@conference.another.im).
## Security
### Why are there two end-to-end encryption methods and which one should I choose?
* OMEMO works even when a contact is offline, and works with multiple devices. It also allows asynchronous file-transfer when the server has [HTTP File Upload](http://xmpp.org/extensions/xep-0363.html). However, OMEMO not widely support and is currently implemented only [by a handful of clients](https://omemo.top).
* OpenPGP (XEP-0027) is a very old encryption method that has some advantages over OMEMO but should only be used by people who know what they are doing.
### How do I use OpenPGP
Before you continue reading you should note that the OpenPGP support in
another.im is experimental. This is not because it will make the app unstable
but because the fundamental concepts of PGP aren't ready for widespread use.
The way PGP works is that you trust Key IDs instead of JID's or email addresses.
So in theory your contact list should consist of Public-Key-IDs instead of
JID's. But of course no email or XMPP client out there implements these
concepts. Plus PGP in the context of instant messaging has a couple of
downsides: It is vulnerable to replay attacks and it is rather verbose.
To use OpenPGP you have to install the open source app
[OpenKeychain](http://www.openkeychain.org) and then long press on the account in
manage accounts and choose renew PGP announcement from the contextual menu.
### OMEMO is grayed out. What do I do?
OMEMO is only available in 1:1 chats and private (members-only, non-anonymous) group chats. Encrypting public group chats makes little to no sense since anyone (including a hypothetical attacker) can join and a user couldnt possibily verify all participants anyway. Furthermore for a lot of public group chat it is desirable to give new comers access to the full history.
### OMEMO doesnt work. I get a 'Something went wrong' message in the 'Trust OMEMO Fingerprints' screen.
OMEMO has two requirements: Your server and the server of your contact need to support PEP. Both of you can verify that individually by opening your account details and selecting ```Server info``` from the menu. The appearing table should list PEP as available. The second requirement is that the initial sender needs to have access to the published key material. This can either be achieved by having mutual presence subscription (you can verify that by opening the contact details and see if both check boxes *Send presence updates* and *Receive presence updates* are checked) or by using a server that makes the public key material accessible to anyone. In the [Compliance Tester](https://compliance.conversations.im) this is indicated by the 'OMEMO' feature. Since it is very common that the first messages are exchanged *before* adding each other to the contact list it is desirable to use servers that have 'OMEMO support'.
### How does the encryption for group chats work?
#### OMEMO
OMEMO encryption works only in private (members only) conferences that are non-anonymous. Non-anonymous (being able to discover the real JID of other participants) is a technical requirement to discover the key material. Members only is a sort of arbitrary requirement imposed by another.im. (see 'OMEMO is grayed out')
The server of all participants need to pass the OMEMO [Compliance Test](https://conversations.im/compliance/).
In other words they either need to run ejabberd 18.01+ or Prosody 0.11+.
(Alternatively it would also work if all participants had each other in their contact list; But that rarely is the case in larger group chats.)
The owner of a conference can make a public conference private by going into the conference
details and hit the settings button (the one with the gears) and select both *private* and
*members only*.
#### OpenPGP
Every participant has to announce their OpenPGP key (see answer above).
If you would like to send encrypted messages to a conference you have to make
sure that you have every participant's public key in your OpenKeychain.
Right now there is no check in another.im to ensure that.
You have to take care of that yourself. Go to the conference details and
touch every key id (The hexadecimal number below a contact). This will send you
to OpenKeychain which will assist you on adding the key. This works best in
very small conferences with contacts you are already using OpenPGP with. This
feature is regarded experimental. another.im is the only client that uses
XEP-0027 with conferences. (The XEP neither specifically allows nor disallows
this.)
### What is Blind Trust Before Verification / why are messages marked with a red lock?
Read more about the concept on https://gultsch.de/trust.html
### I found a bug
Please report it to our XMPP conference [`xmppclient-dev@conference.narayana.im`](xmpp:xmppclient-dev@conference.narayana.im).

we just offer you a standardized xmpp-client with predicted features which work equally on all platforms.\
in our clients we have realized pure XMPP and you won't step on a hedgehog unexpectedly when you communicate with another xmpp client or server.
because you buy our open-sourced bitcoin,\
we decided to offer you to buy our open-sourced messenger.\
ha-ha joke.\
it's free, really. GPLv3, whatever.
for Android, it's just an improved fork of Conversations,\
for iOS, it's our development from scratch,\
for Desktops we're polako [looking](xmpp:xmppclient-dev@conference.another.im). for devs.
all necessary XEP's was realized by Conversations devs but we added a cherry on top of this.\
on the server side we are offering free to use Prosody server,\
just connect to [another.im](xmpp:xmppclient-dev@conference.another.im), but we are encouroge you to don't trust us, self-host.
OTR encryption is also supported as 'secret chats' due to otr has been designed for one-time sessions and the concept of 'secret chats' fully corresponds to the idea of the OTR.
also you can just download <a href="https://dev.narayana.im/narayana/anotherim">the source code</a>, compile it and install.
only those who seeks will realize the way to pay us,\

#### How does the encryption for group chats work?
##### OMEMO
OMEMO encryption works only in private (members only) conferences that are non-anonymous. Non-anonymous (being able to discover the real JID of other participants) is a technical requirement to discover the key material. Members only is a sort of arbitrary requirement imposed by Conversations. (see 'OMEMO is grayed out')
The server of all participants need to pass the OMEMO [Compliance Test](https://conversations.im/compliance/).
In other words they either need to run ejabberd 18.01+ or Prosody 0.11+.
(Alternatively it would also work if all participants had each other in their contact list; But that rarely is the case in larger group chats.)
The owner of a conference can make a public conference private by going into the conference
details and hit the settings button (the one with the gears) and select both *private* and
*members only*.
##### OpenPGP
Every participant has to announce their OpenPGP key (see answer above).
If you would like to send encrypted messages to a conference you have to make
sure that you have every participant's public key in your OpenKeychain.
Right now there is no check in another.im to ensure that.
You have to take care of that yourself. Go to the conference details and
touch every key id (The hexadecimal number below a contact). This will send you
to OpenKeychain which will assist you on adding the key. This works best in
very small conferences with contacts you are already using OpenPGP with. This
feature is regarded experimental. another.im is the only client that uses
XEP-0027 with conferences. (The XEP neither specifically allows nor disallows
this.)
#### What is Blind Trust Before Verification / why are messages marked with a red lock?
Read more about the concept on https://gultsch.de/trust.html
#### I found a bug
Please report it to our XMPP conference [`xmppclient-dev@conference.narayana.im`](xmpp:xmppclient-dev@conference.narayana.im).

Easy to use, reliable, battery friendly. With built-in support for images, group chats and e2e encryption. the Another Instant Messenger is not a messenger,
don't believe the words.
Design principles: we just offer you a standardized xmpp-client with predicted features which work equally on all platforms.
in our clients we have realized pure XMPP and you won't step on a hedgehog unexpectedly when you communicate with another xmpp client or server.
* Be as beautiful and easy to use as possible without sacrificing security or privacy because you buy our open-sourced bitcoin,
* Rely on existing, well established protocols we decided to offer you to buy our open-sourced messenger.
* Do not require a Google Account or specifically Google Cloud Messaging (GCM) ha-ha joke.
* Require as few permissions as possible it's free, really. GPLv3, whatever.
Features: for Android, it's just an improved fork of Conversations,
* End-to-end encryption with either <a href="https://en.wikipedia.org/wiki/OMEMO">OMEMO</a> or <a href="http://openpgp.org/about/">OpenPGP</a> all necessary XEP's was realized by Conversations devs but we added a cherry on top of this.
* Sending and receiving images on the server side we are offering free to use Prosody server,
* Encrypted audio and video calls (DTLS-SRTP) with DTMF dialpad just connect to [another.im](xmpp:xmppclient-dev@conference.another.im), but we are encouroge you to don't trust us, self-host.
* Intuitive UI that follows Android Design guidelines
* Pictures / Avatars for your Contacts
* Syncs with desktop client
* Conferences (with support for bookmarks)
* Address book integration
* Multiple accounts / unified inbox
* Builtin image editor
* Very low impact on battery life
XMPP Features: OTR encryption is also supported as 'secret chats' due to otr has been designed for one-time sessions and the concept of 'secret chats' fully corresponds to the idea of the OTR.
another.im works with every XMPP server out there. However XMPP is an extensible protocol. These extensions are standardized as well in so called XEPs. another.im supports a couple of those to make the overall user experience better. There is a chance that your current XMPP server does not support these extensions. Therefore to get the most out of another.im you should consider either switching to an XMPP server that does or - even better - run your own XMPP server for you and your friends. also you can just download <a href="https://dev.narayana.im/narayana/anotherim">the source code</a>, compile it and install.
These XEPs are - as of now: only those who seeks will realize the way to pay us,
we can offer you additional server-side features and some telecommunication magic on our <a href="https://narayana.im">narayana.im</a>
* XEP-0050: Ad-Hoc Commands lets to interact with gateways.
* XEP-0065: SOCKS5 Bytestreams (or mod_proxy65). Will be used to transfer files if both parties are behind a firewall (NAT).
* XEP-0163: Personal Eventing Protocol for avatars.
* XEP-0191: Blocking command lets you blacklist spammers or block contacts without removing them from your roster.
* XEP-0198: Stream Management allows XMPP to survive small network outages and changes of the underlying TCP connection.
* XEP-0215: External Service Discovery will be used to discover STUN and TURN servers which facilitate P2P A/V calls.
* XEP-0237: Roster Versioning mainly to save bandwidth on poor mobile connections.
* XEP-0280: Message Carbons which automatically syncs the messages you send to your desktop client and thus allows you to switch seamlessly from your mobile client to your desktop client and back within one conversation.
* XEP-0308: Last Message Correction allows you to edit last message as well as retract it.
* XEP-0313: Message Archive Management synchronize message history with the server. Catch up with messages that were sent while another.im was offline.
* XEP-0352: Client State Indication lets the server know whether or not another.im is in the background. Allows the server to save bandwidth by withholding unimportant packages.
* XEP-0363: HTTP File Upload allows you to share files in conferences and with offline contacts. Requires an additional component on your server.
* XEP-0461: Message Replies provides support of native replies, which also works in many transports (gateways) as well.

Надёжный, простой в использовании, сберегающий заряд аккумулятора. Обладает встроенной поддержкой изображений, групповых чатов и сквозного шифрования. Another Instant Messenger - это не просто мессенджер,
не верьте слухам.
Принципы проектирования: Мы просто предлагаем вам стандартный XMPP-клиент с предсказуемым функционалом, который одинаково работает на всех платформах.
В наших клиентах мы реализовали чистый XMPP, и вы не столкнетесь в неожиданными проблемами, при общении с другими XMPP-клиентами или серверами.
* Быть предельно красивым и простым в использовании, не жертвуя безопасностью или конфиденциальностью когда то вы купили биткойн из-за его открытого кода,
* Полагаться на существующие, устоявшиеся протоколы поэтому мы решили предложить вам купить наш мессенджер с открытым исходным кодом.
* Не требовать учётной записи Google, в частности Google Cloud Messaging (GCM) Шутка.
* Требовать как можно меньше разрешений Он бесплатный, правда. GPLv3, по...
Функции: Для андройд это просто улучшенный форк Conversations,
* Сквозное шифрование (от отправителя к получателю) при помощи <a href="https://en.wikipedia.org/wiki/OMEMO">OMEMO</a> или <a href="http://openpgp.org/about/">OpenPGP</a> Все необходимые XEP'ы были реализованы разработчиками Conversations, но мы добавили вишенку сверху.
* Отправка и получение изображений На стороне сервера мы предлагаем бесплатный сервер на базе Prosody,
* Зашифрованные голосовые и видеозвонки (DTLS-SRTP) с DTMF-клавиатурой просто подключитесь к [another.im](xmpp:xmppclient-dev@conference.another.im), но мы призываем вас не доверять нам, используйте собственный хостинг.
* Интуитивно понятный интерфейс пользователя, соответствующий указаниям Android Design
* Изображения / Аватары для Ваших контактов
* Синхронизация с настольным клиентом
* Конференции (с поддержкой закладок)
* Интеграция адресной книги
* Несколько учётных записей / единая папка входящих
* Встроенный редактор изображений
* Крайне низкое влияние на время жизни от аккумулятора
Функции XMPP: Шифрование OTR также поддерживается как «секретные чаты», поскольку OTR был разработан для одноразовых сессий, а концепция «секретных чатов» полностью соответствует идее OTR.
another.im работает с любым сервером XMPP. Однако, XMPP — расширяемый протокол. Расширения также стандартизированы в так называемых XEP. another.im поддерживает некоторые из них, дабы улучшить общий опыт использования. Может оказаться, что Ваш текущий сервер XMPP не поддерживает эти расширения. Поэтому, чтобы получить максимум от another.im, рассмотрите переход на XMPP-сервер с поддержкой этих расширений, или — ещё лучше — запускайте собственный сервер XMPP для себя и своих друзей. также вы можете просто скачать <a href=«https://dev.narayana.im/narayana/anotherim»>исходный код</a>, скомпилировать его и установить.
В настоящее время поддерживаются такие XEP: только те, кто ищет, поймут, как нам платить,
мы можем предложить вам дополнительные услуги и немного телекоммуникационной магии на нашем <a href=«https://narayana.im»>narayana.im</a>.
* XEP-0050: Контекстные Команды, позволяет взаимодействовать с мостами.
* XEP-0065: Байтовые Потоки SOCKS5 (либо mod_proxy65). Используется для передачи файлов, если обе стороны находятся за брандмауэром (NAT).
* XEP-0163: Персональный Протокол Событий, для аватаров.
* XEP-0191: Команда Блокировки, позволяет Вам заносить спамеров в чёрный список или блокировать контакты, не удаляя их из своего списка.
* XEP-0198: Управление Потоками, позволяет XMPP выдерживать небольшие перебои в сети и смены основного TCP-соединения.
* XEP-0215: Поиск Внешних Сервисов, позволяет находить STUN- и TURN-сервера, когда аудио-/видеозвонок невозможно осуществить напрямую.
* XEP-0237: Версионирование Списка Контактов, прежде всего для сберегания мобильного трафика.
* XEP-0280: Сообщения под Копирку, автоматически синхронизирует отправленные сообщений на настольный клиент, чем позволяет плавно переключаться между мобильным и настольным клиентами в рамках одного разговора.
* XEP-0308: Исправление Последнего Сообщения, позволяет отредактировать или отозвать сообщение.
* XEP-0313: Управление Архивом Сообщений, синхронизирует историю сообщений с сервером. Узнавайте о сообщениях, отправленных, пока another.im находился оффлайн.
* XEP-0352: Индикация Состояния Клиента, сообщает серверу, работает ли another.im в фоновом режиме. Позволяет серверу сберегать пропускную способность, удерживая неважные пакеты.
* XEP-0363: Загрузка Файлов по HTTP, позволяет обмениваться файлами в конференциях и с оффлайн-контактами. Требует дополнительного компонента на Вашем сервере.
* XEP-0461: Ответы на Сообщения, предоставляет поддержку привязанных к сообщению ответов, которые также работают со многими транспортами (мостами).

Функції: Для андройд це просто покращений форк Conversations,
* Наскрізне шифрування (від відправника до одержувача) за допомогою <a href="https://en.wikipedia.org/wiki/OMEMO">OMEMO</a> або <a href="http://openpgp.org/about/">OpenPGP</a> Всі необхідні XEP'и були реалізовані розробниками Conversations, але ми додали зверху вишні (дивовижні).
* Надсилання та отримання зображень На боці сервера ми пропонуємо безкоштовний сервер на базі Prosody,
* Зашифровані голосові та відеодзвінки (DTLS-SRTP) з DTMF-клавіатурою просто підключіться до [another.im](xmpp:xmppclient-dev@conference.another.im), але ми закликаємо вас не довірять нам, використовуйте власний хостинг.

* Вбудований редактор зображень
* Дуже низький вплив на термін служби акумулятора
Функції XMPP: Шифрування OTR також підтримується як «секретні чати», оскільки OTR був розроблений для одноразових сесій, а концепція «секретних чатів» цілком відповідає ідеї OTR.
another.im працює з будь-яким сервером XMPP. Проте XMPP — розширюваний протокол. Розширення також стандартизовані в так званих XEP. another.im підтримує кілька з них, щоб покращити загальний досвід користування. Може виявитися, що Ваш поточний сервер XMPP не підтримує цих розширень. Тому, щоб отримати максимум від another.im, розгляньте перехід на XMPP-сервер з підтримкою цих розширень або — ще краще — запускайте власний сервер XMPP для себе і своїх друзів. також ви можете просто скачати [вихідний код](https://dev.narayana.im/narayana/anotherim), скомпілювати його і встановити.
На даний час підтримуються такі XEP: тільки ті, хто шукають, збагнуть, куди в нас гроші запихувати,
ми можемо запропонувати вам додаткові послуги і трішки телекомунікаційної магії на нашому [narayana.im](https://narayana.im).
* XEP-0050: Контекстові Команди, дозволяє взаємодіяти з мостами.
* XEP-0065: Байтові Потоки SOCKS5 (або mod_proxy65). Використовується для передачі файлів, якщо обидві сторони знаходяться за брандмауером (NAT).
* XEP-0163: Персональний Протокол Подій, для аватарів.
* XEP-0191: Команда Блокування, дозволяє Вам заносити спамерів у чорний список або блокувати контакти, не видаляючи їх зі свого списку.
* XEP-0198: Керування Потоками, дозволяє XMPP витримувати невеликі перебої в мережі та зміни основного TCP-з'єднання.

* XEP-0237: Версіонування Списку Контактів, передусім для заощадження мобільного трафіку.
* XEP-0280: Повідомлення під Копірку, автоматично синхронізує надіслані повідомлення на настільний клієнт, чим дозволяє плавно перемикатися між мобільним і настільним клієнтами в рамках однієї розмови.
* XEP-0308: Виправлення Останнього Повідомлення, дозволяє відредагувати чи відкликати повідомлення.
