**Pax Fax is a Nextcloud application that allows sending and receiving faxes in Nextcloud.**

A Phaxio or Sinch account and a real fax number acquired from Phaxio or Sinch are needed.

<span style="display:block;height:20px!important"></span>

## Features
<span style="display:block;height:10px!important"></span>

* 🚀 Multiple documents can be sent in one fax call (up to 20 separate files with a cumulative size of up to 20 MB).

* 📠 A fax can be sent to multiple fax numbers at once (up to 15 different fax numbers).

* 📄 Users can send as fax any document in any of the following formats: pdf, doc, docx, odt, jpeg/jpg, png, tiff/tif, txt, html.

* 📰 All incoming faxes are received as pdf documents and stored in a Nextcloud folder.

* 📧 Users receive notifications and (optionally) emails when new faxes arrive.

* 🔍 All the sent and received faxes are stored in specific Nextcloud folders, so that they can be searched by caller/callee phone number or date.

* 💻 When they want to send a fax, users can upload files from their computer or choose them directly from Nextcloud.

* 🔏 When using Phaxio, incoming fax requests are checked for authenticity and integrity by verifying Phaxio's signature.

* 💵 Current Phaxio balance can be always checked by pressing a button on the left panel.

* 💰 The only ongoing cost is $0.91 per month (Sinch) or $2 per month (Phaxio) for a fax number located in USA or Canada (Phaxio) or in USA, Canada or other countries (Sinch), in a city chosen by the user. No contracts.

* 💸 Straightforward pricing: $0.07 per sent/received page for faxes to/from USA and Canada and $0.1 per sent/received page for faxes to/from other countries.

## Browsers
<span style="display:block;height:10px!important"></span>

Pax Fax works with all the major browsers.

<span style="display:block;height:20px!important"></span>

## Programming Languages
<span style="display:block;height:10px!important"></span>

Pax Fax only uses PHP, SQL, jQuery, CSS and HTML. This means it's robust, efficient, light-weight and easy to maintain and debug.

<span style="display:block;height:20px!important"></span>

## Minimum Requirements
<span style="display:block;height:10px!important"></span>

- **Nextcloud 22+** has to be installed and properly configured, preferably by following the <a href="https://www.doublebastion.com/install-nextcloud/" rel="noreferrer noopener" target="_blank">Install Nextcloud</a> chapter in our guide.

- **A phaxio.com or sinch.com account and a fax number** associated with it.

- The **libcurl** PHP library has to be installed on the server (it's usually installed automatically when PHP is installed).

To enable email notifications for every received fax, the "sendmail" utility ("/usr/sbin/sendmail" on Debian Linux), has to be present on the server. "sendmail" is a binary which gets 
installed when Postfix is installed. Also, the web server user (www-data) has to be allowed to send emails from command line (by specifying "authorized\_submit\_users = www-data" in 
"/etc/postfix/main.cf" for Postfix on Debian).

digital freedom over the years and because centralized services create autonomy and privacy issues, in spite of all the benefits.
