Requirements

The **requirements** are:

* to have a microphone and headphones for your PC,
* to configure your *XiVO PBX*:

  * open WebRTC access (see::ref:`configure_xpbx_webrtc`) taking *great care of the security notice*,
  * and then create users with a WebRTC line (see: :ref:`configure_user_with_webrtc_line`),

* have a SSL/TLS certificate signed by a certification authority installed on the nginx of *XiVO CC* (see: :ref:`webrtc-ssl-cert`),
* and use *https*:

  * *Web Assistant*: you must connect to the *Web Assistant* via `https` protocol,
  * *Desktop Application*: you must check *Protocol -> Secure* in the application parameters.

.. note:: Currently you can not have a user configured for both WebRTC and a phone set at the same time.

Limitations
===========

Known limitation are :

* Voice may not be able to hear if your computer have more than 4 network interfaces up at the same time (this can happen if you use virtualization)

.. note::

  | To check if you have more than 4 network interfaces you can type following command:
  | ``ls /sys/class/net``

  | Then just use:
  | ``ifdown <ifname>``

  | This will switch off network interface not required to make your call.
