Prerequisites
In order to perform a secure configuration, the following prerequisites must be met.
Operating Environment
Crestron assumes the following about the operating environment of its systems:
l
The system is not capable of Multi-Factor Authentication (MFA). If your organization's
policy requires MFA, you cannot use the system.
l
Physical security is commensurate with the value of the system and the data it contains
and is assumed to be provided by the environment.
l
Administrators are trusted to follow and provide all administrator guidance.
Firmware Version
Crestron Flex Phones must be running firmware version 1.0.4.22 or later.
Device Access
The administrator can access and configure the device by using a web browser. Additionally,
some aspects of configuration can be performed via the XiO Cloud® service. This document
describes device configuration using the web browser.
The device also provides local setup pages for commonly used configuration settings. The local
setup pages can be accessed from the touch screen display by tapping the gear icon on the home
page and then selecting Device Settings.
Default Configuration Settings
In order to configure the device, it must first be placed in its factory default state. A device can
be returned to this state as follows:
1. Disconnect the Ethernet cable from the LAN port that supplies the device power over PoE
(Power over Ethernet).
2. Reconnect the Ethernet cable to the LAN port. The device starts to boot.
3. When the LED light bar below the touch screen display starts to flash green, press and
hold the Volume Up and Microphone Mute buttons simultaneously for at least 10 seconds.
A page is displayed asking whether a factory restore should be performed.
