Deployment Guide for the Polycom CX700 IP Phone
14
The Polycom CX700 phone reset options are as follows:
•
Power cycle— Reboot the phone by removing and then reapplying power
•
Soft Reset—Press the reset button on the back of the phone just long
enough to reset it
•
Hard Reset - Unplug the phone, use a paper clip to press and hold the reset
button (small hole on back between USB and Headphone jack), reapply
power (while continuing to hold down the reset button) until the scroll bar
on the display goes all the way across the screen. Then release the reset
button and within 30 to 120 seconds, the display should change to the
white calibration screen with the large plus sign in the center.
This process removes any credentials, certificate chains and XML
configuration files and restores the phone to factory defaults.
The first time a user powers up the phone and signs in, the phone gets in-band
provisioning information from the server or Enterprise pool hosting the user's
account. The information contains the internal and external URL of the server
running Device Update Service.
For example, this is the payload from a packet returned by the pool indicating
the location of the cpe.nbt file for both internal and external phones (some code
has been removed for clarity):
Http: Response, HTTP/1.1, Status Code = 200, URL:
