Deployment Guide for the Polycom CX700 IP Phone

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: /RequestHandler/ucdevice.upx

ProtocolVersion: HTTP/1.1
