UC-P100-S & UC-P110-S-PLUS
Crestron Flex VoIP Desk Phones for
Skype® for Business
Introduction
The UC-PHONE-S & UC-PHONE-S-PLUS Crestron Flex VoIP Desk Phones for Skype® for
Business (respectively sold as UC-P100-S & UC-P110-S) are premium VoIP desk phones
designed for use with the Skype for Business intelligent communications platform. These
phones enable superior voice calling and full-duplex hands-free conferencing in a stylish
desktop package. A consistent user experience at every desk, workstation, and meeting
space is provided via the familiar and intuitive Skype® for Business touch screen UI,
affording simple operation with comprehensive call and contact management features,
built-in calendaring, and one-touch meeting joins.
This supplemental guide discusses the requirements and configuration instructions for
the UC-PHONE-S & UC-PHONE-S-PLUS phones. For information on installing these
phones, refer to the UC-PHONE-S/UC-PHONE-T Quick Start Guide (Doc 8358) and the
UC-PHONE-S-PLUS/UC-PHONE-T-PLUS Quick Start Guide (Doc 8359) at
www.crestron.com/manuals.
This guide is intended for administrators who need to properly configure, customize,
manage, and troubleshoot the Skype for Business phones. This guide will help with
understanding the Voice over Internet Protocol (VoIP) network and provides descriptions
of all available phone features. This guide describes three methods for configuring
phones: central provisioning, web user interface and phone user interface. The document
will provide information on the following:
•Configure a phone on a provisioning server
•Configure a phone’s features and functions via web/phone user interface
•Troubleshoot some common phone issues
Many of the features described in this guide involve network settings, which could affect
the phone’s performance in the network. An understanding of IP networking and a prior
knowledge of IP telephony concepts are necessary.
The information in this guide is for UC-PHONE-S and UC-PHONE-S-PLUS phones
running firmware version 55.9.91.1 or later.
Reading the Configuration Parameter Tables
Most features described in this guide include two tables. One is a summary table of
provisioning methods used to configure the features. The other contains configuration
parameters used to make the features work.

2•UC-P100-S/UC-P110-S Phones for Skype for Business Supplemental Guide – DOC. 8412A
This brief section describes the conventions used in the summary table and configuration
parameter table. In order to read the tables and successfully perform configuration
changes, an understanding of these conventions is necessary.
Summary Table Format
The following summary table indicates three methods; central provisioning, web user
interface, and phone user interface, that can be used to configure a feature. Note that
the types of methods used for each feature will vary.
The central provisioning method requires parameters to be configured in the CFG
format. Configuration files provided by Crestron Files can be downloaded from the
DOCUMENTATION section of each product page on the Crestron website. For more
information on configuration files, refer to “Configuration Files” on page 85. As shown
below, the table specifies the configuration file name and the corresponding parameters.
That is, the <MAC>.cfg file contains the account.1.auto_answer parameter, and the
<y0000000000xx>.cfg file contains the features.auto_answer_delay parameter.
The web user interface method requires configuring features by navigating to the
specified link. This navigation URL enables the user to quickly locate the webpage where
the feature can be configured.
Summary Table Format
Configuration Parameter Table Format
The following configuration parameter table describes how to configure a parameter to
make a feature (e.g., auto answer) work. The table also indicates three methods for
configuring the feature (parameter name, web user interface, and phone user interface).
