Defining a SIP Network Service in the Collaboration Server and Installing 
the Security Certificate 
Your RealPresence Collaboration Server system should be installed according to standard 
installation procedures. For details, see the Polycom® RealPresence Collaboration Server Virtual 
Edition Getting Started Guide
.
When configuring the Default IP Network Service on first entry, or when modifying the 
properties of the existing Default IP Network Service, the SIP environment parameters must be 
set as described in this section.
The Security Certificate
There are two methods to create and send the security certificate that is required for 
configuration of the integration of the Collaboration Server in the Microsoft environment:
The CSR method 
The PFX method (Recommended method for Lync Server, Wave 14)
The CSR Method
In the CSR method, the security certificate is created as part of the SIP Server configuration 
in the IP Network Service configuration.
Using the CSR Method, the following processes are performed:
Creating the certificate request (in the Default IP Network Service - SIP Server dialog box). 
Sending the certificate request to a Certificate Authority.
Receiving the certificate from the Certificate Authority.
Installing the certificate in the Collaboration Server (in the Default IP Network Service - 
SIP Server dialog box).
The PFX Method
In the PFX method, the security certificate is created in advance, in the Lync Server 
environment. 
For detailed description of this procedure in the Lync Server environment, see the Polycom 
Unified Communications Deployment Guide for Microsoft Environments
