Backup Registrar 
Server
Specify the IP address or DNS name of a backup SIP registrar server for the network
Transport Protocol Indicates the protocol the system uses for SIP signaling. The SIP network infrastructure 
determines which protocol is required.
• Auto enables an automatic negotiation of protocols in the following order: TLS, TCP, 
UDP. This is the recommended setting for most environments.
• TCP provides reliable transport via TCP for SIP signaling.
• UDP provides best-effort transport via UDP for SIP signaling.
• TLS provides secure communication of the SIP signaling. TLS is available only when 
the system is registered with a SIP server that supports TLS. When you choose this 
setting, the system ignores TCP/UDP port 5060..
SIP Server Type Specify whether the SIP registrar server is a Microsoft Office Communications Server or 
a Microsoft® Lync™ Server 2010. Enabling this setting activates integration features 
such as the Microsoft global directory and Office Communicator contact sharing with 
presence.
Verify Certificate Enable this option when the endpoint system’s certificate should be verified by the 
certificate authority.
Use Enterprise 
Credentials
Enable this option when the endpoint system should use the credentials the user entered 
at the endpoint to use for authenticate when registering with a SIP registrar server.
User Name Specify the name to use for authentication when registering with a SIP registrar server, 
for example, 
msmith@company.com
. If the SIP proxy requires authentication, this field 
and the password cannot be blank.
Password Specify the password that authenticates the system to the registrar server.
Provisioning Settings
Provisioning Polling 
Interval (minutes)
Specify the frequency at which the endpoint systems poll the CMA system for new 
provisioning information. 
By default, this interval is 60 minutes. For performance reasons, the minimum positive 
value for this interval is 5 minutes. There is no maximum value enforced. When the value 
of this interval is set to 0, the endpoint systems do not poll the CMA system for new 
provisioning information. 
Software Update 
Polling Interval 
(minutes)
Specify the frequency at which the endpoint systems poll the CMA system for a new 
software update package. 
By default, this interval is 60 minutes. For performance reasons, the minimum positive 
value for this interval is 5 minutes. There is no maximum value enforced. When the value 
of this interval is set to 0, the endpoint systems do not poll the CMA system for a new 
software update package.
Quality of Service Settings
Video Type of Service 
Value
Specify the IP Precedence or Diffserv value for video packets.
Audio Type of Service 
Value
Specify the IP Precedence or Diffserv value for audio packets.
Field For the endpoint systems at the site being provisioned...
