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.
