Setting Description
SIP Server Specifies whether to automatically or manually set the SIP
Configuration server's IP address.
If you select Auto, the two server address fields that follow
cannot be edited. If you select Specify, those fields are
editable.
Registrar Server Specifies the IP address or DNS name of the SIP Registrar
Server.
• In a Microsoft Office Communications Server 2007 R2 or
Microsoft Lync Server 2010 environment, specify the IP
address or DNS name of the Office Communications
Server or Lync Server.
• If registering a remote HDX system with an Office
Communications Server Edge Server or Lync Server
Edge Server, use the fully qualified domain name of the
access edge server role.
By default for TCP, the SIP signaling is sent to port 5060 on
the registrar server. By default for TLS, the SIP signaling is
sent to port 5061 on the registrar server.
Enter the IP address and port using the following format:
<IP_Address>:<Port>
<IP_Address> can be an IPv4 address or a DNS hostname
such as servername.company.com:6050. Hostnames can
resolve to IPv4 or IPv6 addresses.
Note: If you have installed the RTV option key, this setting is
named Server name or IP address.
Syntax Examples:
• To use the default port for the protocol you have selected:
10.11.12.13
• To specify a different TCP or UDP port:
10.11.12.13:5071
Enter an IPv6 address using the following format:
[<IPv6_Address>]:<Port>
An example of an IPv6 address is:
