Setting Description
Sign-in Address The SIP address or name of the system (for example, 
mary.smith@department.company.com). If you leave this blank, 
the system IP address is used for authentication.
User Name The user name for authenticating your system with a SIP 
registrar server (for example, marySmith). If the SIP proxy 
requires authentication, you can’t leave the user name and 
password blank.
Password The password associated with the user name for authenticating 
your system with a SIP registrar server.
Registrar Server The <IP_Address> can be an IPv4 address or an FQDN such as 
servername.company.com:5060.
Proxy Server The IP address or FQDN of the SIP proxy server. If you leave 
this field blank, the system uses the registrar server address. If 
you also leave the SIP registrar server field blank, there is no SIP 
proxy server to configure.
By default, the system sends SIP signaling to ports 5061 (TLS) 
and 5060 (TCP) on the proxy server.
The syntax for this setting is the same as the registrar server.
Registrar Server Type Specifies the type of SIP registrar server you’re using.
