Setting Description
Transport
Protocol Indicates the protocol the system uses for SIP signaling.
The SIP network infrastructure in which your VSX system is
operating determines which protocol is required. For example, if
your VSX system is operating in a Microsoft® Live
Communication Server (LCS) SIP network, choose TCP. If your
VSX system is operating in a Nortel Multimedia Communication
Server (MCS) SIP network, choose UDP.
User Name Specifies the system’s SIP name. If you leave this field blank, the
system’s IP address is the SIP user name.

Registrar
Server Specifies the DNS name or IP address of the SIP Registrar
Server.
