If your network supports the Session Initiation Protocol (SIP), you can use SIP to
connect IP calls.
To specify SIP Settings:
1. Go to System > Admin Settings > Network > IP > SIP Settings.
2. Configure these settings:
Setting Description
Enable SIP Allows the system to make calls using SIP.
Transport Indicates the protocol the system uses for SIP signaling.
Protocol
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.
Password Specifies the password that authenticates the system to the
Registrar Server.
Proxy Server Specifies the DNS name or IP address of the SIP Proxy Server. If
you leave this field blank, no proxy server is used.
By default, the SIP signaling is sent to port 5060 on the proxy
server. To specify a different port, add it to the address as shown
here:
255.255.255.255:5070
Registrar Server Specifies the name or IP address of the SIP Registrar Server.
By default, the SIP signaling is sent to port 5060 on the registrar
server. To specify a different port, add it to the address as shown
here:
255.255.255.255:5070
