Configuring SIP Settings
The Session Initiation Protocol (SIP) is a signaling protocol for Internet
conferencing.
If you are unfamiliar with SIP, Polycom recommends that you do not change the
default settings.
To configure the SIP settings if your network supports SIP:
1. Go to System > Admin Settings > Network > IP > SIP Settings.
2. Configure these settings:
Setting Description
Enable SIP Check this to allow the system to make calls using SIP.
Transport Protocol Select the protocol the system uses for SIP signalling.
The SIP network infrastructure in which your V500 system is
operating determines which protocol you should choose. For
example, if your V500 system is operating in a Microsoft Live
Communication Server (LCS) SIP network, choose TCP. If your
V500 system is operating in a Nortel Multimedia Communication
Server (MCS) SIP network, choose UDP.
Password Enter the password that authenticates the system to the Registrar
Server.
User Name Enter the system’s SIP name or leave this field blank if you want
to use the system’s IP address as the SIP user name.
Proxy Server Enter the DNS name or IP address of the SIP Proxy Server, or
leave this field blank if no proxy server is used.
By default, the SIP signalling 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 Enter the name or IP address of the SIP Registrar Server.
