Discover Automatically:
The Discover Automatically radio button enables the SPA400 to learn the IP address
and the UDP port of the SPA9000 the from the SIP Registration packets sent by
SPA9000.
Static Address:
It is preferred that the SPA400 is configured with a static IP address. Enter the IP
address and the UDP port of the SPA9000 to enable the SPA400 to listen for the SIP
Registration request from the SPA9000
If the SPA9000 obtains an IP address from a DHCP server, it is preferred that the
“Discover Automatically” option is selected to avoid registration failure due to
SPA9000 IP address changes.
Figure 1 and Figure 2 reflect the web-based configuration utility for the SPA400 and
