Linksys SPA3102 Connectivity

As shown in the following figure, the SPA3102 has one FXS port (voice line 1).

SPA3102
By default, the device on the LAN port is assigned the network address 192.168.0.0 with a
subnet mask of 255.255.255.0. If there is a network address conflict with a device on the
Ethernet port, the network address of the device on the LAN port is automatically changed to
192.168.1.0.
Notes:
• The IVR functions are accessed by connecting an analog telephone to Line 1.
• For proper operation, the service provider should use an Outbound Proxy to forward all
voice traffic when the SPA3102 is located behind a router. If necessary, explicit port ranges
can be specified for SIP and RTP.
