SPA2102 Connectivity
As shown in the following illustration, the SPA2102 has two FXS ports (voice lines
1 and 2).
By default, the device attached to the LAN port is assigned the network address
192. 1 68.0.0 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. 1 68. 1 .0.
•
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 SPA2102 is located behind a router. If
necessary, explicit port ranges can be specified for SIP and RTP.
