Linksys SPA8000 Connectivity

As shown in the following illustration, the SPA8000 consists of eight voice ports (voice lines 1-8).

IVR (Line 1 or
Line 2) SPA8000
By default, the device on the AUX 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 AUX port is automatically changed to
192.168.1.0.
In the illustration, one fax machine is connected to each pair of ports to illustrate that only one
T.38 connection is supported by each of the four pairs of RJ-11 ports. Up to four fax machines
can be connected to the SPA8000 router, but they must be distributed as shown.
Notes:
• With the SPA8000, use line 1 or line 2 to access the IVR functions. See the SPA8000 Quick
Installation Guide for IVR instructions.
• For proper operation, the service provider should use an Outbound Proxy to forward all
voice traffic when the SPA8000 is located behind a router. If necessary, explicit port ranges
can be specified for SIP and RTP.
• The SPA8000 is not designed to forward IP packets to devices connected to its AUX port and
that configuration is not supported.
• The SPA8000 also can be configured with trunk groups and trunk lines. See
and Hunt Groups on the SPA8000, " on page
