Setup Guide to the Linksys SPA­3102 ­ VoipSpeak
Incoming Settings
User Context: SPA3102_In
USER Details:
allow=ulaw
canreinvite=no
context=from­pstn
disallow=all
host=192.168.0.252
insecure=very
nat=yes
port=5060
type=user
In the incoming settings, the host address needs to be the IP address of your
Asterisk/trixbox PBX system, again use nat=yes if the SPA­3102 is on another subnet or
nat=no if the SPA­3102 is on the same subnet as the PBX.
Submit your changes and click the red apply bar, your trixbox/FreePBX system is ready
to go, now you need to configure the SPA­3102.
SPA­3102 Configuration
On the rear of the SPA­3102 are four ports, you should plug the
phone line into the line port, an analog phone into the phone port,
and connect a cable from the Ethernet port to your computer. This
will assign your computer an IP address, then you can access the
web interface of the SPA­3102 at http://192.160.0.1.
If you want the device to sit on your network and not hand out
DHCP addresses, plug your regular network into the Internet port, if you have a DHCP
server it will assign an IP address to the device or you can set it manually. If you are
putting it as a device on your network, be sure and turn on Enable WAN Web Interface
otherwise the only way to configure it is to plug a cable from the device to a computer.
Here comes the fun
Now, to configure it as a SIP trunk (this article does explain how to use it as an ATA) you
need to click on the Voice tab, and then on the PSTN Line tab, all of the settings are
going to changed here.
Proxy and Registration
This section tells the SPA­3102 how to handle calls back and forth, since we are not
using authentication, we need to disable those settings. First, set the Proxy setting to
point to IP address of your PBX box, then change the settings in the section to match the
list I will give you here, you should only have to adjust a few settings, but I will give you
all of them to make sure you have everything setuip right:

Use DNS SRV: No
Proxy Fallback Intvl: 3600
Use OB Proxy in Dialog: Yes
