Follow these steps to set up a LinkSys SPA-3102 VoIP
Gateway with 3CX
Phone System:
- Ensure that you have created the PSTN line in 3CX Phone
System first. Take note of the Authentication ID field and
the Authentication password that you have entered for the
line connected to the VoIP Gateway.
- Connect the LinkSys SPA-3102 gateway to the network and
mains power supply. The device will boot up, and providing
you have DHCP installed on your network, will obtain an IP
address. To get the exact IP address, check the most recent
DHCP lease, or alternatively use a network scanner to find a
device with the string ‘LinkSys’.
- Another way to find the IP address would be to connect
an analog phone to the “phone” port and press “****”. This
would take you to the LinkSys Interactive Voice response
menu. From there you press 110# or 210# to check the
external (internet port) or internal (Ethernet/local port)
IP address respectively.
- Now point your browser to the gateway’s configuration
site: ‘http://x.x.x.x’, where “x.x.x.x” is the IP address
leased by the DHCP server to the gateway or the IP that you
were just provided by the Interactive Voice Response menu.
- Once the page loads click on the “Admin Login” link on
the top right hand side of the page. This will provide the
basic administration configuration version of the interface.
Now click on the “advanced” link on the top right hand side
of the page. This will provide the advanced administration
configuration version of the interface.
- One thing to have in mind is that if you are planning to
use this device just as a VoIP gateway, then you don’t need
to configure the Ethernet(local or yellow) interface; just
the Internet (external or blue) interface.
- Now click the “ROUTER” and after that the “WAN SETUP”
tab on the top of the page to configure an IP in your local
network. (Assuming you already have a router/internet
gateway and you just want to use this device as a VoIP
Gateway).

In the Proxy Registration section:
a. Set the “Proxy”
field to the IP address or FQDN of the server on which the
3CX Phone System is installed

c. The “Register Expires” field sets the
interval at which the gateway device will renew its line
registration with the 3CX Phone System Server. You can leave
the value at its default setting.

line connected to the gateway. Configure the line as
follows:
a. The “Display Name” should have a name assigned to it.
Choose a display name that will not match a possible number;
it also must NOT be blank. If this field is blank, or
matches the caller’s number, the device will operate in
2-stage dialing mode. Choosing an alphanumeric Display name
is a safe choice. E.g.: “SPA-3102” or “Outside Line”.
b.
In the “User ID” field, enter a name for the line.
c. Set
the “Use Auth ID” field to “yes”.
d. In the
“Authentication ID” and “Password” fields, enter the ID and
Password that you entered for the line in the 3CX Phone
System Management Console. These fields must match
the ID and password set for the line in the 3CX Phone System
Management Console.

In the Audio Configuration section, set the “Preferred
Codec” field to “G711u”.

-
In the Dial Plans section, set the “Dial Plan
8” field to “(S0<:yyyy>)” where yyyy must be replaced
with the ID that you entered for the line in the 3CX Phone
System Management Console. For example, if the ID used was
“10700”, the “Dial Plan 8” field must be set to
“(S0<:10700>)”.
-
In the VoIP-To-PSTN Gateway setup
section:
a. Set the “VoIP-To-PSTN Gateway Enable”
field to “yes”.
b. Set the “VoIP Caller Auth Method”

By default, the SPA-3102 will wait for 16 seconds before
delivering a call to a SIP device. To change this, In the
"FXO Timer Values (sec)" section change "PSTN Answer Delay"
to 0. This will set the gateway to answer calls
immediately.
-
Click on the “Submit All Changes” button at the bottom of
the page to save your settings and restart the device. The
other settings that were not discussed are optional and can
be left as default.
- After the gateway has restarted, switch to the 3CX Phone
System Management Console, and click on the Phone System
-> “Line Status” (This is the default page). In the
section “External Lines”, the PSTN line connected to the
VoIP Gateway should be listed with a green status light.
