This document describes the steps necessary to get a Grandstream 42XX 16, 24, 32 or 48 port FXS Gateway working with a UCx Server.
If the Gateway is connecting to a UCx Cloud Server, you just need the following additional settings:
-
Ensure NAT is set to Yes for the UCx extension. (see Step One)
-
Ensure NAT is set to Yes on the profile page of the FXS Gateway. (see Step Four)
-
Ensure NAT settings on the SIP Settings page is set to Static IP and Auto Configure is applied. (see Step Five)
-
Operational UCx Server
-
Extensions on the UCx server programmed as SIP devices

If the FXS Gateway is connected to a UCx Cloud Server, change the nat field to Yes. Otherwise you can leave it at the default value No.
-
Press the Submit button at the bottom of the page and then the Apply Config bar.
-
Plug one end of the Network Cable into the WAN Port on the back of the 42XX device,
-
Connect the other end of the network cable to your network.
-
Plug an Analog Telephone into the RJ-21 port on the back of the 42XX device with a RJ11 to R21 cable.
-
Connect the Power cube to the 42XX device.
-
Plug the power cord into an AC wall outlet and allow the system to power up.

Press the pound key # and hang up.
-
Open a Web Browser window and connect to the IP Address of the 42XX device.

On the Status -> Port Status page and it will show the ports as Not Registered.
-
Navigate to Profile 1 -> General Settings page and set the SIP Server and Outbound Proxy fields to the IP address of the UCx server and click on the Save button.

Press the Save and Apply button at the bottom of the page and reboot the device.
-
Login to the device and check the status screen - you should see your port(s) Registered.
If the FXS Gateway is connecting to a UCx Cloud Server, complete Step Five first and then return to check the port status.
Step Five: NAT Settings for UCx Cloud
This step is needed only if the FXS Gateway is connecting to a UCx Cloud Server.
A common setting to configure on the FXS Gateway is the Dial Plan. You want to add dial patterns to allow dialing of feature codes, restrict certain dial patterns or use the # key to dial.
For example, a common North American dial plan is { ^1900x. | <=213>[2-9]xxxxxx | 1[2-9]xx[2-9]xxxxxx | 011[2-9]x. | [3469]11 | *x+ } where
