Traditional PSTN phone lines are still a great method to make calls and in some regions the only way. Either the internet does not permit it or traditional telecom providers provide phone lines via an entrance on facility only. These lines then require to be plugged into a VoIP Gateway and linked to 3CX. You can learn more about VoIP Gateways here - What is a VoIP Gateway

Which VoIP Gateway?

Whilst 3CX does not directly support VoIP Gateways, we do advise the list below manufacturers: Patton, Beronet and Grandstream.

These suppliers check their products with 3CX and are familiar with it. For any technical assistance you have to speak straight with the vendor in question. The available technical assistance for the entrance ought to be a crucial point in the purchasing decision!

How it Works

The general reasoning of configuring a VoIP gateway is to configure the gateway as a SIP trunk into 3CX. It's not actually a SIP Trunk due to the fact that the instructions of registration is various. A SIP Trunk will constantly be configured to permit 3CX to register to it. The VoIP entrance SIP trunk signs up with 3CX. Some VoIP Gateways now permit IP based registration and might hence be configured as a routine SIP Trunk if you choose. This is the main distinction between a SIP trunk and a VoIP gateway and the reason that you need to select "Add Gateway" and not "Add SIP Trunk".

Step 1: Connect the VoIP Gateway

Connect the VoIP Gateway to the network.

Now find the entrance's network IP:

For a Grandstream, utilize the "Grandstream IP Discovery Tool".

For a Patton, utilize the "SmartNode" Discovery Tool.

For a Beronet, utilize the "bfdetect".


Login by means of the gadget's web interface.

Update the firmware to the current version.

Assign a fixed IP or create a booking on your DNS server. Keep in mind of this IP.

Step 2: Patton/ Beronet - Import template

If you do not have a Patton or Beronet entrance you can avoid this action.

The Inbuilt Generic Gateway Template has "Outbound Parameters" defined "FromUserPart" -> $CallerNum which works with numerous entrances but not with Patton and Beronet. If you have this brand name you need to import a particular template. To do this:

Download this template for Patton or Beronet.

Go to "Advanced" > "Templates" > "Provider Templates" > "Import".

Select the generic design template you downloaded and press import to configure this entrance.

Step 3: Configure your Gateway Trunk on 3CX

Specify a name for this entrance.

In "Registrar/Server" get in the entrance's IP.

Enter the entrance's "Main Trunk Number" and "Default Route".

Enter the variety of synchronised require this entrance. This should not go beyond the variety of lines the gateway supports, e.g. a T1 gateway supports 23 lines.

Go to the "DID numbers" tab and specify any DIDs linked to the PSTN connection you are connecting to the VoIP Gateway.

Take note of the Authentication ID and password.

Click "Save" to produce this entrance.

Step 4: Create an Outbound Rule for this Gateway

Enter a name for this outbound guideline.

Define the rule alternatives for the calls to be routed by means of this entrance.

Click "Save".

Step 5 - Register your Gateway to 3CX

Go to Authentication Services and include the authentication profile named "AS_ALL_LINES" with the Authentication ID and Password drawn from 3CX "Add Gateway" configuration.

Go to Location Services and add "LS_10000" where "10000" is your Authentication ID taken from 3CX "Add Gateway" configuration.

Go to Telephony > Call-Router and specify the Routing Tables based upon your device settings. You might speak to Patton to provide you with a detailed guide on how to configure your Routing Tables.
