RingLogix is proud to be part of a select group of Providers that have been officially tested and certified by 3CX.
Before configuring the SIP trunk it is required to go through the following checklist and make changes where necessary:
Further setup information can be found in our Academy: 3CX Academy Basic Course
Some providers gained support and compatibility with 3CX on a specific product version. It is advisable to always run the latest version of 3CX to ensure ongoing compatibility.
Minimum 3CX Version: 3CX Phone System 16.0
Below is a short overview of the provider's capabilities and services and whether they’re supported or not:
Configuring the Trunk with 3CX
The general instructions outlining how to add a new SIP Trunk to your 3CX installation can be found here.
Adding the Trunk
Go to “SIP Trunks” and select “Add SIP Trunk”
Under the “General” tab in the “Authentication” section, enter your Authentication ID and Password as well as the registrar address (these will be supplied to you by RingLogix).
Adding Additional DIDs
To associate all other DIDs/Numbers you have in your RingLogix account with 3CX, go to the Management Console → SIP Trunks, double-click on your RingLogix Trunk and go to the “DIDs” tab
Here you should already see 1 entry; that is the Main Trunk number you have set. Add all other DIDs/Numbers you have to the list in the national number format (e.g. 987654321) and press OK.
Creating Inbound Rules
Now that you have associated all your DIDs/Numbers with your SIP Trunk in 3CX, you can create Inbound Rules to set where calls will be routed when those numbers are called. Instructions on how to create Inbound Rules can be found here.
When configuring RingLogix SIP Trunks in 3CX, all numbers should be entered in the national number format (e.g. 987654321), otherwise call routing will fail.
Outbound Caller ID
RingLogix trunks support Clip No Screening which means you can present any number that is assigned to the Trunk as the Outbound Caller ID.
When configuring your Outbound Rules, numbers can be dialed in all valid number formats. More information about how to create Outbound Rules and how they work can be found here.
