Adding Additional DIDs

To associate all other DIDs/Numbers you have in your Aatrox Communications account with 3CX, go to the Management Console → SIP Trunks, double-click on your Aatrox Communications 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 a national number format (e.g. 61285203570) 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.

Number Formats:

General:

When configuring our SIP Trunks in 3CX, all numbers should be entered in a national number format (e.g. 0285203570), otherwise, call routing will fail.

Outbound Caller ID:

Our Trunks does not support Clip No Screening which means you can only present numbers as Outbound Caller ID that are assigned to your trunk. These numbers must be presented in a national format (e.g. 61285203570).

Outbound Rules:

When configuring your Outbound Rules make sure that all numbers are dialled either in the National (e.g. 61285203570) or International (e.g. 001161285203570) format.
