Tutorials: E.164: New Build/Configuration (Version 18)
Learn how to configure E.164 in a new build/configuration of 3CX!
Required Access: 3CX
Open the "SIP Trunks" tab.
Add a new SIP trunk.
Under the General tab, add your Main Trunk No as +1 (your DID) ex. +17019299797
If you have more DIDs, click on the "DIDs" tab at the top and add other DIDs in the same format.
Click "OK" at the top to save changes.
Any Outbound Caller IDs you set will need to have the +1.
You can follow our 3CX version 20 guide, Add Outbound Rules (V20) for setting up outbound rules so you do not need to dial +1 when calling out of the system.
