Migrating from one PBX to another is not an easy task. It usually takes a lot of time for the Administrator to set up the new PBX to include all the extensions and users that the previous PBX had.
The good news is that if you’re migrating from an Asterisk® to 3CX we’ve made this process much easier. We’ve created an export module which you can easily upload onto your Asterisk® which will then export your extensions for you to upload them to 3CX version 14.
The entire process takes literally 5 minutes, saving you an amazing amount of time and work. Read this guide for the step by step procedure on how you can export your extensions. For any support questions please post questions on the 3CX forums.
