New Setup - Ext 100

[DCLLC]

So, I just spun up a 2 month demo of 3CX which we will be moving to in July from our current PBX solution. It has set me up with Ext 100 which it does not allow me to change. I tried to create a 2nd system owner account but my e-mail address is already in use. The issue is that we do use Ext 100 for a real person in our office that isn't me. I need to change Ext 100 to a different number (another 1xx) so that I can assign 100 to an end user.

I can't seem to figure out how to change it. Any help would be great. Thanks!

You cannot change an existing extension number. However you can create a new system owner, verify it works (!), and then set x100 to User level or delete and recreate it.

Exactly as @SteveITS mentioned.
