Who Done It ?

[henington]

At some point, a little check box was Un-ticked. Kind of an important one. The one that says Allow Inbound Calls on the trunk.

How can I find info about when that occurred and under which account?

 

[Saqqara]

You will never find out, 3CX does not log this type of info.

 

[henington]

well hell... ok. No logs that would say, Option Allow Inbound Calls Enabled or anything in the management or service logs?

@henington

I know this is a technically correct but a completely useless answer, but...

Someone with admin privileges. This isn't an available option unless:

A - You are logging in under the admin account
B - You are logging in under an extension that has been granted the ability to modify trunk settings.

Hope that narrows it down for you.

Given the above information...if you can figure out exactly when inbound calls began (Activity Log?), and perhaps who this change would benefit, you may be able to narrow it down to a limited group of "suspects"

 

[cobaltit]

Take the information @Marari posted and you can check with your provider when calls failed and that will narrow down the time frame. You technically should be able to check the nginx access logs to get an IP address and that would help you track it down.

FWIW: There is a request to create a Change Log within the 3cx Management Portal to automatically track changes like this.

You can also set the PBX to send an email to the admin when a user (not using the admin account) logs in to the management console. The option is under Settings / Mail / Notifications
