Help with 3CX v20 – Office Hours & DND Behavior Issue

[ngri]

Hello everyone,

I’m using 3CX v20 and facing two main issues:

1. Office Hours for External Calls Only:
   I need to apply office hours logic to inbound calls so that only external callers are routed to extension 20 during business hours, and then sent to voicemail outside of business hours. I’m not sure how to configure 3CX so it applies this rule exclusively to external callers.
2. Strange Behavior When Extension 20 Is in DND:
   When extension 20 is set to “Do Not Disturb,” inbound calls trigger an unexpected sequence (as shown in the screenshot below). It forward to vmail and vmail forward to an other extension. This is not the behavior we want.

Could anyone point me in the right direction to set up these rules correctly and fix the DND forwarding issue?

Thank you!

1. Use the department menu. Assign the DID there and routing there. Then just set the hours for it.

2. Check that the extension is not set as the Operator extension in the system's voicemail settings.
