This dial code (which is unspecified by default for security purposes) is a code that when used, will set the whole 3CX Phone System to either:

  1. In office hours
  2. Out of Office hours or
  3. Instruct the 3CX Phone System to fall back to the configured global office hours at that particular day and time.
This code is designed for emergency services when you need to change the routes of all your VoIP Lines to IN or Out of office quickly with a single phone call.


Usage of this Dial Code

Let us assume that the administrator configures this dial code to be *64.

Let us also assume that the global office hours are set from 9am till 5.30pm.


Setting 3CX Phone System to In Office Hours

If the Administrator dials *641 (appends a 1 to the code), a prompt will be played stating that the “3CX Phone System is now set to IN OFFICE HOURS”. This means that the 3CX Phone System will disregard the current time, or day (even if it is a holiday) and set all the routes of the Gateways, VoIP Providers and DID/DDI’s to route to the In Office hours destination.


Setting 3CX Phone System to Out of Office Hours

If the Administrator dials *642 (appends a 2 to the code), a prompt will be played stating that the “3CX Phone System is now set to OUT OF OFFICE HOURS”. This means that the 3CX Phone System will disregard the current time, or day (even if it is 10am for example) and set all the routes of PSTN Gateways, VoIP Providers and DID/DDI’s to route to the Out of Office hours destination.


Setting 3CX Phone System to Default Office Hours Operation

If the Administrator dials *64 (with nothing appended), a prompt will be played stating that the “3CX Phone System is now using the DEFAULT OFFICE HOURS”. This means that in this example, the 3CX Phone System will override the previous 2 commands and behave as follows – from 9am till 5.30pm lines/ports will be routed to In Office Hours destinations and from 5.31pm till 8.59am, the lines/ports will be routed to the Out of Office hour destinations.
