Creating Inbound Rules

Inbound rules determine where calls will be routed when that number is called.

 

  1. Navigate 3CX Management Console > “Inbound Rules”
  2. If inbound rule already exists for your DID, 3CX Inbound Rulesdouble click to edit. Otherwise, select “Add DID Rule“.
  3. Enter a name for the DID. This can be added to Caller ID through “Contacts” > “Options“.
  4. Select option from the “DID” field.
    • If wanting to add a DID that is not listed, enter the DID number in the SIP “to” header.
  5. Specify where calls go during and outside of business hours. You can configure specific office hours from “Setup Specific Office Hours for this Trunk“.
  6. “Play Holiday Prompt on Public Holiday” can be checked if you intend on playing a holiday message on public holidays.
  7. Click “OK” to create this inbound rule.

Number Format

General

All numbers should be entered in a national number format (e.g 0398765432), otherwise routing will fail.

Outbound Caller ID

Aatrox Communications does not support Clip No Screening (changing which outbound number is displayed), so you may only display the numbers that are assigned to your SIP trunk. These numbers must be entered in a national format (0398765432).

Outbound Rules

Outbound rules determine how outgoing calls will be routed.

Ensure all numbers are dialed in either a national or international format.
