How To Create Outbound Rules in 3CX V20

1. Access the 3CX Management Console

Log in to your 3CX Management Console as administrator.

2. Navigate to Outbound Rules

From the left-hand menu, click on the "Outbound Rules" tab.

3. Creating Outbound Rule

• Go to “Outbound Rules”, select “Add”, and enter a name for the new rule.

Specify the conditions which should trigger this outbound rule:

• Calls to numbers starting with prefix - Any numbers starting with for example “9”.

• Calls to numbers with a length of - For example 8 digits, to differentiate between local and national numbers.

ℹ️You can make the rule for a specific extension in Calls from extension(s). Define the extension(s) or extension range separated by commas and ranges using “-”, e.g. 100,102-120.

You can also specify a whole department by clicking the Add button after Calls from departments.

• Now in “Make outbound calls on” set the routes on which the calls should be placed, select the Telxi SIP trunk. If the first route is not available or busy, 3CX automatically tries the next route, until the call can be made or the default “Block Calls” route is reached.

You can transform the number that matches the outbound rule, before the call is routed:

• Strip Digits - removes one or more digits from the called number, e.g. strip one digit to remove the prefix “9”, before the number is dialed.

• Prepend - add one or more digits at the beginning of the number, if this is required by the provider or gateway.

You can specify an ‘Outbound Caller ID’. 3CX will set the outbound caller ID although the telecom provider might disregard this outbound caller ID. See the event log for any errors if the outbound caller ID is not being shown on the call.

• Click “Save” to add the outbound rule.

ℹ️Now after the outbound rule is created it will be added to the bottom of the list, i.e. it has the least priority. If you want to increase the priority of an outbound rule you have to select it and click the “Move Up” button.
