How do I set my own sender number in a 3CX phone system?

Guide to setting individual sender numbers per extension in a 3CX phone system with sipgate trunking.

As a 3CX user in conjunction with sipgate trunking, you have the option of setting a freely selectable caller ID for each extension.

The caller ID for the individual extensions can be set in a 3CX phone system as follows:

1

Select extension

First, select the extension to be configured in the 3CX system menu.

2

Enter phone number

Then go in the menu to General ➔ Outgoing caller ID. Enter the desired number here in E164 format (49xxxxx / without plus sign or leading zeros).

If the caller ID is not set here, the called party will see the Fallback sender number that you can find in the logged-in area of your sipgate account under Trunking .
