How do I set my own caller ID in a 3CX phone system?

Instructions for setting individual caller IDs per extension in a 3CX phone system with sipgate trunking.

As a 3CX user in combination with sipgate trunking, you have the option of setting a caller ID number of your choice for each extension.

The caller ID number 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 to General ➔ Outgoing phone number. Enter the desired number here in E.164 format (49xxxxx / without plus sign or leading zeros).

If the caller ID number is not set here, then the Fallback sender number that you can find in the logged-in area of your sipgate account under Trunking will be displayed to the person being called.
