If you'd like to use the Ruby mobile app or online portal to spoof your caller ID to appear as your business number for outbound calls, Ruby must host your published number.* You can access the Choose Your Caller ID in the mobile app using the call button at the bottom center of the screen.

In the online portal, you can click on the phone icon in the upper right corner.
* If your business number is not hosted by Ruby, you can still use this feature to place outbound calls. You have the option to spoof calls to appear to come from your Ruby forwarding number, allowing you to hide your personal cell number from your clients. If anyone calls back to your Ruby forwarding number, their call will ring directly to your Ruby account.
** A note for our Canadian customers: In order to hide your cell phone number, the app dials a separate number in our phone system and connects the call through that number. The pool of numbers from which our system picks is based out of the US, so calls made through the app in Canada would be considered long distance even if you’re dialing your neighbor next door. We'd recommend double checking with your phone provider to see what your plan allows in regards to international calls before using this feature.
