To default the Call Me number in your dialer sessions, use the three dots in the top right of the application to select "Profile".

Once on your profile page, enter your phone number in the "call-me phone number" box. It is preferred that the number includes your country code prefix.

The format of the number can be free of dashes and special characters such as parenthesis. For example, acceptable variations of a phone number can be:
- 1-408-555-1234
- 14085551234
- +14085551234
- +1-408-555-1234
Click "Save" when you are done.
