Your Profiles are not linked together on the site in the eyes of the caller/customer. Your Profiles can be completely different characters. However, when you are available on one Profile, you are available on all of your Enabled Profiles. You can have up to three (3) Enabled Profiles at a time.
When you receive a call from Psychics.com, you will receive a message with the Profile Number that is being called. If you listen to the complete message before pressing 1, you will be able to tell which Profile is being called. If you are at your computer, the active phone call display will pop up and list the Profile being called, so that you can press 1 to accept the call sooner.
