Hello. Asking for some help with our small business, which includes just three people.

When people call our business line, I want the call to start with Employee A (who has a dedicated digital line and extension and has RingCentral installed on their desktop and cell phone.)

After about five rings, the call should then go to Employee B (who also has a dedicated digital line and extension and has Ring Central installed on their cell phone.)

After about five rings and still unanswered, the call would then go to Employee C's personal cell phone number.

I'm hoping not to have to add another user as Employee C would only serve as a backup on the rare occasion the other two are not available.

I'm appreciate of any and all suggestions.

Thank you.
