Calls are handled very simply. Since all phones are to be digital, the caller just dials the telephone number, and press the send or call button. Telephone numbers are either three digits for certain service numbers, or 12 digits for the standard telephone number.
One could select to have their number not show in CID – therefore showing as Anonymous, however the recipient can elect to send anonymous callers directly to voicemail. In addition, calling a service number, or a toll free number will not show up as anonymous, but instead – your telephone number will display.
