Forwarding Phones
One number for all your phones, for life
GrandCentral makes life simpler by letting you control all your calls with one phone number. Choose which phones ring when your GrandCentral number is called or send calls directly to voicemail depending on who calls you. Personalization is easy, and there is no need to give different people different numbers or send out a new phone number if you change your job or move. Just update your GrandCentral forwarding settings.

Use phone forwarding to:

  • Control all your phone numbers and voicemail with one number
  • Have different phones ring for different callers
  • Update phone numbers without having to notify all your contacts
  • Choose to not have your GrandCentral number ring your home during the day
  • Have fun: Route calls from people you don't want to talk to directly to voicemail where they will hear a "special" voicemail greeting
