Plans: Needs a Harkbell phone number, so Essential, Pro, Business or a Powerhouse plan.

You keep the number on your window, your van and your clients' phones, and have it ring your agent instead. The forwarding is set on your own phone or with your phone company, not inside Harkbell.

  1. Get a Harkbell phone number first. The forwarding guide only fills in once your agent has a live number.
  2. Open Integrations, choose the Calling tab and open Phone number. Scroll to Keep your existing number.
  3. Under What is your number on? pick the option that matches your phone: a carrier, a landline, or a business phone system or app.
  4. Under Which calls should your agent answer? choose Every call or Only calls I miss or can't take.
  5. Copy the code shown under Code to dial, or follow the steps listed for a phone system, and use it from the phone your business number is on.
  6. Check it from a different phone using the Check it works note below the code.

What each option does

  • Every call sends all calls to the agent and your phone stops ringing.
  • Only calls I miss or can't take lets your phone ring first. Calls you do not answer within about 20 seconds, calls while you are on the line and, on most mobiles, calls when the phone is off go to the agent.
  • AT&T (or Cricket), T-Mobile (or Metro, Mint) and other mobile carriers use **21* then the agent's number then # for every call, or **004* then the number then # for the calls you miss; ##21# or ##004# turns it off. The panel shows the code with your agent's number already filled in.
  • Verizon mobile uses *72 followed by the ten-digit number for every call, or *71 followed by the number for calls you miss. *73 turns it off.
  • A landline in the US or Canada uses *72 plus the number for every call; dial it, wait for the agent to answer, then hang up. For “busy or no answer” forwarding on a landline, ask your phone company or look for call forwarding in your account online.
  • A business phone system or app (RingCentral, Google Voice, Grasshopper, Vonage and similar) has no code. Open its admin settings, find call forwarding, call handling or routing for the number, and forward to your agent's number.

Do not forward to yourself

The phone you forward from must not be the same phone you set as your transfer number, or a caller put through to a person comes straight back to the agent. Use your mobile as the transfer number. See transfer calls to a person.

Will callers see a different number?

No. Callers dial the number they always have. Calls the agent places itself, such as callbacks and reminders, show the agent's own number.

My phone keeps ringing instead of the agent answering. What now?

The forward did not take. Dial the code again, or ask your phone company to turn on call forwarding for the line. Some landlines need the code dialed twice within two minutes.

What happens to calls if Harkbell cannot answer?

If you have set a transfer number, your number is set up at the phone company to fall back to it when a call cannot reach the agent. With no transfer number the call rings unanswered, so it is worth setting one.
