What happens the first week after you install an AI receptionist

Forward the line first

The install is a star code, and the star code is where the first mistake happens.

On Verizon, by the carrier's own Call Forwarding FAQ, you dial *72 plus the 10 digit agent number to send every call to the agent right away. You dial *71 plus the number to send only the calls you do not answer or are busy on. You dial *73 to cancel. The same Verizon page says there is no monthly fee for forwarding on most plans, but forwarded calls are billed as minutes on plans without unlimited minutes.

Here is the catch. Verizon's FAQ page does not publish how many rings pass before a *71 forward kicks in, so the carrier gives you 0 published rings or seconds to plan around. So your voicemail and the agent are in a race, and the carrier will not say who wins. The only way to know is to call your own line from another phone and listen.

Check the caller ID

A fresh number can show as spam likely, and that is the carrier, not the agent.

The FCC explains on its caller ID authentication page that US carriers now sign caller ID under a framework called STIR/SHAKEN and check that signature down the line. A brand new number that the agent dials out from has no history. Until it is attested, it can show as unverified or spam likely on the customer's screen. Have the agent call your cell and your foreman's cell and look at what pops up.

If it says spam likely, that is a carrier process to work through, not a bug in the software. Ask the installer who handles attestation and when it clears.

Hold time costs money

The minute rate is real, but hold time is billed at the same rate as talk time.

Retell, a voice platform, prices its agents at $0.07 to $0.31 per minute on its public pricing page. Retell's pricing page breaks that into voice infrastructure at $0.055, text to speech at $0.015 or $0.040 with ElevenLabs, US telephony through Twilio at $0.015, and the language model from $0.0016 to $0.080 per minute depending on which model you pick. Retell also lists a phone number at $2.00 per month, 20 concurrent calls free and then $8.00 per concurrent call per month, and a knowledge base at $8.00 per month after the first 10 free.

Here is what the headline rate hides. Retell's pricing FAQ and its transfer call documentation say silence, hold and the warm transfer briefing are all billed at the full agent rate, 100 percent of the call, until the caller is connected to a human and the agent drops off. Retell's transfer doc lists 3 transfer modes, cold, warm and agentic warm, and says the ring timeout before a transfer counts as unanswered is set by the installer, not the platform. So a first week with many calls handed to a human costs more per call than the $0.07 to $0.31 headline suggests. Ask your installer what the timeout is and what the caller hears when nobody picks up.

Tell your crew first

The Department of Labor says tell staff before the install, not after.

The U.S. Department of Labor, in its AI Principles and Best Practices for employers, says "Employers should provide workers and their representatives advance notice and appropriate disclosure if they intend to use worker-impacting AI." The same document lists 8 principles, and one of them is establishing governance and human oversight. It also says training should reach "as broad a range of employees as possible throughout the enterprise, from executives and managers to supervisors and frontline workers."

It also says workers "should be informed of and have genuine input in the design, development, testing, training, use, and oversight of AI systems." In plain terms, your office manager should be on the test calls. She knows which caller is a repeat and which one is the inspector. The agent does not know that until someone tells it.

Test the calendar

Booking is where the agent can double you up.

We found no calendar vendor document worth citing, so this is a check to run, not a statistic. Have the agent book a job. Then have a second caller try the same slot, and have your office book on top of it by hand. If any of those go through, the agent is writing to a calendar it does not read, and a double booked Saturday loses a customer you just won.

The numbers that exist

Everything we could source for the first week, with who published it.

What stays human

The agent holds the empty seat. It does not delete the job.

BLS projects receptionist jobs falling only 2 percent over the next ten years, about 16,000 fewer out of 947,500, in its Occupational Outlook Handbook. BLS also projects about 105,100 openings a year over that same decade, most of them from people leaving and being replaced. That is a job being refilled over and over, not going away. The agent covers the seat you cannot fill and the overflow when the phone rings twice at once.

Judgment stays with people. The angry customer, the inspector, the sub asking about his check, those still go to a person. The agent's job is to make sure that person hears about it instead of finding a voicemail on Monday.

What we got wrong

The research pushed back on four things I believed.

I thought the BLS wage was a contractor front desk number. It is not, because BLS reports 42 percent of receptionists work in healthcare and social assistance. I thought hold time was free. Retell's docs say it is billed at the full rate until the human picks up.

I thought the voicemail race could be settled by reading the carrier page. Verizon does not publish the ring count, so you have to call the line yourself. And I would have written install first, tell staff later. The Department of Labor says the reverse, and I think they are right.

If you would rather not run these checks yourself, we install the phone agent and run every one of them before we hand it over. The consult is $199. Bring your carrier login and your calendar.
