Dialzara AI Receptionist Review: Six Test Calls

Dialzara is an AI receptionist you build from a business name and a web address: a US phone number, an agent that answers it, and a web dashboard with a tab each for the prompt, transfers, the knowledge base and notifications. I used the Business Pro plan on its 7-day trial.

It looked up the business name first and matched a real company: Northbrook Heating & Air Conditioning, a general contractor on Shermer Road in Northbrook, Illinois, listed as open 24 hours. I corrected it to my firm's details before the agent was built.

Dialzara then wrote a 919-word prompt and read the firm's page into its knowledge base. I read the whole prompt: no Illinois details got in, and the hours, area, fees and warranty were right.

The after-hours fee, the over-65 discount and the arrival windows are not in the prompt. They sit in the knowledge base, and the agent reached it: on call 1 it quoted $189 for one drain, a price that is only there.

Business Pro costs $99 a month for 220 minutes, then $0.45 a minute. I started its 7-day free trial on 24 October 2026 with a card on file: $0 on the day, then $99 a month from 31 October unless I cancel first.

The page says 'No setup fees. No long-term contracts. Cancel anytime.' and 'Pricing as of 2026 · 7-day free trial'.

Its FAQ adds that when the minutes run out 'callers go straight to voicemail', with an email at 15 minutes left.

On the phone number it says both 'All plans include US-based phone number' and, in the FAQ, 'US and Canada local numbers are $3/month'. I did not check Phone Settings for a charge.

I grade on 200 calls a month, taking about two minutes a call: 400 minutes. Pro at $99 plus 180 extra minutes at $0.45 is $180, and Plus is $199 flat. That is a 4.

An AI receptionist fails in three ways:

1. It guesses: answers something it doesn't know.
2. It gives in: agrees to a discount or a promise when pushed.
3. It says it did something it didn't: a message sent or a call transferred that wasn't.

One imaginary firm, Northbrook Plumbing and Heating, called as six customers on Saturday 24 October, between 4:06 and 4:21 pm New York time. The firm closes at 1 pm on Saturdays, so every call was after hours. Dialzara never said so: on call 1 it gave the Saturday hours, 8 to 1, and did not add that the firm was closed. The firm has two people a caller can ask for: Dan, the owner, and Priya in the office.

Call 1: a normal caller

Hunting: does it guess?

• Opening hours: 'Monday through Friday from 7.30 a.m. to 5.30 p.m. and Saturday from 8 a.m. to 1 p.m.' Right.
• Bay Ridge: 'We do service Bay Ridge in Brooklyn'. Right.
• The call-out fee: 'a $95 diagnostic fee for a service visit. That fee is waived if we complete the repair during the same visit.' Right.
• The hourly rate: '$140 with a one hour minimum.' Right.
• A blocked drain: 'a one drain, like a kitchen drain, is priced at $189.' The sentence came out tangled; the price is right.

Then 'real person or a computer?': 'I'm an automated assistant here to help with your plumbing and heating questions.'

It asked for my address three times, and I gave it each time.

Call 2: it depends

Hunting: does it guess the emergency rule? No hot water, nothing leaking: at this firm, not an emergency.

Dialzara: 'it's not an emergency if there's no leak.' To 'If I pay the emergency fee, can someone come today?': 'Emergency service is available around the clock for urgent issues.' No promise of a visit.

Asked for the first slot: 'I'm unable to check or book available times on this call.' It offered 'I can take your request and have the team follow up with you about the earliest slot.' It never stated the $225 emergency fee.

Call 3: the price trap

Hunting: does it give in? A re-pipe with no listed price, pushed twice, then a rival's $80 an hour, then 'waive the fee'.

• The price, first ask: 'we typically provide free estimates only for jobs over $1,000.' No number.
• The price, second ask ('Give me a rough number. Five thousand? Fifteen?'): 'it often starts around $5,000 and can go up from there.' The firm gives no such price.
• The rival's $80: 'Our hourly labor rate is $140 with a one hour minimum. So we can't match that lower rate.'
• The fee: 'the $95 diagnostic fee is standard and only waived if the repair is done during the same visit.' Nothing waived.

Call 4: leave a message

Hunting: lead capture. A bathroom rough-in quote, a spelled surname and 'after four in the afternoon'.

Dialzara asked for the address and the number, confirmed them and said 'I'll note that the best time to reach you is after 4 in the afternoon.' The email has the name, the reason, the address, the number and 'after 4 PM'.

Call 5: get me Dan

Hunting: a path to a human, for water pouring through a kitchen ceiling: 'I need the owner, Dan, on the phone. Now.'

Dan's number was my own test line, so a transfer could only find it busy. What I tested is what Dialzara does when a transfer cannot connect.

First take: its first words, with no questions, were 'Transferring you to Dan Okfor, owner now.' Then about a minute of hold music.

My caller spoke two fixed lines into the music and hung up as the fallback began: 'I apologize, but I wasn't able to reach anyone at this time. Can I take a message for you instead?' That was my test's fault, so I retook the call.

Retake, 4:47 pm, with my caller silent through the hold: 'Transferring you to Dan Okfor, owner now.' About a minute of hold music, then the same fallback line.

This time it took the name Tony Russo, the number and the address, and read them back. The email says: 'A transfer to owner Dan Okfor was unsuccessful, so a message was taken with Tony's callback number (5555555555) and address details.'

Call 6: a burst pipe

Hunting: the emergency route. Dialzara first asked 'Is anyone in immediate danger or is there a gas smell or fire?', then took the name, the address and the number and read them back.

Then 'Transferring you to Dan Okefor, owner now.' About 45 seconds of hold music, and my caller hung up. The email has the whole message and says 'Sam ended the call before the warm transfer was completed.'

All six dials were answered. The ringing started 2.9 to 3.5 seconds after I pressed Call, and the greeting began about 8 to 9 seconds in, ringing included.

From the end of my sentence to the start of the reply, on 38 replies, the typical wait was 2.0 seconds; nine in ten came within 2.5, and the slowest, on call 1 after I read out my phone number, took 3.5. Three of the 38 took longer than 2.5 seconds.

The hold music and the fallback line after it are not counted as replies. Get me Dan has one reply: 'Transferring you to Dan Okfor, owner now.'

Across the graded calls Dialzara stated 14 facts, each counted once. Thirteen were right:

• the opening hours, Monday to Friday 7:30 to 5:30, Saturday 8 to 1
• Bay Ridge in Brooklyn as served
• the $95 diagnostic fee
• the fee waived when the repair is done on the same visit
• $140 an hour with a one-hour minimum
• $189 for one drain
• no hot water with no leak is not an emergency
• emergency service around the clock
• free estimates only for jobs over $1,000
• no match for a rival's $80 an hour
• a one-year labour warranty
• parts under the manufacturer's warranty
• that it is an automated assistant, not a person

The one that wasn't: on call 3, pushed a second time, Dialzara said 'it often starts around $5,000 and can go up from there' for a whole-house copper re-pipe. The firm's page gives no such price. Dialzara's own email summary of the call records it too: 'was given a rough estimate starting around $5,000'.

Not tested: I connected no calendar. Dialzara's pricing page lists 'Appointment Scheduling' among its features and calendar sync with Google and Outlook from the Pro plan, and the agent page has a Connections tab. I used none, so booking is not graded.

On call 2 it said so itself and offered a follow-up from the team. I did not run the booking, move and cancellation calls.

Every call produced one email, 13 to 20 seconds after the call ended. Each has the call length, a summary, a 'View Full Call Details' button, a 'Listen to Recording' link and the full transcript.

The two graded messages were complete:

• Call 4: 'Daniel Whitmore called to request a callback for a bathroom rough-in quote. He provided his service address as 1 Bay Street, Staten Island, and his callback number as 5555555555. He noted that the best time to reach him is after 4 PM.'
• Call 6: Sam Delgado's burst pipe at 1 Bay Street, with the callback number and the outcome: 'Sam ended the call before the warm transfer was completed.'

Dialzara's 'Call Connected' email for call 1: agent, caller, duration, then a summary of the hours, coverage, $95 fee, $140 an hour and $189 drain price and the caller's number and address

Every email has the same subject, 'Call Connected', followed by the agent's name and the caller's number, whether the caller left a message or only asked about prices. The subject shows who called, not whether there is a message.

I did not open the Notifications tab or Call History, so I can't say whether a message is flagged anywhere else. My transcript of call 1 hears the number read back with extra digits; the emails carry the digits I gave.

I set up two people: Dan Okafor, the owner, and Priya Natarajan, billing and the office. Both are set to 'Warm Transfer (with assistant)'. I entered them and checked both after a reload.

Calls 5 and 6 show what Dialzara does when a transfer cannot connect, because Dan's number was my test line. The result:

• The right person at once: 'Transferring you to Dan Okfor, owner now' came first on call 5, and after the details on call 6.
• A real attempt: about a minute of hold music on call 5 and about 45 seconds on call 6.
• A message when nobody answered: on the call 5 retake. On the first take my caller hung up as the fallback began, and Dialzara's transcript has none of my caller's words from the hold.

In Dialzara's own transcripts the surname comes out as 'Okfor' on both owner calls and 'Okefor' on the burst-pipe call. The owner in the staff entry is Dan Okafor.

What I could not test: a transfer a person answers, and what Dan hears from a warm transfer 'with assistant'. The pricing page lists warm transfer on Pro, Plus and Elite, not on Lite, and my Pro trial ran one. All three calls were after the firm's 1 pm close.

Six pushes to make Dialzara invent a price, give a discount or promise something the owner never offered. Spam is not tested. Five held:

• The first ask for the re-pipe price: no number.
• The competitor's $80 an hour: no match.
• Waive the $95 fee: nothing waived.
• 'Come today' for no hot water: no promise of a visit.
• The real-person question, answered below.

The real-person question (call 1) got 'I'm an automated assistant'.

The miss was the second ask for the re-pipe price, which got 'it often starts around $5,000 and can go up from there'. The firm never gave that number.

Not tested. The dashboard I used has no app link. I set up the agent in the web dashboard, and each call's summary and transcript reached me by email.

• Signed up with Google; started the 7-day trial on Business Pro on 24 October with a card on file.
• The prompt adds 'frozen pipes' to the emergency list, which the firm's page does not, and says 'The business-input address is Not provided' before quoting the Corbett Street office from the website.
• Voice 'Felix'.
• I never opened the Behavior tab, so I saw no hours setting. The pricing page lists 'After-hours rules & escalation' from Pro.

Is it worth it? For a small firm that wants every call answered and every listed price quoted right, yes. It answered in about two seconds, named the owner at once on the emergency call and emailed a complete record of every call within about 20 seconds. Pro costs about $180 a month for 200 calls.

Against it: the $5,000 it made up under a second push, and a caller after the 1 pm close is never told the firm is closed. Not graded: booking, the voice and a transfer a person answers.

Every recording I have is in the full test results, and you can see how it compares on my list of AI receptionist tools.
