Comparing virtual receptionist options on price answers the wrong question. What a service can do on the call is set by the plan tier, not the category: of OfficeHQ’s 4 live-answering plan cards, only 2 list fee quoting and payments and only 1 lists appointment scheduling. Capability first, price second.
What people mean when they compare virtual receptionist options
“Virtual receptionist” is four products and one non-product wearing one label. The genuine shortlist:
- A human answering service. Off-site receptionists answer your diverted number. OfficeHQ, ReceptionHQ and Virtual Headquarters sell this in Australia, tiered from message-taking to diary management.
- An AI voice receptionist. Software answers, using speech recognition, a language model and a synthesised voice, usually built on a platform such as Vapi, Retell AI or Twilio whose documented limits become the product’s limits.
- An in-house part-timer or casual. A person on your payroll, covered in most offices by the Clerks-Private Sector Award 2020 (MA000002).
- A hybrid. AI takes first pass, humans take overflow and escalations.
- Voicemail plus a callback discipline. Not a purchase, and for a business missing a handful of calls a week inside business hours it is often the correct answer. No vendor will tell you so.
Most comparisons treat these as five price levels of one thing. They differ on what the person or system answering is allowed to do, and that decides the purchase. We worked the cost crossover in the AI receptionist versus virtual receptionist price comparison; this page is capability only, with no dollar figures in it.
What each option can actually do on the call
Rows are capabilities with a documented answer, not adjectives. The human column comes from OfficeHQ’s plan cards on its live call answering page and its after-hours answering page, both checked 12 September 2026; the AI column from Vapi’s documentation, as one platform’s worked example. A plan card lists what a tier advertises, not what a provider is incapable of, so where a capability is missing we name the card it is missing from.
| On the call, can it… | Human answering service | AI voice receptionist | In-house part-timer | Voicemail + callback |
|---|---|---|---|---|
| Answer at 2am | Yes, as a paid upgrade – every OfficeHQ card lists “24/7 service upgrade option” and the after-hours page footnotes its plans “Plus GST and after hours calls surcharge”. Without that upgrade OfficeHQ’s FAQ says it answers 8:00am-6:00pm on weekdays | Yes – the same configuration runs at 2am and 2pm, because there is no roster to cover | Not at ordinary rates. Ordinary hours under MA000002 are 7.00am-7.00pm Mon-Fri and 7.00am-12.30pm Sat (cl 13.3), so 2am is overtime or shiftwork | Records at 2am, responds never |
| Write a booking into your calendar | Diary tier only – appointment scheduling and diary management appear on OfficeHQ’s MyDiary card alone | Yes, if the calendar tool is wired up with write access – an integration, not a default | Yes | No |
| Quote a fee or take a card payment | MyAssistant tier up – “Quote fees & take payments” is absent from the MessageExpress and MyReceptionist cards | Only with PCI compliance enabled – Vapi documents the default of compliancePlan.pciEnabled as false | Yes | No |
| Hand the caller to a human mid-call, with context | Warm call transfers appear from the MyReceptionist card up; MessageExpress is sold as message taking and its card does not list transfers | Five traditional warm-transfer modes, which Vapi states “are supported on Twilio calls”, plus an assistant-based warm transfer documented separately – check the mode against your telephony provider | Yes, by walking over | No |
| Cope when it does not understand the caller | Asks again, in the caller’s words | Idle messages, then ends on a silence timeout (silence-timed-out). Vapi notes these “are automatically disabled during tool calls and warm transfers” | Asks again | Nothing to understand |
| Stay on a long, difficult call | Yes, billed by the minute or the call | Only if you raise the ceiling – Vapi’s maxDurationSeconds defaults to 600 seconds in a range of 10 to 43,200, so an unchanged assistant hangs up at ten minutes | Yes | Caller hangs up first |
Three of the six – writing a booking, quoting a fee or taking a payment, and a warm transfer with context – are off by default in both paid categories: on the human side they sit on a higher plan card, on the AI side behind a configuration switch or a telephony provider. OfficeHQ’s own after-hours page puts it best: “Depending on your plan, we can take messages, transfer selected calls, answer FAQs, submit leads into your CRM, take orders, process payments, schedule your appointments and more.” Depending on your plan is doing all the work there, and the same qualifier applies to AI.
The message-or-decision test
This rule settles most of these decisions in ten minutes and costs nothing to run. Take your last 20 missed calls and sort them into two piles: calls where a written message is a complete outcome, and calls where the caller needed a decision made while they were on the phone. A decision means a price, a time slot, a yes or no, a dispatch, a cancellation. If a message is a complete outcome, voicemail with a disciplined callback slot achieves it for nothing. If a decision was needed, a message-taking service returns a message, not a booking – a slower version of the problem you started with.
The piles map straight onto plan tiers, which is why this beats a price comparison. Pile one is satisfied by any provider’s entry tier. Pile two needs calendar write access, a fee schedule or a payment path: two tiers up on the human side, a configuration toggle on the AI side.
How many calls am I missing, and what does that change?
Volume does not choose the category; it chooses which constraint binds. This table names the constraint, because that is what you can check against your own call log.
| Missed calls a week | What actually binds | What fits | What to skip |
|---|---|---|---|
| Under 5, inside business hours, message is a complete outcome | Nothing – your callback discipline suffices | Voicemail with a fixed callback slot morning and afternoon | Any paid service – a monthly fee to avoid roughly 12.5 minutes a week of callbacks |
| 5-25, message-only, some after 7pm or on Saturday | Coverage hours | Entry message-taking plan with after-hours answering on, or AI | The diary and payments tiers you will never use |
| 5-25, but most callers want a slot, a price or a decision | Authority to act on the call | AI with calendar write access, or a human plan at the diary tier | Message-taking at any price |
| 25+, mostly routine, heavy evenings and weekends | The award span of ordinary hours | AI, or AI first with human overflow | In-house, for the reasons below |
| Enough to fill one contiguous three-hour block, with other work for the gaps | Minimum engagement, MA000002 clause 10.5 | In-house part-time – it beats everything else on judgement | Outsourcing the whole front line |
| Any volume, but calls include complaints, distress or licensed advice | Judgement and liability, not volume | Humans, or AI with a warm transfer path you have tested end to end | Unattended voicemail, and unattended AI |
The 12.5 minutes in row one is arithmetic you can redo, and it rests on one assumption you should see. OfficeHQ sizes its MyDiary packages at 50 included minutes for “about 20 calls 1-3 minutes long each month”, 100 for “about 40” and 150 for “about 60” (checked 12 September 2026) – a consistent 2.5 included minutes per call. That 2.5 is a billing allowance, not a measured handling time, and it sits above the midpoint of OfficeHQ’s own 1-to-3-minute range, so use it as a planning rate and nothing more: five missed calls a week is 12.5 minutes of callbacks at that rate, or 5 to 15 across the range. Work out what those calls are worth first; our breakdown of what a 7pm enquiry actually costs an Australian business shows how much of that figure is usually assumption.
Can I just hire someone part-time to answer the phone?
You can, and for some businesses you should. But the option is usually compared on hourly rate, and the constraints that actually bind are structural and published in the award text. The Clerks-Private Sector Award 2020 covers private sector employees “wholly or principally engaged in clerical work” (clause 4.1); another modern award may cover your industry instead, and award minimums are not what a person costs once superannuation, leave and insurance sit on top. This page is not employment-law advice: check your coverage and obligations with the Fair Work Ombudsman, which publishes the award at awards.fairwork.gov.au/MA000002.html (checked 12 September 2026).
- You cannot buy 40 minutes. Clause 10.5: “An employer must roster a part-time employee on any shift for a minimum of 3 consecutive hours.” Clause 11.4 applies the same floor to casuals, who must be paid “for a minimum of 3 hours’ work on each engagement even if they are rostered to work for fewer than 3 consecutive hours”.
- Three rostered hours is the equivalent of about 72 reception calls, and nobody answers 72. At OfficeHQ’s plan-sizing rate of 2.5 minutes, filling 180 minutes end to end would take 72 calls – but those are billed talk minutes, while the three hours are paid presence that a receptionist spends mostly off the phone. That gap is the finding: below roughly 72 calls in your busiest three hours you are not buying call answering, you are buying a person, which is right only when you have other work for them.
- Evenings and weekends are a different rate. Ordinary hours run 7.00am-7.00pm Monday to Friday and 7.00am-12.30pm Saturday (clause 13.3), and that spread “may be moved up to one hour forward or one hour back” by agreement (clause 13.4) – it does not stretch across an evening. Saturday ordinary hours attract 125% of the minimum hourly rate (clause 24.2); a public holiday attracts 250% with a minimum of 4 hours’ pay (clauses 24.4(a) and 24.4(d)). Anything outside the spread is overtime or shiftwork.
- The mobile-after-hours workaround is regulated. Clause 13A gives effect to the right to disconnect in section 333M of the Fair Work Act 2009: “unless it is unreasonable to do so, an employee may refuse to monitor, read or respond to contact, or attempted contact” from their employer outside working hours. Clause 13A.2 applied it from 26 August 2024 to employers that were not small business employers on that date, and from 26 August 2025 to employers that were small business employers on 26 August 2024.
None of this makes in-house a bad option. It makes it a staffing decision that happens to answer some phones – a different purchase from the one people think they are comparing.
Who each option is wrong for
A human answering service is wrong for you if you needed a booking and bought a message-taking plan, or if your calls spike at 9pm on Sunday and you are on a per-call rate with an after-hours surcharge on top.
An AI receptionist is wrong for you if many of your calls are complaints, distress or anything requiring a licence, or if nobody will own the configuration. Calendar write access, PCI, transfer destinations and the duration ceiling are switches somebody must set, and an unowned deployment runs on defaults nobody chose.
An in-house receptionist is wrong for you if you cannot fill three consecutive hours, or if your missed calls cluster outside 7am-7pm.
A hybrid is wrong for you if you have not tested the escalation path yourself, from a real mobile, at the hour it would fire. An untested handover is two products that both think the other one answered.
Voicemail is wrong for you the moment pile two stops being small, and immediately if your callers are ringing a competitor next. It is a discipline, not a product, and disciplines lapse in busy weeks – exactly the weeks the calls arrive.
Where Zian sits, and where it does not
Zian AI is an autonomous AI sales-agents platform, not a receptionist product, and stretching it to fit this query would not help you choose. Its Customer Support Agent runs 24/7 in 30+ languages and it has an Appointment Show-Specialist agent – adjacent ground – but answering your main line and taking a message is a receptionist product’s job. If that is your problem, buy one, and our comparison of an AI receptionist against an autonomous sales agent sets out the distinction.
The categories overlap at pile two. Once the caller needs a decision made, a follow-up run or an appointment protected, you have left reception and entered sales operations – the work Zian’s SmartReach AI(TM) and PrecisionPitch AI(TM) are built for. Zian is in partnership-application beta and publishes no pricing.
Frequently asked questions
How do I compare virtual receptionist options without comparing prices?
Compare what each option is permitted to do on the call: answer outside business hours, write to your calendar, quote a fee, take a payment, transfer to a human with context, and stay on a long call. All six are set by plan tier or configuration, so establish which you need before you look at a rate card.
Can a virtual receptionist book appointments in my calendar?
Only on a plan that includes it. OfficeHQ lists appointment scheduling and diary management on its MyDiary plan card and not on the MessageExpress, MyReceptionist or MyAssistant cards, on its live call answering page, checked 12 September 2026. On the AI side it is an integration you connect and grant write access to, not a default, so ask to see it write a real booking during the trial.
Can an AI receptionist take a credit card payment over the phone?
Only where the vendor supports it and it has been switched on. Vapi states that “the default value for compliancePlan.pciEnabled is false”, and that enabling it requires selecting PCI-compliant model, voice and transcriber options – see docs.vapi.ai/security-and-privacy/pci, checked 12 September 2026. Ask a vendor to show you the setting, not a claim.
What is the shortest shift I can roster a receptionist for?
Three consecutive hours, for most office roles. Clause 10.5 of the Clerks-Private Sector Award 2020 states that “an employer must roster a part-time employee on any shift for a minimum of 3 consecutive hours”, and clause 11.4 requires a casual to be paid for a minimum of 3 hours on each engagement even if rostered for fewer. The award is made by the Fair Work Commission and published by the Fair Work Ombudsman at awards.fairwork.gov.au/MA000002.html, checked 12 September 2026.
Can my existing receptionist just take the after-hours calls on her mobile?
Not as a standing arrangement. Clause 13A of the Clerks-Private Sector Award gives effect to the right to disconnect in section 333M of the Fair Work Act 2009, under which an employee may refuse to monitor, read or respond to contact outside working hours unless it is unreasonable to do so. Clause 13A.2 applied it from 26 August 2024 to employers that were not small business employers on that date, and from 26 August 2025 to employers that were small business employers on 26 August 2024. Get advice from the Fair Work Ombudsman, not a vendor.
Is voicemail ever the right answer?
Yes, under two conditions together: your missed calls are in single figures per week, and a written message is a complete outcome for nearly all of them. OfficeHQ sizes its MyDiary packages at 50 included minutes for about 20 calls it describes as 1 to 3 minutes long, an allowance of 2.5 minutes a call, so five missed calls a week is roughly 12.5 minutes of callbacks. What breaks it is competition: if the caller rings three businesses, the one that answers wins before your callback slot arrives.
Working out which one you need
Run the message-or-decision test on your last 20 missed calls, then read the threshold table against your own volume and hours. If the answer lands in pile two and the work is sales rather than reception, the Zian AI FAQ sets out what the agents handle, and you can Apply For Partnership.
