Australian AI receptionists

Local rivals that also answer with AI. The differences are pricing model (flat vs metered), whether booking is native or via a link, and whether the receptionist lives inside your business platform.

OneBookPlus vs Sophiie

sophiie.ai

One of Australia's most established AI receptionists, Australian-made, with its own CRM, website chatbot, email and SMS responses, and call recordings. Integrates with ServiceM8, Xero, Google Calendar, Outlook and Zapier.

Where Sophiie wins
Maturity and scale in the AU market (Sophiie reports 300k+ calls answered), plus audio call recordings, which OneBookPlus does not do, we provide text transcripts instead.
Where OneBookPlus differs
Sophiie does not publish pricing (quote/demo only); OneBookPlus publishes a flat price and books straight into the same calendar, CRM and invoicing you already run on, with no setup fee.

Published pricing: Not published, quote/demo only

OneBookPlus vs OfficeHQ

officehq.com.au

An established Australian answering service: live receptionists answering in Australia, plus a separate AI phone-answering plan with live human take-over, priced by included-call tiers.

Where OfficeHQ wins
A genuine Australian live-human receptionist team, if you want trained people (not AI) answering some or all calls, OfficeHQ staffs that and OneBookPlus does not.
Where OneBookPlus differs
OfficeHQ meters per call; OneBookPlus is a flat fee with no per-call charges, and the booking lands in your own calendar and CRM rather than a message relay.

Published pricing: MyAI from $20/mo (10 calls) to $365/mo (300 calls), ex GST; excess $1.50/call

OneBookPlus vs Hooroo

hooroo.ai/plans

An Australian AI receptionist whose signature is a natural Australian accent. Answers 24/7, blocks spam, and texts callers a link to your booking page so they schedule themselves.

Where Hooroo wins
The Australian-accent voice is its headline feature, and its per-minute plans start cheap for low call volumes.
Where OneBookPlus differs
Hooroo books via an SMS link to your external booking page; OneBookPlus books the appointment itself, directly into the calendar of the platform that also quotes and invoices the caller, with no per-minute meter.

Published pricing: Basic $75/mo (150 min) to Premium $249/mo (500 min), then per-minute overage

OneBookPlus vs Valory

valory.com.au/pricing

An Australian-built AI phone agent delivered as a managed, done-for-you service, Valory's team designs, deploys and tunes the agent for you, billed on metered minute and SMS tiers.

Where Valory wins
The done-for-you model: if you want a specialist team to build and maintain a custom voice agent rather than configuring one yourself, Valory sells exactly that.
Where OneBookPlus differs
OneBookPlus is self-serve with no setup fee and no per-minute metering, and it is already wired into your bookings, contacts and invoices because it lives inside the same platform.

Published pricing: Intro $149/mo (100 min) to Enterprise from $1,299/mo; setup from $990

OneBookPlus vs Johnni

johnni.ai

A Brisbane-built AI voice receptionist purpose-tuned for trades, Australian-accent voices, call recordings and summaries, and integrations with ServiceM8, Simpro, AroFlo, Xero and more.

Where Johnni wins
Trade-specific tuning and a long integration list into existing trade job-management tools, plus audio recordings and 40+ languages.
Where OneBookPlus differs
Johnni books out into other platforms; OneBookPlus books into its own, the call becomes a booking, a contact and later an invoice in one system, at an effective $104/mo ($79/mo + AI Companion $25/mo) against Johnni's published price below, with the difference buying the whole business platform underneath rather than the phone agent alone.

Published pricing: From $99/mo, 30-day free trial

US and international answering services

AI and live-human answering desks built for North-American callers. Strong products, but check Australian numbers, data residency and time-zone fit before buying.

OneBookPlus vs Smith.ai

smith.ai/pricing

A mature US answering desk: AI answers with optional handoff to 500+ live human agents, plus a 100%-human plan. Books via Calendly with native HubSpot, Salesforce and Clio integrations.

Where Smith.ai wins
The AI-plus-live-human hybrid and a deep professional-services integration catalogue, strong for legal and consulting firms already in those tools. English and Spanish only.
Where OneBookPlus differs
Smith.ai has no published Australian numbers or AU data residency and bills per call; OneBookPlus includes a free AU number, AWS Sydney hosting, 10+ languages and a flat fee.

Published pricing: AI Receptionist from US$95/mo; overage US$2.40/call; live handoff US$3/call

OneBookPlus vs Ruby

ruby.com/plans-and-pricing

Friendly live US-based humans answer your calls; Ruby's AI (CallNav) assists those people rather than answering first. Chat plans are sold separately.

Where Ruby wins
Every call is answered by a real, trained person, the strongest option here if a human voice on every call is non-negotiable and your callers are in North America.
Where OneBookPlus differs
Ruby's minutes round up and include after-call work, so busy months are hard to predict; OneBookPlus answers with AI on a flat fee, books the job itself, and pushes live calls to your own mobile when you want to take over.

Published pricing: Per-minute buckets: US$250/mo (50 min) to US$1,725/mo (500 min)

OneBookPlus vs Goodcall

goodcall.com/pricing

A mature, US-built AI phone agent with unlimited minutes and tokens, priced per agent by unique monthly customers, with serious security credentials.

Where Goodcall wins
Unlimited minutes on every tier is a genuinely simple model for high-volume lines, and its security posture is well documented.
Where OneBookPlus differs
Goodcall is a standalone agent you wire into other tools; OneBookPlus books natively into its own calendar and CRM, includes a free Australian number, and is hosted in Australia.

Published pricing: US$79 to US$249/mo per agent by unique customers; overage US$0.50/customer

OneBookPlus vs Rosie

heyrosie.com/pricing

A tidy, low-entry US AI phone-answering service, English/Spanish, message-taking on the entry tier, with appointment booking and call transfers unlocked on higher tiers.

Where Rosie wins
The lowest published entry price in this roundup for pure message-taking, with a 7-day free trial.
Where OneBookPlus differs
Booking costs extra minutes and a higher tier at Rosie; OneBookPlus books on its base price, answers SMS as well as calls, speaks 10+ languages, and runs on an Australian number.

Published pricing: US$49/mo (250 min, no booking) to US$299/mo; booking from the US$149 tier

OneBookPlus vs Slang.ai

slang.ai/pricing-au

A polished AI 'Superhost' built only for restaurants, unlimited concurrent calls, reservations into OpenTable, SevenRooms and Tripleseat.

Where Slang.ai wins
Deep restaurant-reservation integrations and hospitality-specific polish; if you run a high-volume venue on OpenTable, it is purpose-built for you.
Where OneBookPlus differs
Slang.ai serves restaurants only and publishes no Australian phone numbers; OneBookPlus answers for any business type, books any appointment, and costs a fraction of A$399/location.

Published pricing: A$399/mo per location (Premium A$599)

OneBookPlus vs Dialpad

dialpad.com/ai-agent

A mature multi-seat business phone system (UCaaS) with bundled AI transcription and sentiment. Its built-in 'virtual receptionist' is IVR routing; answering-that-books lives in a separate, quote-only AI Agents product.

Where Dialpad wins
If you need a full enterprise phone system, per-seat lines, genuine AU numbers and porting, SOC 2 / ISO 27001, live human teams, Dialpad is the deeper telephony platform.
Where OneBookPlus differs
OneBookPlus is a finished receptionist, not a phone system: one flat price, logins included by plan (1 / 3 / 5 / 10 by tier) rather than licensed per seat, no quote-only add-on, and the answered call becomes a booking in your own business.

Published pricing: From ~US$15/user/mo; AI Agents product is quote-only

OneBookPlus vs Synthflow & Bland

synthflow.ai/pricing

No-code toolkits for building your own AI voice agent, powerful and flexible, with per-minute pricing and your choice of telephony. You wire booking and CRM yourself (Cal.com, HubSpot, Zapier).

Where Synthflow & Bland wins
Total control: custom flows, custom voices, your own integrations. The right choice for teams with an engineer who wants to own the agent end to end.
Where OneBookPlus differs
OneBookPlus is the buy in build-vs-buy: a finished receptionist that answers and books out of the box on a flat Australian price, with no per-minute meter and nothing to assemble.

Published pricing: Synthflow ~US$0.11 to US$0.24/min all-in; Bland US$0.14/min or from US$299/mo

Call tracking and attribution

These tools measure the calls a human still answers. If your problem is missed calls rather than attribution, a receptionist and a tracker are different purchases, some businesses run both.

OneBookPlus vs WildJar

wildjar.com/pricing

Australia's call-tracking and analytics leader, dynamic number insertion, call recording and keyword-level attribution for marketers who need to know which campaign made the phone ring.

Where WildJar wins
Attribution depth. If your question is 'which ad drove this call?', WildJar answers it better than OneBookPlus, which does per-number campaign tagging and UTM passthrough only.
Where OneBookPlus differs
WildJar measures calls a human still has to answer; OneBookPlus answers them, 24/7, in an Australian voice, and books the job. Different jobs; some businesses run both.

Published pricing: From $89/mo + usage (calls $0.10/min, numbers $15 each)

OneBookPlus vs Delacon

delacon.io/au

An Australian call-tracking, call-management and speech-analytics platform: it tracks, records, analyses and routes the calls your team answers.

Where Delacon wins
Speech analytics and enterprise call-management depth, with Australian operations and support.
Where OneBookPlus differs
Delacon does not answer the phone; OneBookPlus does, then screens spam, texts a transcript, and books the caller into your calendar, on a published flat price rather than a custom quote.

Published pricing: Not published, quote only

OneBookPlus vs CallRail

callrail.com/voice-assist

Deep US marketing attribution, number pools, keyword attribution, form tracking, with AI answering bolted on as a separate Voice Assist add-on.

Where CallRail wins
Marketing attribution for agencies and multi-channel advertisers; its reporting is far deeper than OneBookPlus's per-number tagging.
Where OneBookPlus differs
Getting tracking plus answering at CallRail stacks a metered plan and a separate add-on; OneBookPlus bundles AI answering, booking and a free Australian number into one flat fee.

Published pricing: Lead Tracking from US$50/mo metered; Voice Assist add-on ~US$95/mo

OneBookPlus vs CallTrackingMetrics

ctm.com/plans-pricing

A US attribution and contact-centre stack. Its VoiceAI agent genuinely answers, qualifies and books, but it effectively lives on the Sales Engage tier with metered minutes, and phone numbers are bought separately.

Where CallTrackingMetrics wins
A full contact-centre feature set (queues, softphone, agent routing) on top of attribution, the right shape for real sales teams with agents.
Where OneBookPlus differs
OneBookPlus packages AI answering, spam screening, booking and a free AU number into one flat plan, no tier ladder, no per-minute meter, no separate number purchase.

Published pricing: US plans US$79 to US$329/mo; VoiceAI effectively on the $329 tier, then $0.12/min

Choosing a phone-answering service

Why is this one roundup instead of separate comparison pages?

We previously published an individual comparison page for each of these 16 services. Reader behaviour told us that was the wrong shape: someone choosing a phone-answering service compares the whole market at once, not one vendor at a time. This roundup carries the same per-vendor pricing citations as the old pages, each figure links to the vendor's own published page, in one place you can read end to end. The old URLs redirect here.

What exactly is the OneBookPlus AI Receptionist and what does it cost?

It is a paid app inside OneBookPlus: AI answers your calls and SMS 24/7 with natural neural voices in English plus 10+ languages, screens spam, books and reschedules straight into your OneBookPlus calendar, captures the caller as a CRM contact, and can hand a live call to your mobile via a push notification. It costs a flat $79/mo inc. GST (requires AI Companion at $25/mo, included free on the Growth plan), includes a free Australian phone number, and is hosted in AWS Sydney. There is no per-minute or per-call metering; extra conversations are simple top-ups.

When should I pick one of these competitors instead?

Pick a live-human service (Ruby, OfficeHQ's human plans, Smith.ai's hybrid) if a real person on every call is non-negotiable. Pick Dialpad if you need a full multi-seat enterprise phone system. Pick Synthflow or Bland if you have an engineer who wants to build a custom voice agent. Pick WildJar, Delacon, CallRail or CallTrackingMetrics if your problem is marketing attribution rather than missed calls, and note that call recording (audio) is something several of these offer and OneBookPlus deliberately does not; we provide text transcripts with sentiment instead.

Can I keep my existing business number, or do I have to advertise a new one?

You can keep it. A free Australian local number comes with the subscription, and you can port your existing business number across instead, or add a 1800 toll-free number (toll-free carries a small monthly carrier fee, shown before you claim the number). Porting is a carrier process, so allow time for it and keep the old service running until the port completes. Several of the services in this roundup take the same approach, so if number portability matters, confirm it with each vendor before you sign.

Do callers know they are talking to an AI, and are the calls recorded?

Yes to the first. Automated-assistant disclosure is part of the greeting, so callers are told before the conversation starts, and where recording is enabled the consent notice is in the greeting too. On the second: OneBookPlus does not store audio recordings, you get a text transcript with sentiment and the outcome of the call. Several rivals here (Sophiie and Johnni among them) do keep audio, so if you need to play a call back for a dispute or for coaching, that is a real reason to choose one of them. This is general information, not legal advice, call-recording rules vary by state and it is worth checking your own obligations.

Where do these AI receptionist prices come from, and how fresh are they?

Every competitor price is quoted 'as published' with a link to the vendor's own pricing page, and was last verified on the review date shown at the bottom of this page. Vendor pricing changes frequently, always check the vendor's site before making a decision.
