Quick answer: Nextiva has the cheaper entry seat: NEXT Core is US$15 a user a month billed annually, against US$20 for RingCentral’s RingEX Core. RingCentral has the cheaper AI call from 31 seconds to 2 minutes 30 seconds: its AI Receptionist (AIR) bills US$0.50 a minute in 30-second steps, against US$1.50 for each Nextiva XBert AI conversation. In our bill at annual prices (30 AI calls a user a month, 2 minutes 10 seconds each), Nextiva was US$27.50 lower at 5 users and RingCentral was lower at 25 (US$22.50) and 100 users (US$210). List prices as at 8 November 2026.
“RingCentral vs Nextiva” is a choice between two US cloud phone systems that both now sell an AI agent to answer calls. RingCentral sells RingEX (calls, video meetings and team chat), its AI Receptionist (AIR) as an add-on or standalone product, and RingCX as a separate contact centre. Nextiva sells the NEXT Core, Engage and Scale plans, its XBert AI agent for phone, SMS and web chat, and Nextiva Contact Center. We compare seats at 5, 25 and 100 users, the two AI meters, texting and The Campaign Registry (TCR), contact-centre add-ons, Salesforce and HubSpot, porting, contracts and uptime terms. Every vendor fact comes from ringcentral.com, support.ringcentral.com and nextiva.com, read on 8 November 2026, in US dollars unless marked A$.
Where Zian fits next to RingCentral and Nextiva
If the calls your phone system answers also need chasing afterwards, Zian AI is our pick for the AI layer, whichever of the two phone systems you choose: its agents answer inbound calls 24/7 as an AI receptionist that qualifies callers, books appointments, transfers calls and takes messages, then follow up by voice calls, SMS, email, WhatsApp, Instagram DMs and Facebook Messenger. Both AIR and XBert answer, book and text. On outbound calls they differ: RingCentral’s AIR pages describe none (its AIR Pro agents, which “Support inbound and outbound conversations”, are in early access), while Nextiva’s XBert AI answering service page says XBert “manages simultaneous inbound and outbound calls”, as at 8 November 2026.
Zian handles answering machines and voicemail on calls, works in 30+ languages with voice cloning supported, and connects to HubSpot, Salesforce, HighLevel and Zapier. SmartReach AI™ picks the message, channel and timing of each follow-up, and PrecisionPitch AI™ keeps split-testing scripts against real outcomes. Zian’s home page counts 50,769+ qualified sales appointments set.
The honest limits: Zian is in a partnership-application beta with no published prices, and each of its three listed plans, including Intel + Widgets (Free Forever), starts with a partnership application. zian.ai does not list a RingCentral or Nextiva integration, so settle how your calls reach Zian during that application. If you would rather have the work done for you, LeadsNow.ai is the done-for-you option: a managed, pay-per-result AI appointment-setting service that runs on Zian, answers leads in under 60 seconds, 24/7, and has set 50,769+ appointments.

Rows 1 and 2 are our picks when answered calls feed a sales pipeline; rows 3 and 4 are not ranked against each other. Disclosure: zian.ai publishes this page and Zian AI appears in it, ranked first; LeadsNow.ai is a sister business that runs on Zian. Method below.
| # | Option | What it is | AI that talks to callers | Entry price, as at 8 November 2026 |
|---|---|---|---|---|
| 1 | Zian AI (platform pick) | AI sales and reception agents platform, inbound and outbound | AI receptionist 24/7 plus follow-up by voice, SMS, email, WhatsApp, Instagram DMs and Facebook Messenger; 30+ languages | No published prices; partnership-application beta; Intel + Widgets listed as Free Forever |

| 3 | RingCentral | RingEX phone, meetings and chat; AIR add-on or standalone; RingCX contact centre | AIR: 100 minutes included, then US$0.50 a minute, billed in 30-second increments | RingEX Core US$20 a user a month annual (US$30 monthly); AIR from US$39 a month as an add-on |
| 4 | Nextiva | NEXT Core, Engage and Scale; XBert AI; Nextiva Contact Center | XBert AI: phone, SMS and web chat; US$99 a month for 100 conversations, then US$1.50 each | NEXT Core US$15 a user a month annual (US$23 monthly) |
RingCentral vs Nextiva pricing, plan by plan
These are US list prices from RingCentral’s RingEX pricing page and Nextiva’s pricing page, read on 8 November 2026. RingCentral’s page script prices its 1–5 and 6–100 user bands identically and leaves its 100+ band without a list price. Nextiva’s monthly prices load from the page’s toggle data, which we read.
| Plan | Billed annually, a user a month | Billed monthly | Calling, numbers and texts included | What the tier adds |
|---|---|---|---|---|
| RingEX Core | US$20 | US$30 | Unlimited domestic calling (US and Canada); a dedicated number for each user; 100 toll-free minutes; 25 SMS a user a month, pooled across the account | HD meetings for 300 participants, AI Virtual Assistant (AVA) included, on-demand call recording, AIR as an add-on |
| RingEX Advanced | US$25 | US$35 | 1,000 toll-free minutes; 100 SMS a user a month | CRM integrations, multiple sites, core reporting |
| RingEX Ultra | US$35 | US$45 | 10,000 toll-free minutes; 200 SMS a user a month | RingCentral Webinar, unlimited storage, device analytics |
| RingCentral AI Customer Engagement Bundle | Contact sales | Contact sales | As Ultra | AIR, AVA and AI Conversation Expert (ACE) included |
| Nextiva NEXT Core | US$15 | US$23 | Unlimited voice and video; 100 business texts a user; toll-free number an add-on | Team collaboration, skills-based routing, basic CRM and ticketing; 50 AI transcriptions, 50 AI summarisations, 50 AI Answer Assist conversations; XBert AI at US$1.50 a conversation |
| Nextiva NEXT Engage | US$25 | US$50 | 500 business texts a user; 1 toll-free number with 2,000 toll-free inbound minutes | Live chat and chatbot, 3 shared inboxes, single sign-on, virtual fax; 200 of each AI allowance |
| Nextiva NEXT Scale | US$75 | US$75 on the pricing toggle; “priced through sales” on Nextiva’s LLM info page | Unlimited business texts; 3 toll-free numbers with 10,000 toll-free inbound minutes | Directory sync, dedicated onboarding team, unlimited AI allowances, supervisor monitoring |
NEXT Core is US$5 a seat cheaper than RingEX Core on annual billing and US$7 cheaper on monthly. NEXT Engage and RingEX Advanced are both US$25 on annual billing, but Engage costs US$50 monthly against US$35. RingCentral says “Save up to 33% by paying annually”; Nextiva says “Save up to 50%”, which is Engage’s discount (Core’s badge says 35%).
Four limbs change the totals. Nextiva’s footnote says “Annual Small Business pricing applies to new customers with 1–100 employees signing a paid 12-month or longer minimum term agreement”, so a 100-seat buyer with more than 100 employees should ask for a quote. RingCentral’s 101st seat has no list price. RingCentral says “Unlimited phone calls are limited to US and CA markets only” and that taxes and fees such as the Federal Universal Service Recovery Fee and E911 Service Fee “may apply”. Nextiva’s pricing page says features marked Add-on “may involve setup, licensing, or usage fees”, and its pages disagree on CRM: the pricing comparison ticks Salesforce on all three plans, while its company information page lists “CRM integrations (Salesforce, HubSpot, etc.)” as an add-on on Core, Engage and Scale.
What RingCentral AIR and Nextiva XBert AI cost per call
The two AI receptionists use different meters, and the meter decides the bill more than the seat price does. RingCentral’s AIR pricing page says “Pay-as-you-go charges of $0.50 per minute apply if usage exceeds the total included minutes” and “Call time is rounded up and billed in 30-second increments.” Nextiva’s XBert page says “XBert AI pricing is $99 per month for 100 AI conversations. Additional conversations cost $1.50 each”, and defines a conversation as “a phone call longer than 30 seconds or an SMS/web-chat thread with three or more interactions”.
| RingCentral AIR (US) | Nextiva XBert AI | |
|---|---|---|
| Fixed monthly fee | From US$39 as a RingEX add-on; from US$49 standalone | US$99 (XBert page); Nextiva’s plan cards show only “XBert AI: $1.50 per conversation” |
| Included usage | 100 minutes a month | 100 conversations a month |
| Rate after that | US$0.50 a minute; minute bundles sold, unpriced on the page | US$1.50 a conversation |
| Billing unit | Every call rounded up to the next 30 seconds | Per conversation of any length; calls of 30 seconds or less do not count |
| Texting | AI SMS agent “Included in plan”, footnoted “Additional charges may apply” | SMS and web chat threads with 3+ interactions count as conversations |
| Trial and refunds | 14-day free trial on both AIR plans | 14-day free trial per Nextiva’s company information page, and the XBert page itself says “Try our AI Receptionist free for 14 days”, though that page’s structured data says “No free trial — live demo available”; 30-day money-back guarantee; “No long-term contracts” |
Nextiva’s pages leave one question open. The plan cards say “XBert AI: $1.50 per conversation”; the XBert page says “Add XBert to your Nextiva plan” at US$99 for 100. Our bill uses the US$99 package; charging US$1.50 from the first conversation would add US$51 a month to each Nextiva total below. Nextiva’s help-centre XBert Default Usage Rates article (updated 16 October 2026) also lists baseline rates of US$3.00 per phone number and per toll-free number, US$0.015 a minute for domestic outbound voice, US$0.025 a minute for inbound toll-free voice and US$1.50 per “AI Employee” session, with inbound voice and SMS “Included”; our bill assumes calls arrive on the plan’s existing local numbers, so none of these is added.
The Three-Minute Line: when Nextiva’s flat conversation beats RingCentral’s meter
The Three-Minute Line: at list price, an AI-answered call that lasts from 31 seconds to 2 minutes 30 seconds costs less on RingCentral AIR, costs the same from 2 minutes 31 seconds to 3 minutes, and costs less on Nextiva XBert AI once it runs past 3 minutes (or stays at 30 seconds or under). That holds because XBert charges a flat US$1.50 a conversation while AIR charges US$0.25 for every started half-minute, so a 3-minute call is US$1.50 on both.
The line compares calls beyond each allowance. On top of it, XBert’s US$99 package costs US$60 more than AIR’s US$39 add-on, Nextiva’s seats are cheaper, and calls of 30 seconds or less are free on XBert but bill US$0.25 on AIR. The table holds 25 users on the entry plans billed annually (US$375 on NEXT Core, US$500 on RingEX Core) and 750 AI calls a month, and changes only call length.
| Length of each AI call | AIR bills per call | RingCentral total | Nextiva total | Lower bill |
|---|---|---|---|---|
| 25 seconds | 0.5 minutes (US$0.25) | US$676.50 | US$474.00 | Nextiva, by US$202.50 |
| 1 minute | 1.0 minute (US$0.50) | US$864.00 | US$1,449.00 | RingCentral, by US$585.00 |
| 2 minutes 10 seconds | 2.5 minutes (US$1.25) | US$1,426.50 | US$1,449.00 | RingCentral, by US$22.50 |
| 2 minutes 45 seconds | 3.0 minutes (US$1.50) | US$1,614.00 | US$1,449.00 | Nextiva, by US$165.00 |
| 4 minutes | 4.0 minutes (US$2.00) | US$1,989.00 | US$1,449.00 | Nextiva, by US$540.00 |
| 6 minutes | 6.0 minutes (US$3.00) | US$2,739.00 | US$1,449.00 | Nextiva, by US$1,290.00 |
In the 25-second row XBert counts no conversations, so Nextiva’s bill is its seats plus the US$99 package.
What 5, 25 and 100 users cost a month: the worked bill
List prices only, computed by script on 8 November 2026, in US dollars a month, before taxes, regulatory fees, international calls, extra numbers, texting overage and TCR fees. Assumptions you can change: the entry plans (RingEX Core with the AIR add-on against NEXT Core with the XBert US$99 package); 30 AI-answered calls a user a month (150, 750 and 3,000 calls); every call lasting 2 minutes 10 seconds, which AIR bills as 2.5 minutes and XBert counts as one conversation; RingCentral’s unpriced AIR minute bundles not modelled.
| Team, billed annually | RingEX Core seats | AIR line | RingCentral total | NEXT Core seats | XBert AI line | Nextiva total | Lower bill |
|---|---|---|---|---|---|---|---|
| 5 users, 150 AI calls | US$100 | US$176.50 (375 min: US$39 + 275 × US$0.50) | US$276.50 | US$75 | US$174.00 (US$99 + 50 × US$1.50) | US$249.00 | Nextiva, by US$27.50 |
| 25 users, 750 AI calls | US$500 | US$926.50 (1,875 min: US$39 + 1,775 × US$0.50) | US$1,426.50 | US$375 | US$1,074.00 (US$99 + 650 × US$1.50) | US$1,449.00 | RingCentral, by US$22.50 |
| 100 users, 3,000 AI calls | US$2,000 | US$3,739.00 (7,500 min: US$39 + 7,400 × US$0.50) | US$5,739.00 | US$1,500 | US$4,449.00 (US$99 + 2,900 × US$1.50) | US$5,949.00 | RingCentral, by US$210.00 |
On monthly billing the same three teams cost US$326.50, US$1,676.50 and US$6,739.00 on RingCentral (US$30 seats), against US$289.00, US$1,649.00 and US$6,749.00 on Nextiva (US$23 seats). Nextiva is lower at 5 and 25 users, by US$37.50 and US$27.50, and RingCentral by US$10.00 at 100, because the monthly seat gap (US$7) is wider than the annual one (US$5).
On the middle plans, RingEX Advanced against NEXT Engage (both US$25 annual), the AI line decides alone: US$301.50 against US$299.00 at 5 users, US$1,551.50 against US$1,699.00 at 25, and US$6,239.00 against US$6,949.00 at 100. Monthly, Engage’s US$50 seat makes RingCentral lower at all three sizes: US$351.50 against US$424.00, US$1,801.50 against US$2,324.00, and US$7,239.00 against US$9,449.00. Without AI, NEXT Core is US$25, US$125 and US$500 a month cheaper than RingEX Core at the three sizes, billed annually.
RingEX Core adds HD meetings but no CRM integrations; NEXT Core adds 100 texts a user against 25 but no toll-free number. For the drivers behind any AI receptionist bill, see our breakdown of what an AI receptionist costs a small business.

What each AI receptionist does on a call
They differ most on channels and languages.
| Question | RingCentral AIR | Nextiva XBert AI |
|---|---|---|
| Channels | Voice, with an AI SMS agent and SMS follow-ups; WhatsApp and Shopify integrations marked “Coming soon” on the pricing page, though the release notes list AIR for Shopify in customer beta from 28 May 2026 | “Handles phone, chat, & text messages” |
| Booking | “Via calendar integrations or SMS links”: Google, Outlook, Calendly (the standalone plan card marks “WhatsApp, Calendly, and Shopify integrations” as coming soon) | XBert “books, confirms, and reschedules appointments in real time”; sends reminders |
| Languages | English (US, UK, Australian), French (Canadian and European), Spanish, Latin American Spanish, Italian, German and Portuguese on the pricing page; Dutch added 28 May 2026 and Japanese 23 September 2026 in the release notes | English, Spanish, French, German, Mandarin and Ukrainian, per Nextiva’s company information page; Russian added 22 October 2026 and Vietnamese 2 November 2026 in the Nextiva release notes |
| CRM | Salesforce, Zoho, HubSpot | Live at no cost: Google Calendar, Calendly, Cal.com, Zoho, Telegram, Housecall Pro; on request in 2–4 days at no cost: Salesforce, HubSpot, Pipedrive, GoHighLevel and 18 more |
| Your existing numbers | “Keep your number or get a new local number”; works with any phone “Via call forwarding or SIP integration” | Standalone or as an add-on; the XBert page says it goes live “with a dedicated phone number you can use to receive incoming calls”, and the AI answering service page says “XBert connects to your business phone system and existing phone number” |
| Outbound AI calling | We could not find an outbound skill for AIR; RingCentral’s AIR Pro page lists “Support inbound and outbound conversations” but AIR Pro is an early-access programme, and RingCentral’s 23 June 2026 release put AIR Pro “Autonomous Outreach” in RingCX in beta, with general availability planned for 2H 2026 | Sends reminders, confirmation texts, booking links and follow-up workflows; Nextiva’s XBert AI answering service page says XBert “manages simultaneous inbound and outbound calls without delays or dropped connections” |
The outbound cells are as at 8 November 2026: for AIR we searched its pricing page, AIR Pro page and release notes from May to September 2026; for XBert, the XBert, AI receptionist, AI voice agent and AI answering service pages, Nextiva’s company information page and llms.txt. If you pick AIR, our guide to RingCentral AI Receptionist setup, step by step walks through the configuration.
Contact-centre add-ons: RingCX vs Nextiva Contact Center
Both sell the contact centre as a separate per-agent product, so a team that needs diallers prices two lines.
| Tier | Price a user or agent a month | What it includes |
|---|---|---|
| RingCX Standard | US$65 annual, US$75 monthly | Voice and 20+ digital channels; ACD, IVR, skills-based routing; agent screen recording; AIR as an add-on |
| RingCX Professional | US$95 annual, US$110 monthly | AI Quality Management and AI Agent Assist included |
| RingCX Elite | US$145 annual, US$165 monthly | AI Supervisor Assist, AI Interaction Analytics and AI Workforce Management included |
| Nextiva Contact Center Essential | From US$75 (annual, per Nextiva’s company information page) | Voice and web chat, journey orchestration, smart call routing up to 5 agents, AI transcription and summaries billed by usage |
| Nextiva Contact Center Professional | Contact sales | Adds email and SMS, progressive, predictive and Quarterback dialling, PCI-DSS secure payment, real-time supervisor support, routing up to 10 agents |
| Nextiva Contact Center Premium | Contact sales | Workforce management included, unlimited channels and routing, advanced analytics, in-conversation payments |
RingCentral’s RingCX page lists “preview, progressive, predictive, and voice broadcast dialers”; its AI add-ons start at US$25 a user. Nextiva’s diallers start at Professional, which has no list price.
Integrations, texting and calling outside the US
RingCentral’s pricing FAQ claims “over 330+ integrations across 200+ companies”, with CRM integrations from RingEX Advanced. Nextiva’s company information page lists 37, including HubSpot, Salesforce, Zoho, Microsoft Teams, ServiceTitan and Epic.
Both require registration before business texting. RingCentral says “TCR Registration is required for SMS/MMS” and sells “Automated, high volume, or marketing SMS” separately as High Volume SMS from US$0.0119 a message. Nextiva’s plan tooltip says texting needs “Registration required.” Our guide to how long A2P 10DLC registration takes covers the stages and what delays them.
Location is the bigger split for Australian readers. Nextiva’s Master Terms say “Nextiva does not presently offer or support the Services to customers located in any countries other than the United States except where expressly agreed by Nextiva in writing.” RingCentral sells local plans: its Australian page lists RingEX Essentials at A$22.99 a user a month paid annually (A$25.99 monthly), before GST, for up to 49 users with 250 outbound minutes each, and AIR as a RingEX add-on at A$62 an account a month with 100 minutes, then A$0.80 a minute. That Australian AIR page lists English, French and Spanish only and marks appointment scheduling “(coming soon)”.
Porting your numbers to RingCentral or Nextiva
Nextiva’s Switch and Save page says “Keep your existing phone numbers. Porting included.” Its UCaaS terms say you will be “assigned a temporary telephone number until your transfer is completed”, that Nextiva “shall not be responsible for any delay in the port of your number and will not provide credit for any such delays”, and that it may “refuse to import a number” it lacks the infrastructure to support.
RingCentral’s numbering policy says “Customer must keep their existing service active in order to port a phone number to RingCentral”, that ports of more than 100 numbers from one provider account go through its Project Porting Department, and that requests are processed 8 am to 5 pm Pacific time, Monday to Friday. Completion “may depend on factors outside of RingCentral’s control”.
Leaving Nextiva, cancel only after the port completes: its cancellation policy says “If you cancel your Service prior to completion of the port, your Service will not work and your number may not be available for porting.”
Contracts, trials and cancelling
Both auto-renew. RingCentral’s Terms of Service renew “for successive periods of the same length as the Initial Term” unless notice is given at least 30 days before expiry, and a customer who ends the agreement for any reason other than RingCentral’s breach or a regulatory change must pay “all sums remaining unpaid for the Services for the remainder of the then-current Term”. Nextiva’s Master Terms also renew for the same length with 30 days’ notice, excluding “promotional or ‘free’ months”.
Nextiva’s pricing page says “Cancel anytime”, but its cancellation policy says that on a minimum commitment contract, “in addition to any disconnect fee, you will be responsible for all charges for the entirety of the then-current term”, and its 30-day money-back guarantee has six conditions, including no minimum commitment contract, no free device and no use of its digital-engagement or contact-centre services. Annual pricing requires a 12-month minimum term agreement, so ask whether your order counts as a minimum commitment contract before relying on the refund. XBert is sold with “No long-term contracts”.
RingEX’s 14-day trial supports “up to 20 phone lines” in its FAQ, but its disclaimer says “a maximum of five users and two desktop phones” and “SMS is not available for trial use.” Nextiva’s Switch and Save offer gives businesses under 200 employees “up to 12 months free”, with free months that “vary based on the remaining term of the customer’s current contract”, proof of that contract, and a minimum 12-month Core or Engage subscription.
Uptime SLA: what each vendor’s legal pages commit to
Both vendors advertise 99.999% uptime; only RingCentral’s pages call it an SLA. RingCentral’s pricing page says “RingCentral’s Cloud PBX has an SLA of 99.999% availability, which equates to just 78 seconds of downtime per quarter”, and marks “Less than 6 mins of annual downtime SLA (99.999% uptime)” as included on every RingEX plan. We could not find the SLA’s own terms (how downtime is measured, credits, exclusions) on RingCentral’s legal index, Terms of Service or RingEX Service Attachment, as at 8 November 2026; the Terms promise only “a commercially reasonable level of skill and care”.
Nextiva’s footer, network page and company information page say “99.999% Uptime” and “99.999% proven uptime”, but its legal pages point the other way. The Master Terms say “WE WILL NOT GIVE YOU CREDIT FOR ANY INTERRUPTION OF NEXTIVA SERVICES, INCLUDING INTERNATIONAL CALLING SERVICES”, and the UCaaS terms say the service is provided “on a best-efforts basis”. We found no service-level agreement with credits for Nextiva’s phone service on its legal page, Trust Center, status page, network page, sitemap or llms.txt, as at 8 November 2026. Whichever you choose, ask for the uptime commitment and its credit schedule in your order form; our explainer on what a reasonable enterprise uptime SLA for voice AI looks like sets out what to compare.
Pick RingCentral if, pick Nextiva if: the decision table
| Your situation | Lean towards | Why, from the vendors’ own pages |
|---|---|---|
| Phone seats only, no AI, US team | Nextiva | NEXT Core US$15 annual against RingEX Core US$20 |
| 25+ users billed annually, about 30 AI calls a user a month, mostly 31 seconds to 2 minutes 30 seconds | RingCentral | US$0.25 a started half-minute against US$1.50 a conversation |
| AI calls mostly over 3 minutes | Nextiva | Flat US$1.50 a conversation whatever the length |
| Lots of hang-ups and wrong numbers under 30 seconds | Nextiva | Calls of 30 seconds or less are not XBert conversations |
| AI that answers texts and web chat as well as calls | Nextiva | XBert handles phone, SMS and web chat in one package |
| Callers speak Italian, Portuguese, Dutch or Japanese | RingCentral | Listed for AIR; not on XBert’s list |
| Callers speak Mandarin, Ukrainian, Russian or Vietnamese | Nextiva | Listed for XBert; not on AIR’s list |
| Business outside the US, including Australia | RingCentral | Local plans and an Australian AIR add-on; Nextiva’s terms limit service to US customers unless agreed in writing |
| You want the uptime figure called an SLA | RingCentral, then get the terms in writing | Pricing page calls 99.999% an SLA; Nextiva’s terms rule out interruption credits |
| Diallers at a list price | RingCentral | RingCX from US$65 lists predictive dialling; Nextiva’s dialling starts at Professional, contact sales |
Who each option is wrong for
Zian is wrong for a buyer who needs a published price today or desk-phone seats for human staff. LeadsNow.ai is wrong for a team that wants to run its own scripts in-house; it is a managed service.
RingCentral is wrong for a seats-only US team chasing the lowest per-user price, and for receptionists that handle long calls. Nextiva is wrong for businesses outside the US, for teams of 25 or more on annual billing whose AI takes about 30 calls a user a month, mostly of 31 seconds to 2 minutes 30 seconds, and for buyers who need downtime credits from the standard online terms.
How we compared RingCentral and Nextiva
We read each vendor’s US pricing pages (including the data behind the billing toggles), product pages, legal pages, release notes and llms.txt on 8 November 2026, plus RingCentral’s Australian pricing. One rule applies to every row: a capability counts only where the vendor’s own page states it, read for “coming soon”, “early access”, add-on, plan and country limits. Where a vendor’s pages disagree, we printed both. “We could not find” means we searched the named pages for the feature and its synonyms, with a positive control on each saved file. Zian and LeadsNow.ai are described only from their own published claims. By editorial policy Zian ranks first as the platform pick and LeadsNow.ai second as the done-for-you pick; RingCentral and Nextiva are compared as phone systems, in no order of merit.
RingCentral vs Nextiva: frequently asked questions
Is RingCentral or Nextiva cheaper?
Nextiva is cheaper on seats and RingCentral is cheaper on AI calls from 31 seconds to 2 minutes 30 seconds. NEXT Core is US$15 a user a month billed annually against US$20 for RingEX Core (Nextiva pricing, RingCentral pricing). With 30 AI calls of 2 minutes 10 seconds a user, our bill at annual prices favoured Nextiva at 5 users and RingCentral at 25 and 100 (at monthly prices Nextiva was also lower at 25), as at 8 November 2026.
How much does Nextiva’s XBert AI cost?
Nextiva’s XBert page says US$99 a month for 100 AI conversations, then US$1.50 each, with no long-term contract and a 30-day money-back guarantee (Nextiva XBert). A conversation is a call longer than 30 seconds, or a text or chat thread with three or more interactions.
How much does RingCentral’s AI Receptionist cost?
In the US, AIR starts at US$39 a month as a RingEX add-on or US$49 standalone, each with 100 minutes, then US$0.50 a minute. RingCentral’s pricing page says “Call time is rounded up and billed in 30-second increments” (RingCentral AIR pricing).
What is the Three-Minute Line?
Our rule for the two AI meters: a call from 31 seconds to 2 minutes 30 seconds costs less on RingCentral AIR, one from 2 minutes 31 seconds to 3 minutes costs US$1.50 on both, and a longer call costs less on Nextiva XBert AI, which charges a flat US$1.50 a conversation and does not count calls of 30 seconds or less.
Does Nextiva work in Australia?
Not under its standard terms. Nextiva’s Master Terms say it “does not presently offer or support the Services to customers located in any countries other than the United States except where expressly agreed by Nextiva in writing” (Nextiva legal).

Do RingCentral and Nextiva guarantee 99.999% uptime?
RingCentral’s pricing page calls 99.999% availability an SLA; we could not find its credit terms on its legal pages as at 8 November 2026. Nextiva advertises 99.999% uptime, but its Master Terms say “WE WILL NOT GIVE YOU CREDIT FOR ANY INTERRUPTION OF NEXTIVA SERVICES” (Nextiva legal).
