JustCall vs OpenPhone 2026: Which Solution Is Right for Your Team?
TL;DR: JustCall vs OpenPhone (Quo)
- 01Choose JustCall if outbound volume is the point of the tool. Power dialing, campaign messaging, and AI call scoring all live here, from $29 per user/month billed annually on Team, with a two license minimum.
- 02Choose OpenPhone (Quo) if you want a shared business number a five person team can run without a setup project. Starter is $15 per user/month billed annually, and Sona, Quo's AI agent, is included on every plan.
- 03Consider CloudTalk if neither trade-off fits: IVR and skill based routing sit on the entry plan at $25 per user/month, Power Dialer comes with Expert, and Parallel Dialer, AI Conversation Intelligence, and AI Voice Agents are add-ons you switch on when you need them.
Neither platform wins this comparison outright:
JustCall and OpenPhone (Quo) both run business calling, and they're built for different jobs. JustCall is the automation heavy option, and Quo is the simple one. The right pick follows your call volume and team shape, not a universal ranking.
Both platforms handle business calling competently, and they're built for different sized problems. JustCall consolidates outbound sales work: dialers, bulk SMS and WhatsApp campaigns, local numbers in 70+ countries, and an AI voice agent you can attach to any plan. Quo consolidates small team calling: one shared number, unlimited calling and messaging to US and Canadian numbers under a fair usage policy, voicemail transcripts, and an AI agent that picks up when nobody can.
OpenPhone rebranded to Quo on 23 September 2025, announced on the company's own blog the same day it closed $105 million in growth financing1. It was direct about what didn't change: same app, same numbers, new name. The transition is still partly in flight, and you'll see the OpenPhone name inside the product and on some pages, which is why we write "OpenPhone (Quo)" throughout.

JustCall vs. OpenPhone (Quo): Core Strengths of Each Platform
Both products put a business phone on your laptop and your phone, and that's roughly where the overlap stops. JustCall is built for teams whose day is measured in calls placed and messages sent. Quo is built for a handful of people sharing one number and handling each conversation well.
Where JustCall Shines
- Dialers for throughputPower dialing from Pro; dynamic and predictive dialing (up to 10 lines) in the SalesPro line. Reps stop dialing by hand.
- Campaign messaging at scaleBulk SMS from Pro, WhatsApp in the messaging suite, 1,000 bundled text segments per user on Pro and above.
- AI on top of the callVoice agent add-on on every tier, first 100 minutes free, published volume discounts down to $0.15 per minute.
- Numbers in 70+ countriesLocal numbers on every plan, so distributed reps dial with local presence.
- A signed BAA is availableSOC 2 Type 2, ISO 27001:2022, and GDPR, plus a HIPAA BAA on the Business tier. JustCall signs its own template only.
Where OpenPhone (Quo) Shines
- Lower entry price$15 per user/month billed annually, against $29 and a two license minimum on JustCall's cheapest plan.
- No metered calling in North AmericaUnlimited calls and messages to US and Canadian numbers on every plan, under fair usage.
- Sona on every planThe AI agent ships on all three tiers with 1,000 credits (10 calls) a month included.
- Shared numbers without an upgradeStarter shares a number with up to 10 paid users; Business and Scale make it unlimited.
- Little to set up, easy to leaveOne new or ported number per user, and self service cancellation with numbers held 60 days.
At a Glance: JustCall vs. OpenPhone (Quo), Key Differences
Find the dimension that decides it for your team, then jump to that section for the detail behind the cell. We've swapped the usual "winner" column for "best suited for", because on nearly every row the answer depends on the shape of your team rather than on product quality.
| Dimension | JustCall | OpenPhone (Quo) | Best suited for |
|---|---|---|---|
| Entry price (per user/month, annual) | $29, two license minimum | $15 ($19 monthly) | Teams counting seats month to month |
| Auto and predictive dialing | Power dialer on Pro; predictive in SalesPro only | Not listed at any tier | Outbound teams working long lists |
| Call and text limits | 1,000 outbound and 1,000 inbound minutes per user, pooled; 500 to 1,000 SMS segments | Unlimited to US and Canada, fair usage; international is an add-on | Teams that don't want to meter minutes |
| AI depth | Voice agent add-on on any tier; AI scoring and sentiment on Pro Plus | Sona included on every plan, 10 calls a month before credit packs | Teams that want AI answering, not just summarizing |
| Video calling | Not offered | Not offered | Teams that want voice and video from one vendor |
| Phone menus and routing | IVR from Team; intelligent routing from Pro | Phone menus from Business, multi level since the rebrand | Support teams routing by skill, language or hours |
| HIPAA and BAA | Business tier, custom priced, JustCall's template only | "Talk to sales" item | Healthcare, legal and financial teams |
| International coverage | Local numbers in 70+ countries on every plan | US and Canada included; international billed per minute or message | Teams calling outside North America |
| Phone support | Business and SalesPro | Scale only, Mon to Fri, 8am to 5pm PT | Teams that want a human on the line |

The rows above simplify a lot, so the sections that follow unpack the ones that decide most deals.
JustCall Features vs. OpenPhone (Quo) Features
The clearest way to read JustCall vs OpenPhone features is to ask what each platform assumes you already have. JustCall assumes a sales floor's worth of dialing, messaging, and coaching work. Quo assumes you'd rather have one number and almost nothing to configure.
JustCall Features
JustCall packs a sales floor's worth of tooling into one app: dialing modes, campaign messaging, call menus, analytics, and an AI layer that scores and summarizes what happened. The catch is that it's spread across four priced tiers plus two quote priced ones, so the plan you land on decides how much of it you get.
| What JustCall Does Well | Where JustCall Falls Short |
|---|---|
| Dialing modes for volume. Power dialing on Pro, dynamic and predictive dialing (up to 10 lines) in SalesPro. | The real floor is $58, not $29. Team carries a two license minimum before any add-on. |
| Campaign messaging at scale. Bulk SMS from Pro, WhatsApp in the messaging suite, 1,000 bundled segments per user on Pro and above. | The dialers aren't where buyers expect. Power dialing needs Pro at $49; predictive dialing isn't in the standard ladder at all. |
| Routing from the entry plan. IVR and call menus on Team; intelligent routing and queue callback on Pro. | Bundled minutes have carve outs. Inbound only covers routes under $0.02 a minute and excludes toll free, UK and Australian mobiles, international calls, and call forwards. |
| AI that reviews the call. Pro Plus adds an AI notetaker, call scoring, script compliance, sentiment analysis, and real time agent assist. | Compliance sits behind a quote. The HIPAA BAA is on the Business tier, custom priced with a 10 license minimum, and JustCall won't sign your template. |
| Bundled minutes in four regions. 1,000 outbound and 1,000 inbound minutes per user, pooled, covering the US and Canada plus UK and Australian landlines. |
OpenPhone (Quo) Features
Quo is a mobile first phone system for small teams that want a shared business number and not much to administer. Since the rebrand it also ships Sona, an AI agent that answers and handles calls, on every plan rather than reserving it for the top tier. Most team features and most of the CRM depth start on the middle plan.
| What OpenPhone (Quo) Does Well | Where OpenPhone (Quo) Falls Short |
|---|---|
| Calling and texting that isn't metered. Unlimited calls and messages to US and Canadian numbers on every plan. | No dialer at any tier. Auto, power, and predictive dialing don't appear on Quo's published comparison, so list work stays manual. |
| Sona from the entry plan. 1,000 credits a month, which is 10 handled calls, with packs at $25, $49, $99, and $199 above that. | No video calling and no real time queue monitoring. Neither is listed, which rules Quo out as a contact center replacement. |
| One number, properly shared. Starter covers up to 10 paid users; Business and Scale add unlimited sharing, group calling, transfers, and ring order. | The product starts on Business. Phone menus, automatic recording, AI summaries on all calls, analytics, HubSpot, and Salesforce all begin at $23 per user/month. |
| A number per user included. New or ported, with extras at $5 a month. | Phone support is a Scale feature. Email is on every plan and chat starts on Business, but a phone line means $35 per user/month, Mon to Fri, 8am to 5pm PT. |
| Developer access on the cheapest plan. Quo API, webhooks, and a ChatGPT and Claude MCP connector, no upgrade needed. |
Feature-by-Feature Comparison
| Feature | JustCall | OpenPhone (Quo) | CloudTalk |
|---|---|---|---|
| Auto and predictive dialer | Power dialer on Pro; predictive (10 lines) in SalesPro | Not listed | Power Dialer included on Expert, add-on below it; Parallel Dialer is an add-on on any plan |
| Bulk SMS and WhatsApp | Bulk SMS from Pro; WhatsApp in the messaging suite | SMS to US and Canada included; automated SMS $0.01 each | International SMS and MMS, two way WhatsApp; bulk SMS isn't supported |
| Video calling | Not offered | Not offered | Not offered |
| AI voice agent and summaries | Voice agent add-on on any tier; AI analysis set on Pro Plus | Sona included, 10 calls a month; all call summaries from Business | The AI Voice Agent and AI Conversation Intelligence are always add-ons |
| Advanced IVR | IVR from Team; intelligent routing from Pro | Phone menus from Business, multi level since the rebrand | IVR, skill and smart condition based routing from Starter, plus a visual call flow builder |
| Real time queue monitoring | Real time agent assist on Pro Plus | Not listed | Live call monitoring, agent status reporting, and Wallboards |
| HIPAA and BAA | Business tier, JustCall's own template | "Talk to sales" | HIPAA tooling with BAA support and PHI handling on recordings and transcripts |
| Phone support | Business and SalesPro | Scale only, business hours PT | Chat, email, and phone support |
Feature parity is closer than it first looks. What separates the two is which tier you have to buy to get the row you care about, which is where total cost comes in.
Scaling Beyond a Small Team: JustCall vs. OpenPhone (Quo)
You rarely notice you've outgrown a small team phone system until the symptoms pile up: a supervisor who can't see the queue, a rep copying numbers into a dialer by hand, a routing rule nobody can build, and a ticket that sits over the weekend because phone support is two tiers up. Both products have a version of that ceiling, in different places. Quo's is structural: no dialer, no queue monitoring, phone menus on the middle plan. JustCall's is commercial: the capability exists, and reaching it means Pro Plus, SalesPro, or a custom quote.
| Dimension | JustCall | OpenPhone (Quo) | CloudTalk |
|---|---|---|---|
| Auto dialer availability | Power dialer on Pro; predictive only in quote priced SalesPro | Not listed at any tier | Power Dialer included on Expert, add-on below; Parallel Dialer an add-on on any plan |
| Advanced IVR and call flow building | IVR from Team; intelligent routing from Pro | Phone menus from Business, multi level since the rebrand | Visual call flow builder plus IVR and skill based routing from Starter |
| Real time queue monitoring | Real time agent assist on Pro Plus | Not listed | Live call monitoring, agent status reporting, Wallboards |
| Workforce management tooling | Not published as a plan feature | Not published as a plan feature | No scheduling module; supervision runs on Wallboards, live monitoring, and group reporting |
| Where it starts to strain | A price ceiling, not a capability one: full AI and compliance need Pro Plus, SalesPro, or a quote | Our read of the published gating: Starter's shared number caps at 10 paid users, phone support needs Scale, and there's no dialer | Contact center shaped from Starter up, with the heavier dialers sold as add-ons |
Total Cost of Ownership: JustCall vs. OpenPhone (Quo)
Sticker price and running cost are different numbers here, because on both platforms the AI and automation growing teams actually want sit above the entry plan. On JustCall, the full AI set is a Pro Plus line item and the voice agent bills per minute on top. On Quo, Sona is included but rationed at 10 calls a month, so real usage means a credit pack, and phone support means the top plan. Price the tier you'll be on in six months, not the one you sign up for today.
| Cost dimension | JustCall | OpenPhone (Quo) | CloudTalk |
|---|---|---|---|
| Entry price (per user/month, annual) | $29, two license minimum | $15 ($19 monthly) | $25 |
| Tier needed for full AI | Pro Plus at $89, plus per minute voice agent | Sona included, then credit packs $25 to $199; all call summaries need Business at $23 | Always add-ons: AI Conversation Intelligence $9 per user/month, AI Voice Agents from $99 a month for 200 minutes |
| Tier needed for phone support | Business or SalesPro, both quote priced | Scale at $35 | Chat, email, and phone support |
| Extra phone numbers | Two free per account | $5 per number per month | Local numbers in 160+ countries, porting supported |
| Five people who want AI | Pro Plus is $445 a month, plus voice agent minutes | Business is $115 a month plus a Sona pack; Scale for phone support is $175 | Five Expert seats at $49 each with Power Dialer included, plus $9 per user/month for AI Conversation Intelligence |
JustCall Pricing vs. OpenPhone (Quo) Pricing
One note before the numbers, because it's the most common mistake in a JustCall vs OpenPhone pricing comparison. JustCall publishes annual prices only. Quo's pricing page defaults to a monthly toggle, so the $19 you see first isn't the same basis as JustCall's $29. Everything below leads with annual pricing for both, with Quo's monthly figures in brackets.
JustCall Pricing
Here is what JustCall pricing looked like on the vendor's own page during QA in September 2026.
- Team: $29 per user/month, two license minimum. IVR and call menus, the messaging suite, team analytics, local numbers in 70+ countries, API up to 1,800 requests an hour.
- Pro: $49 per user/month. Adds the power dialer, bulk SMS campaigns, queue callback, intelligent routing, the Salesforce CTI, and advanced analytics.
- Pro Plus: $89 per user/month. Adds the AI notetaker, SMS co-pilot, coaching comments, real time agent assist, script compliance, call scoring, and sentiment analysis.
- Business: custom, 10 license minimum. Unlimited calling and SMS, SSO, an enterprise grade SLA, HIPAA and GDPR compliance, and a dedicated phone support line.
- SalesPro: custom, two license minimum. The outbound line, with the dynamic dialer and predictive dialing at up to 10 lines.
- Minimums and extras: the cheapest live account is $58 a month because of the seat minimum. The voice agent is a per minute add-on on every tier, with the first 100 minutes free and volume discounts published down to $0.15 per minute. The trial runs 14 days with no credit card.
OpenPhone (Quo) Pricing
Here is what OpenPhone pricing looked like on the vendor's own page during the same QA pass.
- Starter: $15 per user/month ($19 monthly). One number per user, unlimited calling and messaging to the US and Canada, voicemail transcripts, the Quo API, Sona with 1,000 credits a month, manual call recording, email support, and a number shared with up to 10 paid users.
- Business: $23 per user/month ($33 monthly). Adds phone menus, automatic recording, AI summaries on all calls, group calling, transfers and ring order, analytics, live chat, and the HubSpot and Salesforce integrations.
- Scale: $35 per user/month ($47 monthly). Adds AI call tags, dedicated onboarding, priority support, and inbound phone support Mon to Fri, 8am to 5pm PT.
- Extras: Sona's included allowance is 10 calls a month, and packs run $25 for 40 calls, $49 for 100, $99 for 250, and $199 for 600, with per call overage between $1.00 and $0.45. Extra numbers are $5 a month, international calling and messaging is billed per minute and per message, automated SMS through the API, Zapier, or Make is $0.01 each, and US carrier registration adds $19.50 once plus $1.50 to $3 a month. The trial is 7 days.
Pricing Compared Line by Line
| Pricing dimension | JustCall | OpenPhone (Quo) | CloudTalk |
|---|---|---|---|
| Entry price (per user/month, annual) | $29, two license minimum | $15 ($19 monthly) | $25, with Essential at $29 and Expert at $49 |
| Call and text limits | 1,000 outbound and 1,000 inbound minutes per user, pooled; 500 to 1,000 SMS segments by tier | Unlimited to US and Canada, fair usage; international per minute or message | Regional calling bundles by plan, numbers in 160+ countries |
| How AI is charged | Voice agent per minute on any tier; the analysis set bundled into Pro Plus | Sona included with 10 calls a month, then packs at $25 to $199 | Always add-ons: $9 per user/month for AI Conversation Intelligence, from $99 a month for 200 AI Voice Agent minutes |
| HIPAA and BAA | Business tier, custom priced | "Talk to sales" | HIPAA tooling with BAA support |
| Extra phone numbers | Two free per account | $5 per number per month | Local numbers in 160+ countries, porting supported |
For a third reference point on the same line items, CloudTalk pricing starts at $25/user/month, billed monthly or annually, with no seat minimum. See all plans.
JustCall Integrations vs. OpenPhone (Quo) Integrations
JustCall Integrations
JustCall's plan cards advertise 100+ CRM and data integrations, though the FAQ further down the same pricing page says 80+, so treat the headline as approximate. The named set covers the sales stack: Salesforce, HubSpot, Pipedrive, Zoho, Copper, Zendesk, Intercom, Slack, Apollo, Outreach, Salesloft, HighLevel, and Zapier. Watch the Salesforce CTI, which starts on Pro rather than Team. API access is rate tiered at 1,800, 3,600, and 5,400 requests an hour.
OpenPhone (Quo) Integrations
Quo's list is shorter and grouped differently. Email, Slack, Zapier, Make, Google Contacts, webhooks in beta, the Quo API, and an MCP connector for ChatGPT and Claude are on every plan, which is generous at $15 a user. The CRM side is the gated part: HubSpot and Salesforce need Business, and Zoho CRM, Pipedrive, Attio, Clio, Jobber, Gong, and HighLevel round out the catalog. Anything off that list you build through Zapier, Make, or the API.
Integration Capability Compared
| Integration capability | JustCall | OpenPhone (Quo) | CloudTalk |
|---|---|---|---|
| Native integrations | 100+ on plan cards, 80+ in the pricing FAQ | Roughly 17 named connectors plus Zapier and Make | 95+ standard CRM, helpdesk, and ATS integrations from Essential, from a catalog of 100+ apps |
| Salesforce and HubSpot depth | HubSpot from Team; Salesforce CTI from Pro | Both from Business | HubSpot from Essential; Salesforce Ecosystem integration on Expert |
| API access | Every tier, rate limited by plan | Quo API on every plan, webhooks in beta | API and data sync from Essential, plus webhooks and CloudTalk MCP |
| Developer effort for the long tail | Zapier plus the API | Zapier, Make, webhooks, or the API | Workflow designer for custom syncs, SMS triggers, and Slack alerts |
Security & Compliance: JustCall vs. OpenPhone (Quo)
JustCall Security & Compliance
- SOC 2 Type 2 and ISO 27001:2022, both published on JustCall's security and compliance page.
- GDPR compliance, with TLS and SSL in transit and AES-256 at rest.
- A HIPAA BAA on the custom priced Business tier, on JustCall's own template. They state they won't review or sign a customer's template.
- One inconsistency worth knowing: the FAQ on JustCall's pricing page still says SOC 2 Type 1 while the security page says Type 2. The security page is the more specific source.
OpenPhone (Quo) Security & Compliance
- Quo publishes much less. "HIPAA ready", the audit log, and the SOC 2 report are all "talk to sales" items in its plan comparison rather than plan features.
- The site footer carries an AICPA SOC badge, and Quo doesn't publish an ISO 27001 certification.
- In practice a regulated buyer has to get the current attestation and BAA terms from Quo's sales team rather than reading them off the pricing page.
Security & Compliance Compared
| Security and compliance | JustCall | OpenPhone (Quo) |
|---|---|---|
| GDPR | Published | Not published as a plan feature |
| SOC 2 | Type 2, on the security page | Report on request; AICPA badge in the footer |
| ISO 27001 | ISO 27001:2022 | Not published |
| HIPAA and BAA | Business tier, JustCall's template only | "HIPAA ready", handled through sales |
| Encryption | TLS and SSL in transit, AES-256 at rest | Not published in the plan comparison |
The CloudTalk Angle:
If you're buying for a regulated team, CloudTalk's security and compliance coverage spans GDPR, SOC 2, and HIPAA tooling, including BAA support and PHI handling on the recording and transcription pipeline, without routing you to a custom tier first.
Usability & Reliability: JustCall vs. OpenPhone (Quo)
JustCall Usability & Reliability
- More surface to configure, because there's more product: dialing modes, campaigns, call menus, routing rules, analytics, and AI settings each have their own setup.
- The trial is long enough to test properly: 14 days, no credit card, JustCall AI included.
- An enterprise grade SLA is listed on Business and SalesPro, so the reliability commitment is a contract term at the top of the ladder rather than a platform wide promise.
- Support scales with spend: email and chat lower down, a dedicated phone line on Business and SalesPro.
OpenPhone (Quo) Usability & Reliability
- Much less to configure, which is the point: a number per user, a shared inbox, Sona on by default.
- The trial is 7 days, which is tight if you want to test AI behavior on real call volume.
- Leaving is straightforward, with self service cancellation and numbers held for 60 days.
- The support ladder is the friction point: email on every plan, chat from Business, a phone line only on Scale during Pacific business hours.
Usability & Reliability Compared
| Dimension | JustCall | OpenPhone (Quo) |
|---|---|---|
| Configuration surface | Wide: dialers, campaigns, menus, routing, analytics, AI | Narrow by design: numbers, shared inbox, Sona |
| Free trial | 14 days, no credit card | 7 days |
| Support by tier | Email and chat lower down; phone line on Business and SalesPro | Email everywhere, chat from Business, phone on Scale |
| Published SLA | Enterprise grade SLA on Business and SalesPro | Not published |
| Cancellation | Not published on the pricing page | Self service in app, numbers held 60 days |
The trade-off runs in opposite directions: JustCall asks you to configure more to get more, Quo asks you to accept less so there's less to run. CloudTalk sits between them, pairing dialers and AI add-ons with native CRM sync, call flow building that doesn't need a developer, and live call monitoring for supervisors who need to see the queue as it happens.

|---|---|
| $15 per user/month billed annually, no published seat minimum | No dialer, no video calling, and no real time queue monitoring at any tier |

Price the trade-offs against your own call volume
Which Team Fits Which Platform?
Fit depends on how many calls you place a day, on whether outbound automation is core to the workflow, and on how fast the team is growing. None of that is a verdict on product quality. The same three questions decide whether you need virtual call center software at all, or just a shared number that rings the right person.
| JustCall is the right fit for... | OpenPhone (Quo) is the right fit for... |
|---|---|
| Sales teams running high volume outbound campaigns | Small collaborative teams under about 20 seats |
| Teams that need bulk SMS or WhatsApp automation | Teams that want one shared number without a call center buildout |
| Teams buying local numbers across several countries | Teams whose calling stays inside the US and Canada |
| Regulated teams that need a signed BAA and can budget the Business tier | Teams that want an AI agent answering calls without a separate contract |
| Managers who coach on recordings, scores, and sentiment | Owners who want the phone system live the same afternoon |
JustCall vs. OpenPhone (Quo): The Verdict
The choice between these two is a scope question. JustCall is priced and built for teams whose revenue depends on outbound volume and on what managers learn from recordings. Quo is priced and built for teams who want a shared number and an AI agent picking up, with nobody assigned to administer it. Match the platform to the workflow you actually run, and you'll land on the right one.
Choose JustCall if you…
- Run outbound campaigns where reps dial lists rather than individuals.
- Send bulk SMS or WhatsApp at campaign volume, not one thread at a time.
- Want AI call scoring, script compliance, and sentiment analysis on top of summaries.
- Need a HIPAA BAA and can work inside a custom priced tier with a 10 license minimum.
- Buy local numbers in several countries and want them on the entry plan.
- Already have more than 10 seats, so the two license minimum is irrelevant.
Choose OpenPhone (Quo) if you…
- Run a team of roughly five to 20 people sharing one business number.
- Call and text mostly inside the US and Canada and don't want metered minutes.
- Want an AI agent answering routine calls without a separate contract.
- Don't dial lists, so a missing dialer costs you nothing.
- Want the lowest published entry price and a self service exit.
- Prefer a tool nobody has to administer over a tool that can do everything.

Frequently Asked Questions
JustCall is a cloud phone system built for sales and support teams running high call and message volume. It combines dialing modes, bulk SMS and WhatsApp campaigns, IVR and call routing, CRM integrations, and an AI layer for summaries, scoring, and sentiment, across plans from $29 per user/month billed annually plus two quote priced tiers.
The drawbacks are commercial more than technical. Team carries a two license minimum, the power dialer needs Pro at $49 per user/month, predictive dialing is only in the quote priced SalesPro line, and the full AI set arrives on Pro Plus at $89. The HIPAA BAA is limited to the custom priced Business tier, on JustCall's own template.
OpenPhone (Quo) is a mobile first business phone system for small teams: one number per user, shared numbers, unlimited calling and messaging to the US and Canada under fair usage, voicemail transcripts, and the Sona AI agent on every plan from $15 per user/month billed annually. OpenPhone rebranded to Quo on 23 September 2025, keeping the same product under a new name.
Quo's published plan comparison lists no auto, power, or predictive dialer, no video calling, and no real time queue monitoring, so it isn't a contact center replacement. Phone menus, analytics, automatic call recording, and the HubSpot and Salesforce integrations start on Business, and phone support is Scale only, during Pacific business hours.
JustCall costs $29 per user/month on Team, $49 on Pro, and $89 on Pro Plus, all billed annually with a two license minimum, and the Business and SalesPro tiers are quote priced. Two seats is the floor, so no live JustCall account costs less than $58 a month. The AI voice agent is a per minute add-on on any tier, with volume discounts published down to $0.15 per minute.
Quo costs $15 per user/month on Starter, $23 on Business, and $35 on Scale billed annually, or $19, $33, and $47 billed monthly. The extras add up separately: additional numbers at $5 a month, Sona credit packs from $25 to $199, international calling and messaging billed per minute and per message, and US carrier registration at $19.50 once plus $1.50 to $3 a month.
OpenPhone (Quo) is cheaper on sticker price: Starter is $15 per user/month billed annually against JustCall Team at $29, and JustCall's two license minimum lifts its smallest account to $58 a month. The running total differs, because Quo adds $5 per extra number and Sona credit packs from $25. CloudTalk's Starter sits between them at $25 per user/month with IVR and skill based routing included.
Both JustCall and OpenPhone (Quo) offer a free trial, on different terms. JustCall's runs 14 days with no credit card and JustCall AI switched on. Quo's runs 7 days, which is tight if you want to watch Sona handle a normal week of inbound. CloudTalk's 14-day free trial also runs without a card.
JustCall covers most of a small call center's needs; OpenPhone (Quo) is not built for that job. JustCall has IVR from its entry plan, intelligent routing on Pro, and real time agent assist on Pro Plus, so the capability exists but sits across three tiers. Quo lists no dialer and no real time queue monitoring, which is why supervisors who need live queue visibility end up looking at real time wallboards instead.
Of the two, only JustCall publishes dialing automation. JustCall's power dialer arrives on Pro at $49 per user/month, and predictive dialing at up to 10 lines sits in the quote priced SalesPro line. OpenPhone (Quo) lists no dialer at any tier, so list work stays manual. CloudTalk's Smart Dialer starts on Essential, with Power Dialer included on Expert.
JustCall and OpenPhone (Quo) sell AI on different models rather than at different depths. JustCall keeps its AI voice agent as a per minute add-on on every tier, and bundles the analysis set into Pro Plus at $89 per user/month. Quo includes Sona on all three plans but rations it to roughly 10 handled calls a month. Our JustCall AI Voice Agent vs CloudTalk breakdown works through the per minute side.
Yes. Number portability is a carrier obligation, and you request the port from the provider you are moving to, not the one you are leaving. Quo holds your numbers for 60 days after cancellation, which gives you a window to finish the move. Keep the account open until the port completes, because cancelling first can strand the number. Our guide to porting a JustCall number walks through the paperwork.
JustCall's main competitors are the cloud phone systems chasing the same sales and support buyer: OpenPhone (Quo), CloudTalk, Aircall, Dialpad, RingCentral, and Nextiva. Which one belongs on your shortlist depends on whether you need outbound dialing, a shared number, or full contact center tooling, since the category splits along those lines rather than on price. Our CloudTalk vs JustCall comparison runs one of them against the same dimensions used above.
For SMBs this is a fit question rather than a ranking. JustCall fits SMBs running outbound campaigns and bulk messaging, where dialers and AI scoring earn their keep. OpenPhone (Quo) fits SMBs that want one shared number and almost nothing to administer. CloudTalk fits SMBs that need contact center tooling, IVR, and routing from $25 per user/month without a custom quote. Our best virtual phone system for small business roundup compares the category more broadly.
