JUSTCALL VS OPENPHONE COMPARISON

JustCall vs OpenPhone Pricing: Which Gives You More for Less?

Swipe to see the winner

JustCall Logo

JustCall

JustCall pricing starts at $29 per user/month (annual billing, two-user minimum. It includes standard tools like call routing and analytics, while advanced features such as predictive dialers and AI analytics require higher tiers. It’s well-suited for small sales or support teams, but pricing increases noticeably as you expand feature use or agent volume.

OpenPhone Logo

OpenPhone (now Quo)

OpenPhone pricing begins at $19 per user/month for the Standard plan. It offers shared numbers, call recording, messaging, and core integrations with HubSpot and Slack. While affordable and transparent, it lacks international numbers and advanced automation, making it best for startups or local teams prioritizing simplicity over scale.

Pricing Winner: OpenPhone

OpenPhone offers clearer, more predictable pricing that’s easier to manage for early-stage teams. JustCall’s tiered upgrades deliver more capability but can become expensive over time. For small businesses wanting fast setup and steady costs, OpenPhone provides stronger upfront value.

OpenPhone vs JustCall Voice AI: Who Handles Routine Calls Smarter?

Swipe to see the winner

JustCall Logo

JustCall

JustCall offers an inbound-only AI Voice Agent that answers calls, qualifies leads, books meetings, and handles FAQs. It’s available as an add-on at $0.99/minute and integrates with CRMs like HubSpot and Salesforce. The tool streamlines inbound workflows but doesn’t support outbound automation.

OpenPhone Logo

OpenPhone (now Quo)

OpenPhone takes a simpler route. It provides voicemail transcription and AI-generated call summaries of routine calls, but has no native AI voice agent or smart-dialing tools. Any deeper automation must be built through external integrations such as Zapier or HubSpot workflows, which makes setup basic but limited.

Voice AI Winner: JustCall

JustCall wins for having a real AI Voice Agent that can manage routine calls directly. Unfortunately, you can’t use their voice AI for outreach as it currently only supports automation of incoming calls. OpenPhone’s automation stops at transcription and summaries, making it best for small teams with minimal inbound volume.

G2 Reviews proof

The transition to CloudTalk was super smooth. Actually, agent productivity grew by 10% just as a direct result of the switch. We thought our sales team couldn’t handle more than 15 daily leads, but this year, on some days, they took care of 30 and even won more deals.

Franco Viale Leyva
Head of Commercial Performance at Poliglota

Our call volume tripled in only 2 years. Today, our agents get around 100,000 calls per quarter versus 30,000 back in 2020. With CloudTalk, we can now handle all of this communication easily. It was an excellent choice.

Frederico Lopes
Head of Customer Service at DiscoverCars

CloudTalk has grown on us from the very first moment. It’s a part of our daily workflow. Everyone in the company finds uses for it. From sales to support or onboarding. Without CloudTalk, we wouldn’t provide such outstanding service.
