8x8 vs Zoom (2026): Which UCaaS Platform Wins for Sales Teams?

TL;DR#

• 8x8 wins on pure telephony depth: unlimited global calling to 14-48 countries, native contact center, and tighter analytics for outbound sales floors.
• **

Zoom** wins on meeting-first cultures: best-in-class video, the largest app marketplace, and a cheaper entry-point for teams already living in Zoom Meetings.

• Pricing is closer than you think. 8x8's X2 plan starts at $24/user/month, Zoom Workplace + Phone bundles land around $18.32-$25/user/month depending on commitment.
• Pick 8x8 if you run a high-volume calling team, need PCI-compliant payment capture, or sell into international markets.
• Pick Zoom if video is your primary channel, you want the deepest integration with Zoom IQ, or you already pay for Zoom seats company-wide.

What is the real difference between 8x8 and Zoom?#

8x8 and Zoom both sell unified communications (UCaaS), but they grew up on opposite sides of the stack. 8x8 has been a cloud PBX vendor since 2002 — phone-first, with video and chat layered on top. Zoom became a verb during 2020 by dominating video, then bolted on Zoom Phone in 2019 and a contact center (Zoom Contact Center) in 2022.

That history shows up everywhere in the product. 8x8's call routing, IVR, supervisor tooling, and PSTN coverage are richer and more mature. Zoom's video, webinars, whiteboards, and meeting AI are years ahead. The "8x8 vs Zoom" decision is mostly a question of which channel — voice or video — your revenue team lives in.

If your reps spend their day on outbound calls, prospecting through lists pulled from an email finder and dialing afterwards, the calling depth matters more than the video polish. If your reps spend their day in scheduled demos and customer calls, the equation flips.

How do 8x8 and Zoom pricing plans compare in 2026?#

8x8 stopped publishing public pricing in 2022 and now quotes per-customer. Resellers and review sites converge on these published rates for new customers:

| Plan | 8x8 |

Zoom Workplace + Phone | |---|---|---| | Entry seat | X2 – $24/user/mo | Workplace Pro + Phone Pro – $18.32/user/mo | | Mid tier | X4 – $44/user/mo | Workplace Business + Phone Power Pack – ~$25/user/mo | | Top tier | X6/X7/X8 (CCaaS) – $85-140/user/mo | Workplace Enterprise + Contact Center – ~$69/user/mo | | Free meeting tier | 40-min meetings, 50 participants | 40-min meetings, 100 participants | | Unlimited calling countries | 14 (X2) → 48 (X4) | 1 (US/CA only on Metered) → unlimited domestic | | Minimum commitment | Annual, 5-seat minimum on most plans | Monthly billing available |

A few price gotchas:

• Zoom Phone is sold separately from Zoom Meetings. You can't get true 8x8 parity without buying Workplace + Phone + (optionally) Contact Center.
• 8x8 X4 is the real apples-to-apples competitor to Zoom Workplace Business + Phone, and it's the plan that unlocks unlimited calling to 48 countries — the killer feature for international SDR teams.
• Contact center pricing flips Zoom's way. Zoom Contact Center starts around $69/user/mo for Essentials; 8x8's X6 (voice contact center) starts at $85/user/mo.

Which has better call quality and PSTN reach?#

Both vendors publish 99.999% uptime SLAs ("five nines"), but the underlying networks are different. 8x8 owns its global Tier-1 voice network with PoPs in 35+ countries — they peer directly with regional carriers, which is why their international quality scores beat Zoom Phone in most independent MOS testing.

Zoom Phone runs on a mix of Zoom-owned infrastructure and partner carriers (BYOC is supported). In North America, the call quality is indistinguishable in side-by-side testing. Outside North America, Zoom Phone availability is uneven — as of 2026, native Zoom Phone numbers are available in ~48 countries; 8x8 covers all of those plus an additional 8 with native local numbers and 120+ with virtual numbers.

Practical takeaway for outbound sales:

• Calling US/Canada-only? Either works. Pick on price and integrations.
• Calling EU + APAC? 8x8 is the safer default. Local-presence dialing across more geographies, native number portability, fewer "your call is breaking up" moments.
• Need toll-free + e911 + emergency response in unusual jurisdictions? 8x8's enterprise team handles edge cases more gracefully.

Is 8x8 or Zoom better for contact centers?#

This is where the comparison gets interesting. Both have native contact centers, but their philosophies differ.

8x8 Contact Center (X6/X7/X8) is a top-quadrant CCaaS in Gartner's 2024 Magic Quadrant for CCaaS. Skills-based routing, omnichannel queues (voice, email, chat, social, SMS), quality management, speech analytics, and outbound predictive dialer all ship native. The agent desktop is a single pane covering UC + CC, which means a supervisor can pull any agent into a coaching call without leaving the app.

**

Zoom Contact Center** launched in 2022 and is catching up fast. It's video-native (the only major CCaaS that lets a contact-center agent pivot to face-to-face with a customer in one click), Workforce Engagement Management is built-in, and Zoom AI Companion for Contact Center handles real-time agent assist and post-call summaries. It's missing the depth of 8x8's outbound dialer and the granularity of 8x8's reporting.

If you sell SDR services or run an outbound BDR pod doing 100+ dials a day per rep, 8x8 still has the edge. If you run inbound CX with screen-share + video escalation as a wedge (think wealth management, telehealth, premium support), Zoom Contact Center is the more modern bet.

How do the integrations stack up?#

Both connect to the obvious CRMs — Salesforce, HubSpot, Zendesk, Microsoft Dynamics, ServiceNow. The differences show up in three places.

Marketplace depth. Zoom App Marketplace has 2,800+ apps and is the broadest in the category. 8x8 has ~70 native integrations plus an open API.

Click-to-dial inside the CRM. 8x8's Salesforce integration includes inline screen-pop with full call recording and disposition logging by default. Zoom Phone for Salesforce reached parity in late 2024 but still requires more admin setup.

Sales engagement. Both integrate with Outreach, Salesloft, and Apollo for click-to-dial. Neither has the kind of native power-dialing UX you get from a purpose-built dialer like JustCall or Aircall. If you need parallel dialing or AI-assisted call coaching, layer a dialer on top of either — or use a workflow that pulls verified numbers via a phone finder and dials through your existing UC platform.

For data flowing in, both expose webhooks. 8x8's developer portal is more REST-centric; Zoom leans heavily on its own SDKs and the Zoom Apps framework.

What about meetings, video, and chat?#

This is Zoom's home turf and it shows.

Zoom Meetings still defines the category: gallery view of 49+, immersive view, sub-rooms, polls, whiteboards, breakout coaching for managers, and Zoom AI Companion that drafts meeting summaries, action items, and follow-up emails. The 2026 release added Zoom Docs as a Workplace tab and pushed AI Companion into the free tier for paid Workplace accounts.

8x8 Meet is functional and includes unlimited 1080p video, virtual backgrounds, and breakouts on the X2 plan. It is not in the same league as Zoom for large webinars or external-facing demos. The 8x8 Work mobile app is decent; the desktop client is utilitarian.

Team chat. Both have native persistent chat — Zoom Team Chat threads cleanly into channels, while 8x8 Work chat feels closer to Slack's older paradigm. Neither replaces Slack or Microsoft Teams if that's already your work hub.

Which is better for outbound B2B sales teams?#

For pure outbound — cold calling, multi-touch sequences, SDR pods — the answer is usually 8x8, for four reasons.

1. International coverage. Unlimited dialing to 14-48 countries on X2/X4 means your London SDR can call Madrid prospects without a per-minute meter ticking.
2. Outbound dialer. Native predictive dialer in X6+ removes the need to bolt on a separate tool.
3. Local presence. 8x8 supports dynamic caller ID by region; Zoom's local-presence add-on is newer and US-only.
4. Reporting. 8x8's Analytics Essentials surfaces call disposition, talk time, dispositions, and queue stats out of the box. Zoom's reporting is improving but still feels meeting-shaped.

That said, if your outbound motion runs through video — for example, you record personalized 30-second Loom-style intros via Zoom Clips and embed them in cold emails — Zoom's content workflows win.

A common stack we see at high-performing outbound teams: enrich and verify lead lists with an email verifier, pull mobile numbers via Tomba's phone finder, then dial through 8x8 (or Zoom Phone) with the CRM auto-logging dispositions. The phone system is the last mile; the data quality is what makes the dial worth making.

What do real reviews say on G2 and Gartner?#

We pulled the rolling 12-month averages as of Q1 2026:

| Source | 8x8 |

Zoom Phone | Zoom Contact Center | |---|---|---|---| | G2 overall | 4.1 / 5 (470 reviews) | 4.5 / 5 (590 reviews) | 4.5 / 5 (110 reviews) | | G2 ease of admin | 8.3 | 8.7 | 8.6 | | G2 quality of support | 8.4 | 8.6 | 8.9 | | Gartner Peer Insights (UCaaS) | 4.4 / 5 | 4.5 / 5 | — | | Gartner MQ position (UCaaS) | Leader | Leader | — | | Gartner MQ position (CCaaS) | Leader | Visionary | — |

A few patterns from the reviews themselves:

• 8x8's most common complaint is the admin console — too many sub-portals, a steeper learning curve for IT.
• Zoom Phone's most common complaint is feature parity gaps for power users coming from a legacy PBX (call-park nuances, attendant console depth).
• Both vendors get high marks for uptime; the public outage history backs this up.

You can verify the latest scores yourself on G2 and Gartner Peer Insights.

When should you pick 8x8?#

Pick 8x8 if any of these describe you:

• You make more than 50 calls per rep per day.
• You sell internationally and need bundled unlimited dialing to EU/APAC/LATAM.
• You operate (or plan to operate) a voice-led contact center with predictive dialing.
• You need PCI-compliant payment capture in the IVR (insurance, fintech, ecommerce support).
• You want a single vendor for UC + CC instead of bolting on a CCaaS later.

When should you pick Zoom?#

Pick Zoom if any of these describe you:

• Video is the primary channel — demos, customer onboarding, sales calls.
• Your team already runs on Zoom Meetings and you want one bill.
• You sell into mid-market/enterprise where Zoom is the default video tool buyers expect.
• You need a deep app marketplace because your stack is sprawling.
• You're starting fresh, want monthly billing, and don't want a 5-seat annual minimum.

What are the alternatives to 8x8 and Zoom?#

The UCaaS market isn't a two-horse race. Worth considering before you sign:

• RingCentral — the legacy challenger, deepest PBX feature set, strongest analyst position alongside 8x8.
• Dialpad — AI-native, best real-time transcription and sentiment, lighter on contact center depth.
• Microsoft Teams Phone — the right answer if your company already pays for M365 E5; calling plans bolt on cheaply.
• Google Voice (Workspace) — fine for small teams up to ~25 reps; not built for contact center.
• Aircall / JustCall — sales-team-first; pair with Slack or Teams for non-call collab.

Final verdict: 8x8 vs Zoom in 2026#

Both vendors are Leaders. Both will let you ditch your legacy PBX and consolidate phone, video, and chat. The honest summary:

• 8x8 wins on voice depth. Bigger PSTN footprint, better outbound tooling, stronger native CCaaS, better international economics.
• Zoom wins on collaboration breadth. Better video, bigger marketplace, more AI surface area, lighter commitment terms.

If you're a B2B SaaS company doing inside sales and customer success calls, Zoom Workplace + Phone is the simpler, cheaper, easier-to-adopt choice. If you're an outbound-heavy revenue org, a BPO, or running a contact center as the front door to the business, 8x8 is the more serious tool.
