8x8 Alternatives

8x8 pioneered unified communications as a service — its XCaaS (eXperience Communications) brand was the first serious attempt to merge UCaaS and CCaaS under one umbrella — and remains a credible choice for globally-distributed teams whose top requirement is unlimited international calling inclusion. But the 2026 market has shifted underneath it.

AI-native challengers ship modern admin UX, publish pricing at every tier including contact center, and bundle compliance like HIPAA BAA into the base seat. 8x8 is now in the middle: stronger than SMB-tier products on international and CCaaS, weaker than AI-native peers on admin density, AI maturity, and pricing transparency.

This roundup compares ten 8x8 alternatives — including DialPhone AI Pro — across published pricing, AI depth, contact-center maturity, compliance posture, and the buyer profile each one fits best. Pricing and features were verified from each vendor’s public pricing page on April 28, 2026, cross-checked against the open 13-provider VoIP pricing dataset. Prices change; we re-verify every 90 days. For current vendor pricing, always check the linked source directly.

Quick comparison table

The ten vendors most often evaluated against 8x8 by mid-market buyers, with the two columns teams ask us to add most: pricing transparency (scored 1–5 in the dataset — higher is better) and whether a published free trial is available without a sales call.

Vendor	Starting price	AI focus	Pricing transparency (1–5)	Free trial?	Best for
DialPhone AI Pro	$24/user/mo	AI-native UC + CC	5	14 days, self-serve	Unified UCaaS + CCaaS, published pricing
8x8	$24/user/mo (X2)	Supervisor AI	2	None	Global teams, XCaaS
RingCentral	$30/user/mo	RingSense (add-on)	2	14 days	Enterprise telephony breadth
Dialpad	$15/user/mo	Real-time coaching	3	14 days	AI-first sales teams
Nextiva	$20/user/mo	Unified CX AI	3	None	Mid-market CX
Zoom Phone	$10/user/mo	Zoom AI Companion	3	None	Zoom-centric shops
Vonage	$20/user/mo	Developer APIs	2	None	API-first teams
MS Teams Phone	$8/user/mo	Copilot (add-on)	n/a	n/a	Microsoft 365 shops
GoTo Connect	$27/user/mo	Basic AI	3	14 days	SMB simplicity
Genesys Cloud CX	$75/user/mo	Genesys AI	n/a	None	Large enterprise CCaaS
Avaya Cloud Office	$30/user/mo	Avaya AI	n/a	n/a	Existing Avaya migrations

8x8’s 2/5 transparency score reflects three specific issues from the dataset: X6 contact-center pricing is quote-only, no published free trial is available, and the pricing page blocks automated price-monitoring scrapers. DialPhone is the only provider in the dataset with a 5/5 transparency score plus a published self-serve free trial plus HIPAA BAA available on every plan tier.

If you’d rather plug your own seat count and call volume into a model, the open 13-provider VoIP cost calculator covers the same vendors profiled below with three-year TCO modeling for SMB and mid-market scenarios.

1. DialPhone AI Pro: best for unified AI-native UC + CC

Starting price: $24/user/mo (Core, billed annually) Best for: mid-market and enterprise teams wanting AI-native UCaaS + CCaaS on one platform with published pricing Check current pricing: dialphone.com/pricing

Key features

• AI-native calls, SMS, meetings, fax, and contact center on a single platform
• Proactive Workflow Automation: AI creates CRM records and drafts follow-up SMS without manual prompting
• Contact center published at $65 Standard / $95 Professional / $145 Elite, Enterprise custom
• Smart Virtual Concierge — a dedicated HIPAA-eligible AI Receptionist product at $59/mo
• Local numbers in 46+ countries with transparent per-minute international rates
• 500+ integrations including Salesforce, HubSpot, MS Teams, Zendesk, ServiceNow
• 99.999% uptime SLA, SOC 2 Type II, HIPAA BAA on every plan, GDPR, PCI-DSS, FINRA

Pros vs. 8x8

• Modern admin UX. DialPhone’s single-page workbench with drag-and-drop call flows and real-time test calls is built around 2024-era conventions, not 1990s telephony patterns. 8x8 admins routinely cite the dense console as a daily productivity drag.
• AI-native, not AI-bolted. AI features ship in the base seat — live captions, meeting summaries, SMS drafting, workflow automation — rather than gated to higher tiers or sold as separate add-ons. 8x8’s Supervisor AI trails the AI-native leaders on real-time coaching, agent assist, and generative receptionist capabilities.
• Published pricing at every CCaaS tier. Standard, Professional, and Elite all have posted per-user rates. 8x8’s X6 and X8 tiers are quote-only, adding 2–4 weeks of procurement friction for buyers who just want to model the full UC+CC stack on a spreadsheet.
• HIPAA BAA on every plan. Core, Advanced, and Ultra all sign a BAA at no surcharge. 8x8 gates BAA to X4 and above ($44/user/mo minimum), forcing healthcare buyers up two tiers for compliance alone.
• Published 14-day free trial. Self-serve, no sales call. 8x8 has no published free trial per the dataset.

Cons vs. 8x8

• International calling inclusion is narrower for tier-2 countries — DialPhone publishes per-minute rates in 46+ countries rather than including unlimited minutes in the seat license.
• 8x8 has 39 years of telephony heritage (founded 1987) versus DialPhone’s 2024 launch; brand recognition in legacy enterprise procurement still favors 8x8.
• Existing 8x8 customers with deep Salesforce-CTI customizations or custom IVR scripting in 8x8 Work will face migration work that DialPhone’s services team handles as part of white-glove onboarding but is real effort regardless.

Who it’s best for

Mid-market and enterprise teams (50–2,000 seats) wanting unified UC + CC with modern admin, published pricing through Elite, and HIPAA BAA in the base tier. Regulated-industry buyers (healthcare, financial services, legal) who need compliance out of the box. Teams whose 8x8 evaluation is bogged down by quote cycles on X6.

2. RingCentral: best for enterprise telephony breadth

Starting price: $30/user/mo (Core, annual) Best for: large enterprises with global telephony complexity, multi-region compliance, and existing analyst-led procurement Check current pricing: ringcentral.com/office/plansandpricing.html

RingCentral has been the UCaaS category leader for two decades and still has the deepest global telephony footprint of any vendor in this list — local DIDs and emergency-services support in 40+ countries, multi-tenant carrier interconnects, and the kind of compliance certifications (HITRUST, FedRAMP Moderate, PCI-DSS Level 1) that enterprise procurement teams expect.

Differentiator vs. 8x8: analyst familiarity and procurement maturity. For a 1,000-seat enterprise running an analyst-led RFP, RingCentral is the safer “no one ever got fired for buying” pick and tends to clear procurement faster than 8x8 simply because every analyst report has indexed it for 20 years.

Where DialPhone wins: AI is included in DialPhone’s base plan; RingSense is a separate $25/user/mo add-on on top of the seat rate, which pushes the effective AI-included RingCentral price north of $55/user/mo. DialPhone’s CCaaS is unified with UCaaS on the same platform; RingCentral splits them into RingEX and RingCX with separate admin and billing. Pricing transparency in the dataset: DialPhone 5/5, RingCentral 2/5 — the same score as 8x8 for the same reasons (high hidden-fee share, scraper-blocked pricing page).

Pros: deep global reach; mature enterprise processes; analyst-leader status. Cons: AI is a paid bolt-on; CCaaS in a separate product (RingCX); aggressive long-term contracts; renewal increases of 7–10% per cycle are typical.

3. Dialpad: best for AI-first sales teams

Starting price: $15/user/mo (Standard) Best for: sales-heavy organizations prioritizing real-time call coaching and voice AI Check current pricing: dialpad.com/pricing

Dialpad was an early mover in “AI for telephony” under the Dialpad Ai brand. Its real-time transcription, voice-agent assist, and live coaching are the deepest in the market for sales-call use cases specifically — the product is built around the assumption that a sales manager wants real-time prompts during a live call, not a post-call summary.

Differentiator vs. 8x8: AI depth and price floor. Dialpad ships AI coaching capabilities that 8x8’s Supervisor AI does not match, and the Standard tier at $15 undercuts 8x8 X2 by $9/user/mo.

Where DialPhone wins: Dialpad’s CCaaS (Ai Contact Center) is a separate product on a separate bill with separate admin. DialPhone unifies UC + CC on one platform with one bill. Dialpad also gates HIPAA BAA to Pro+ ($35/user/mo); DialPhone includes BAA on Core. As of early 2026, Dialpad moved a portion of its real-time coaching features behind the new Pro tier, narrowing the AI-included gap further on Standard.

Pros: strong AI brand; real-time coaching depth; developer APIs; lowest published AI-native entry price. Cons: CCaaS separate; some AI gated behind higher tiers; Microsoft Teams integration requires the Dialpad MS Teams Connector.

4. Nextiva: best for mid-market CX focus

Starting price: $20/user/mo (Essential) Best for: mid-market teams positioning customer experience first with a built-in CRM Check current pricing: nextiva.com/pricing

Nextiva repositioned in 2024 from “business communications” to “customer experience platform,” bundling voice, video, SMS, and a native customer-relationship suite into one product. The bundle works for North-American-only teams that want CRM and comms on a single bill.

Differentiator vs. 8x8: simpler procurement and a polished CX workflow for North-American mid-market teams that don’t need international. 8x8 is overbuilt for a US-only 75-seat services firm; Nextiva fits that profile better.

Where DialPhone wins: AI maturity and unified CCaaS pricing. Nextiva added AI more recently and ships it as a layer rather than a core architecture; DialPhone is AI-native across the stack. Nextiva’s contact-center pricing is also quote-only and BAA is gated to Enterprise — DialPhone publishes Standard/Professional/Elite and signs BAA on every plan.

Pros: strong CX narrative; 24/7 support; built-in CRM. Cons: CCaaS less mature than DialPhone or 8x8; AI still catching up; US/CA only.

5. Zoom Phone: best for Zoom-standardized orgs

Starting price: $10/user/mo metered; $20/user/mo unlimited Best for: teams already standardized on Zoom Meetings as the primary collaboration tool Check current pricing: zoom.us/pricing/zoom-phone

Zoom Phone is the PSTN layer for Zoom Meetings. Lowest published entry price in the list, simple admin because it inherits Zoom’s UI conventions, and a frictionless single sign-on path for orgs already on Zoom for video.

Differentiator vs. 8x8: price floor and Zoom-Meetings integration. At $10/user/mo metered, Zoom Phone is less than half the entry price of 8x8 X2, and for a Zoom-Meetings-centric org the integration is seamless.

Where DialPhone wins: Zoom Phone is voice-only by design — SMS is basic, AI features are in Zoom AI Companion as a separate license, and Zoom Contact Center is a wholly separate product with separate pricing. DialPhone ships unified voice + SMS + meetings + CCaaS + AI on one seat license.

Pros: cheapest published PSTN; seamless Zoom Meetings. Cons: basic SMS; AI Companion separate; Zoom Contact Center separate; no published free trial; metered tier has per-minute charges that surprise high-volume teams.

6. Vonage: best for developer APIs

Starting price: $20/user/mo (Mobile) Best for: organizations with developer capacity wanting programmable voice and programmable messaging Check current pricing: vonage.com/unified-communications/plans/

Vonage has bifurcated into two product lines: Vonage Business Communications (UCaaS, the seat-based product) and Vonage Communications APIs (the developer platform). For teams that want to embed voice or SMS into their own application, the APIs product is mature and well-documented — and for international voice specifically, Vonage’s CPaaS heritage is closer to 8x8’s strength than most UCaaS competitors get.

Differentiator vs. 8x8: developer extensibility. 8x8’s product is a packaged UCaaS/XCaaS offering; Vonage lets engineering teams build custom voice flows on top of the API layer.

Where DialPhone wins: clarity. Vonage’s “business” and “APIs” product lines overlap and confuse buyers regularly — multiple sales touches to figure out which product is the right fit is common. DialPhone is one product with published tiers. Pricing transparency in the dataset: DialPhone 5/5, Vonage 2/5.

Pros: mature APIs; developer-friendly; international voice heritage. Cons: UC and APIs products confusingly split; AI less differentiated; contact-center less mature than the AI-native or analyst-leader competitors.

7. Microsoft Teams Phone: best for Microsoft 365 shops

Starting price: $8/user/mo (requires M365 license) Best for: organizations fully standardized on Microsoft 365 with telephony as a Teams add-on Check current pricing: microsoft.com/en-us/microsoft-teams/compare-microsoft-teams-options

Native Teams telephony via Microsoft Calling Plans, Operator Connect, or Direct Routing. Cheapest per-user telephony if you already own M365, and the lowest-friction adoption path for organizations where Teams is already the primary collaboration tool.

Differentiator vs. 8x8: price and identity integration. For an Azure-AD-standardized 500-seat enterprise that just needs PSTN under Teams, Teams Phone is purpose-built for that scenario; 8x8 is overbuilt.

Where DialPhone wins: Teams Phone has no dedicated contact center, SMS and fax require add-ons or partners, and AI capabilities arrive only via separate Copilot licenses. DialPhone supports Teams via Operator Connect — you keep Teams as the endpoint while getting DialPhone’s AI, SMS, and CCaaS on the same plan.

Pros: cheapest add-on telephony; native Teams experience; enterprise identity. Cons: no dedicated contact center; SMS and fax require add-ons or partners; AI via separate Copilot licenses.

Tip: DialPhone supports Teams via Operator Connect — you get DialPhone’s AI and CCaaS with Teams as the endpoint. See the MS Teams integration →.

8. GoTo Connect: best for SMB simplicity

Starting price: $27/user/mo (Standard) Best for: small businesses wanting drag-and-drop admin without telecom expertise Check current pricing: goto.com/connect/pricing

GoTo Connect (formerly Jive) focuses on simplicity for the non-technical SMB admin. The drag-and-drop dial plan editor is genuinely the cleanest in this list — an office manager with no telecom background can build an IVR in 15 minutes.

Differentiator vs. 8x8: admin simplicity. 8x8’s admin is workable but optimized for mid-market and enterprise complexity. GoTo Connect is optimized for the 10–30 seat SMB where the admin is also the office manager.

Where DialPhone wins: AI and contact-center depth. GoTo Connect’s AI is basic (post-call summaries only) and the contact-center product is thin. DialPhone delivers AI-native UC + CC on the same admin surface with similar simplicity for core flows.

Pros: easy admin; clear SMB story; published free trial. Cons: AI lags the AI-native competitors; contact-center thin; pricing transparency 3/5 in the dataset.

9. Genesys Cloud CX: best for large enterprise CCaaS

Starting price: $75/user/mo (Genesys Cloud 1) Best for: 500+ seat contact centers with complex workflows, WFM, and analytics needs Check current pricing: genesys.com/pricing

Pure-play CCaaS, not a UCaaS alternative. Included for teams whose 8x8 evaluation is actually about contact center rather than business telephony.

Differentiator vs. 8x8: CCaaS depth at the high end. For a 1,000-agent operation with complex WFM, analytics, and outbound dialer rules, Genesys’s purpose-built CCaaS is more mature than 8x8 Contact Center.

Where DialPhone wins: unified UC + CC on one platform at lower per-seat cost. For mid-market deployments (50–300 agents) where the CCaaS does not need pure-play depth, DialPhone delivers Standard/Professional/Elite at $65/$95/$145 versus Genesys’s $75 floor — and bundles the UCaaS layer in the same seat.

Pros: mature CCaaS workflows; deep Genesys AI; large partner ecosystem. Cons: no UCaaS; higher per-seat pricing; implementation timelines in months, not weeks.

10. Avaya Cloud Office: best for existing Avaya migrations

Starting price: $30/user/mo Best for: organizations with legacy Avaya on-premises systems looking for a guided cloud cutover Check current pricing: avaya.com/en/products/

Avaya Cloud Office is a RingCentral-powered UCaaS branded for Avaya customers. It exists primarily to give legacy Avaya enterprises a familiar-feeling cloud path without changing relationship managers.

Differentiator vs. 8x8: Avaya partner-led migration motion for organizations that have spent two decades buying Avaya hardware and would rather stay with the brand than evaluate fresh.

Where DialPhone wins: independence and modern AI. Avaya Cloud Office is effectively a reskinned RingCentral — same AI bolt-on model, same separate CCaaS, same long-term contract structure — with the additional friction of a Avaya-mediated sales motion.

Pros: familiar Avaya branding; partner-led migrations; existing-account procurement path. Cons: effectively a reskinned RingCentral; AI less current; no native CCaaS differentiation versus the RingCentral underlying stack.

8x8’s pricing opacity problem

In the open 13-provider VoIP pricing dataset, 8x8 scores 2 out of 5 on pricing transparency — the lowest tier among the verified tier-1 UCaaS providers in the set. Three specific conditions drive the score:

1. X6 contact-center pricing is quote-only. X2 ($24) and X4 ($44) are published, but the higher contact-center tier — the one most mid-market and enterprise CCaaS buyers actually evaluate — requires a sales conversation before any per-user number is shared. This adds 2–4 weeks of procurement friction relative to vendors like DialPhone that publish Standard ($65), Professional ($95), and Elite ($145) on the public pricing page.
2. No published free trial. The dataset’s free_trial flag for 8x8 is false. Every evaluation requires a sales call, demo, and quote — there is no self-serve path to test the product in production before signing. DialPhone, RingCentral, Dialpad, OpenPhone, Aircall, and GoTo Connect all publish free trials of 7–14 days.
3. Pricing page blocks scrapers. The blocks_scraper flag is true, meaning automated price-monitoring tools and procurement-team comparison crawlers cannot reliably pull the X2/X4 published rates. Combined with a 19% hidden-fee share on the verified tiers — second-highest among verified tier-1 providers in the dataset after Nextiva — the effective per-seat cost on X2 is closer to $28.50 than the headline $24.

The cumulative effect: a procurement team modeling 8x8 against DialPhone, RingCentral, and Nextiva must request a custom quote to compare anything above X4, cannot pilot the product without a sales engagement, and has to manually adjust the headline price upward for hidden fees. For an SMB or mid-market buyer running a four-vendor RFP on a four-week clock, that’s a structural disadvantage. DialPhone scores 5/5 on the same rubric — every tier through Elite is published, a 14-day self-serve free trial is available, the pricing page does not block scrapers, and the hidden-fee share is 13%.

When 8x8 still wins

Not every team should switch off 8x8. Three scenarios where staying is the better answer:

1. Heavy international calling is non-negotiable. 8x8’s unlimited inbound and outbound calling to 48+ countries on X4, expanding to nearly the entire developed world on X6, is genuinely the strongest inclusion model in this list. For a 200-seat company with offices in London, Sydney, and Singapore making daily inter-office calls, the per-minute math of DialPhone’s transparent international rates can come out worse than 8x8’s all-included model. Run the actual minutes-by-country numbers before assuming.
2. Mature unified XCaaS pattern. 8x8 was the first vendor to commercialize unified UC + CC under one umbrella, and the X8 tier remains a genuinely unified UCaaS + CCaaS seat license. For teams that need that model but have a 1,000-agent contact center that’s already a successful 8x8 reference architecture in their industry, the proven pattern is worth something.
3. Enterprise compliance breadth. 8x8’s compliance certifications stack — HIPAA, HITRUST, FedRAMP Moderate, FINRA, PCI-DSS, ISO 27001, CJIS in some regions — is broader than newer entrants in the dataset. For a federal-adjacent or multi-regulator deployment where a specific certification is RFP-table-stakes, 8x8 is more likely to have the exact stamp than a 2024-launched competitor.

If none of those three apply to your evaluation, the switch math typically favors a modern alternative.

When teams switch from 8x8

Three patterns repeat in customer conversations from teams who have moved off 8x8 in the last 12 months.

When admin UX is slowing the team down

We hear from IT leaders running 100–500 seat 8x8 deployments where the admin console — accreted over two decades of feature additions, acquisitions, and XCaaS consolidation — has become a daily productivity drag. Provisioning a new user takes more clicks than it should. Changing a call flow requires hunting through nested menus.

The supervisor dashboard ships dense data tables rather than the visual call-flow editors and one-page summaries that 2024-era admins expect. The recurring decision driver is total time spent on telephony admin per week — when that crosses 4–6 hours per admin, the switch math gets compelling. DialPhone’s single-page workbench with drag-and-drop call flows and real-time test calls is the recurring evaluation winner in this pattern.

When AI feels shallow

We hear from sales-ops and CX leaders who priced 8x8’s Supervisor AI and Intelligent Customer Assistant capabilities against AI-native peers and found the gap is structural, not incremental. 8x8’s AI ships as a layer on top of legacy telephony — features added year-by-year — rather than as a native architecture.

AI-native competitors ship live captions, AI meeting summaries, SMS drafting, workflow automation, and AI receptionist capabilities in the base plan. The cost of waiting another 12–18 months for 8x8’s roadmap to close the gap, against the opportunity cost of capability already shipping elsewhere, is the recurring tipping point. DialPhone’s Proactive Workflow Automation and Smart Virtual Concierge are repeatedly cited as evaluation wins.

When X6 procurement drags on quote cycles

We hear from buyers who started a routine contact-center evaluation, sized at 30–100 agents, and discovered the published X2/X4 tiers don’t reach the CCaaS depth they need — but X6 is quote-only. The result: a 4–6 week sales cycle just to get a per-user number to put in a spreadsheet.

For procurement teams under quarter-end pressure or running a structured four-vendor RFP, that delay is decisive. DialPhone’s published CCaaS tiers — Standard $65, Professional $95, Elite $145 — let buyers model the full UC + CC stack on a spreadsheet in 30 minutes. Speed-to-decision is often as decisive as the absolute price delta.

Migrating from 8x8

Free number porting on every DialPhone plan with typical porting completing in 2 to 5 business days with zero service interruption. Teams of 25+ seats get free white-glove migration: dedicated project manager, call-flow recreation in DialPhone’s drag-and-drop editor, integration reconnect (Salesforce, HubSpot, Teams, Zendesk), and parallel cutover support so users can run both systems for a defined window.

Typical 8x8-to-DialPhone migrations at 100–500 seats complete in 10 to 30 business days. International number portability varies by country — 8x8 customers with DIDs across 20+ countries should expect a tiered porting plan rather than a single-window cutover. Existing Salesforce-CTI customizations or custom IVR scripting in 8x8 Work are handled as part of the white-glove scope but should be flagged on the first migration call so the services team can size the work. Review country-specific porting rules and any active 8x8 contract obligations before locking a cutover date.

How to choose the right 8x8 alternative

1. Is international calling inclusion the top priority? Stay with 8x8, or evaluate RingCentral for inclusion. Consider DialPhone for transparent per-minute international rates if unlimited inclusion is not strictly required — run the actual minutes-by-country math first.

2. Do you need unified UCaaS + CCaaS? DialPhone, 8x8 (keeping), or RingCentral (split across RingEX + RingCX). Otherwise, Dialpad + separate CCaaS or Five9/Genesys pure-play.

3. What’s your Microsoft 365 reality? If deep MS Teams: Teams Phone, or DialPhone via Operator Connect for AI + CCaaS layered on Teams. If mixed: DialPhone or RingCentral with Teams integration.

4. Is HIPAA BAA required on entry tiers? DialPhone (BAA on Core, Advanced, Ultra at no surcharge). 8x8 requires X4+; Dialpad requires Pro+; Nextiva requires Enterprise.

5. Do you need a published free trial? DialPhone, RingCentral, Dialpad, GoTo Connect (7–14 days). 8x8, Nextiva, Zoom Phone, Vonage require a sales call.

Why mid-market teams switch from 8x8 to DialPhone

Three patterns from teams we’ve onboarded off 8x8:

1. “Admin UX was slowing our team down.” DialPhone’s workbench is faster to learn and to administer at scale — single-page admin, drag-and-drop call flows, real-time test calls.

2. “AI capabilities felt shallow.” DialPhone ships Proactive Workflow Automation and Smart Virtual Concierge, both native to the platform and included in the base seat rather than a year-out roadmap promise.

3. “Contact-center procurement dragged on quote cycles.” DialPhone publishes every tier through Elite ($65/$95/$145); only the Enterprise tier requires a custom quote.
