1:1 comparison · Verified August 27, 2026 8x8 sells five distinct products, 8x8 Contact Center, 8x8 Engage, 8x8 CPaaS, 8x8 Work and 8x8 for Microsoft Teams, and prices none of them publicly. DialPhone sells business phone and contact center and publishes every tier below Enterprise. That, rather than any feature, is the decision most buyers actually face here.
The single most important correction on this page: 8x8 no longer publishes prices. Its plans and pricing page lists capabilities per product and routes every one to Request a Quote or Chat with Sales. The X2, X4, X6 and X8 price points that appeared in earlier versions of this page are not on 8x8’s current site and have been removed rather than re-estimated. Checked 27 August 2026 at 8x8.com/products/plans-and-pricing.

Pricing comparison
Only one side of this comparison can be costed from public information.
100-seat UCaaS team, annual billing, 12-month cost
- DialPhone Advanced: 100 × $34 × 12 = $40,800/year
- 8x8 Work: not calculable. 8x8 publishes no per-user price.
100-seat team that needs contact center
- DialPhone Advanced + Contact Center Professional: 100 × ($34 + $95) × 12 = $154,800/year
- 8x8 Work + 8x8 Contact Center: not calculable. Both are quote-only.
Earlier versions of this page put the 8x8 side at $52,800 a year for UCaaS and $175,000 to $230,000 a year with contact center. Neither figure is supported by anything 8x8 publishes, and both have been removed rather than replaced with a new estimate. If you want a number, request a quote and compare it against the DialPhone figures above, which are list prices before taxes, telecom fees and usage.
International calling
8x8 lists global coverage as a capability of 8x8 Work and 8x8 Engage but does not publish inclusive-country lists or prices. DialPhone publishes per-minute outbound rates. Compare 8x8’s quoted inclusion against DialPhone’s per-minute rates on your own destination mix; nothing on either vendor’s public pages settles it in advance.
AI capabilities compared
Base-plan AI
- DialPhone: AI live captions, transcription and summaries in Core. AI SMS drafting and Proactive Workflow Automation in Advanced.
- 8x8: publishes AI Studio as a product and lists AI-enabled self-service and conversational intelligence against 8x8 Contact Center and 8x8 Engage. Which capabilities land at which price is not published.
Verdict: not decidable from public pages. Trial both.
AI Receptionist
- DialPhone: Smart Virtual Concierge, a packaged product at $59 per month, 8 voices, English, Spanish and French, industry configurations, available under a HIPAA BAA on Advanced and higher.
- 8x8: we could not find a packaged AI receptionist product on 8x8’s site. That is an absence of evidence, not confirmation that none exists; 8x8 publishes AI Studio and AI-enabled self-service, and a quote may include equivalent capability. Ask.
Verdict: DialPhone publishes a named, priced product here. 8x8 does not publish one.
Supervisor AI
- DialPhone: interaction analytics, sentiment, predictive CSAT and churn detection in contact-center tiers.
- 8x8: publishes Workforce Engagement Management, Supervisor Workspace, Analytics for Contact Center and secure payment processing as named capabilities of 8x8 Contact Center.
Verdict: 8x8 publishes a longer named capability list here, including workforce engagement management and secure payment processing, which DialPhone does not publish equivalents for.
Channels and communication modes
UCaaS channels
- DialPhone: voice, SMS, video (200), online fax, team chat, AI receptionist
- 8x8: voice, SMS, video, online fax and team chat under 8x8 Work. Participant limits are not published.
CCaaS channels
- DialPhone Contact Center: voice + 20+ digital (SMS, email, web chat, WhatsApp, Facebook Messenger, Instagram, X, Apple Messages for Business)
- 8x8 Contact Center: voice + digital including web chat, SMS, email, social channels (fewer discrete platforms than DialPhone but with strong WFM integrations)
DialPhone’s consumer-channel coverage (Apple Messages, Instagram) is broader.
International reach
- DialPhone: local numbers in multiple countries (current list available from DialPhone), transparent per-minute outbound, STIR/SHAKEN attestation US-wide.
- 8x8: strong international presence, unlimited inclusion to many countries at X6+, multi-country data residency.
If the buying decision hinges on “we call India/Brazil/UK daily and don’t want per-minute surprises,” 8x8 is often the lower-TCO answer at higher tiers. For the underlying architecture decision, see our breakdown of hosted PBX vs cloud phone for global teams.
Integrations
Both integrate with the flagship platforms. DialPhone connects through supported native integrations, automation platforms and custom APIs and publishes no verified catalogue count. 8x8 lists integrations as a capability of 8x8 Work and 8x8 Engage and publishes no catalogue count on its pricing page either; the 100+ figure quoted in earlier versions of this page is not sourced and has been removed.
- Salesforce: Both native bi-directional; DialPhone with custom-object support out of the box.
- Microsoft Teams: 8x8 sells 8x8 for Microsoft Teams as a named product with a certified contact center. DialPhone supports Direct Routing; its Operator Connect status is not publicly confirmed.
- HubSpot, Zendesk, ServiceNow: Both supported natively.
Compliance
Treat neither column as proof. Ask each vendor for the artifact, not the landing page.
- SOC 2: DialPhone’s report type and service scope are not published; contact DialPhone. Request 8x8’s current report and scope under NDA.
- HIPAA BAA: DialPhone offers a BAA on Advanced and higher at no surcharge. This is a contract, not a certification. 8x8’s terms are not published; ask.
- PCI DSS: DialPhone’s assessed scope is not published. 8x8 publishes secure payment processing as a contact-center capability; ask for the assessed scope.
- GDPR: a DPA, never a certification, on either side.
- FINRA: DialPhone publishes retention capabilities; scope and attestation are not published.
- FedRAMP: DialPhone is not authorized; it has a roadmap only. Verify any 8x8 status directly in the FedRAMP Marketplace rather than from either vendor’s marketing pages, ours included.
Both vendors meet the bar on VoIP encryption and STIR/SHAKEN, DialPhone publishes its full encryption architecture in the trust center.
Who should pick which
Pick DialPhone if you need a published price to budget against, want AI transcription and summaries inside the plan, want a named and priced AI receptionist product, or want business phone and contact center on one agreement.
Pick 8x8 if you want one vendor across contact center, unified communications, CPaaS and a certified Microsoft Teams product, need published workforce engagement management and secure payment processing, already run 8x8 at scale, or are willing to negotiate pricing to your volume.
Where DialPhone is weaker: founded in 2024 against 8x8’s much longer track record, no published integration count, no CPaaS product, no certified Microsoft Teams product, no published workforce engagement management, and an AI receptionist that costs $59 a month on top of the seat price.
Where 8x8 is weaker: it publishes no prices at all. Every product routes to a quote, so you cannot budget, benchmark or check a renewal against a list price without going through sales.
