Pricing comparison
Zoom Phone wins at the headline per-user price. The comparison flips when you price what most businesses actually need.
100-seat team, voice-only, 12-month TCO
- DialPhone Core: 100 × $24 × 12 = $28,800/year
- Zoom Phone Unlimited: 100 × $20 × 12 = $24,000/year
Zoom wins by ~$4,800 at pure voice.
100-seat team needing voice + meetings + AI + SMS
- DialPhone Advanced (meetings, AI captions/summaries/SMS drafting all included): 100 × $34 × 12 = $40,800/year
- Zoom Phone Unlimited + Zoom Meetings Business + Zoom AI Companion + compliance-ready SMS tool: ~$20 + $15 + $5 + $10 per user = $50/user × 100 × 12 = ~$60,000/year
DialPhone wins by ~$19,000 at the realistic stack.
100-seat team that needs contact center
- DialPhone Advanced + CC Professional: 100 × ($34 + $95) × 12 = $154,800/year (all tiers published)
- Zoom Phone + Zoom Meetings + Zoom Contact Center: custom quote, typically $180,000–$240,000/year
Caveat
Actual quotes depend on term length, volume, and negotiation. The load-bearing point is that DialPhone’s per-user price includes meetings, AI, and SMS; Zoom’s entry price is voice-only.
AI capabilities compared
Base-plan AI
- DialPhone: AI captions, summaries, sentiment in Core. AI SMS drafting + Proactive Workflow Automation in Advanced.
- Zoom Phone: AI features sit in Zoom AI Companion — a separate license (included free for some Zoom tiers, paid for others).
Edge: DialPhone — no separate AI license needed.
AI Receptionist
- DialPhone: Smart Virtual Concierge — dedicated packaged product, industry-specific, HIPAA-eligible.
- Zoom Phone: auto-attendant + IVR; no dedicated AI Receptionist product.
Edge: DialPhone.
Conversation intelligence
- DialPhone: native across UCaaS + CCaaS; 100 percent interaction coverage.
- Zoom Phone: AI Companion for post-call summaries; deeper conversation intelligence typically requires Zoom Contact Center or a third-party tool.
Edge: DialPhone.
Channels and communication modes
UCaaS channels
- DialPhone: voice, SMS (TCPA/10DLC compliant), video (200 participants, AI captions), online fax, team chat, AI receptionist
- Zoom Phone: voice + basic SMS. Video meetings require a separate Zoom Meetings license. Fax via partners.
CCaaS channels
- DialPhone Contact Center: voice + 20+ digital (WhatsApp, Instagram, Apple Messages, Facebook Messenger, X, SMS, email, web chat)
- Zoom Contact Center: voice + digital channels, separate product from Zoom Phone
SMS compliance
DialPhone’s business SMS is built for TCPA, 10DLC registration, STOP-keyword handling, and opt-in tracking. This matters for:
- Healthcare appointment reminders
- Financial services notifications
- High-volume marketing campaigns
- Regulated-industry outreach
Zoom Phone’s SMS is basic and not designed for compliance-heavy messaging at scale.
Integrations
Both integrate with the flagship platforms. DialPhone ships 500+ pre-built; Zoom integrates deeply inside its own Zoom App Marketplace.
- Salesforce: Both native bi-directional.
- Microsoft Teams: DialPhone Operator Connect certified. Zoom for MS Teams is limited.
- Zoom Meetings: DialPhone integrates (calendar, click-to-join). Zoom Phone is native.
Compliance
- SOC 2 Type II, GDPR, PCI-DSS, FINRA: both
- HIPAA BAA: DialPhone Advanced+ no surcharge; Zoom requires enterprise tier and separate BAA request
Who should pick which
Pick DialPhone if you want AI in the base plan, compliance-ready SMS, unified UCaaS + CCaaS on one platform, a dedicated AI Receptionist, or HIPAA BAA included on Advanced. Also pick DialPhone if the bundled TCO (voice + meetings + AI + SMS) is the procurement metric.
Pick Zoom Phone if you are fully Zoom-standardized, your primary need is cheapest PSTN with minimal SMS/CCaaS requirements, or you already pay for Zoom Meetings + AI Companion and want the minimum additional cost.
