1:1 comparison · Verified August 27, 2026 Zoom Phone is PSTN calling inside a platform many teams already run. DialPhone sells business phone and contact center under one agreement with published per-user and per-agent pricing. This head-to-head compares the two on structure, AI, SMS, contact center and fit.
A limitation this page states rather than papers over. Zoom prices Zoom Phone per country, and we could not access Zoom’s US pricing view from our location at the time of checking, so this page does not quote US Zoom Phone prices. Every Zoom price that appeared in earlier versions has been removed rather than re-estimated. Get current figures from zoom.us/pricing/zoom-phone with your own country selected. Structural facts below are taken from that page, checked 27 August 2026.

Pricing comparison
Only the DialPhone side of this comparison can be costed here. Zoom’s US per-user figures were not verifiable from our location, and this page does not estimate them.
100-seat team, 12-month cost, DialPhone list prices
- DialPhone Core: 100 × $24 × 12 = $28,800/year
- DialPhone Advanced: 100 × $34 × 12 = $40,800/year
- DialPhone Advanced + Contact Center Professional: 100 × ($34 + $95) × 12 = $154,800/year
Earlier versions of this page presented three Zoom cost models: $24,000 a year for voice, roughly $60,000 for a bundled stack, and $180,000 to $240,000 with contact centre. None of those figures was sourced to Zoom’s current pricing page and all have been removed.
What to price on the Zoom side
Zoom sells Zoom Phone, Zoom Meetings and Zoom Contact Center as separate products, and states on its pricing page that all Zoom Phone add-ons require a paid base plan. Published Zoom Phone add-ons include a Customer Engagement Pack, additional phone numbers and international calling. If your requirement spans calling, meetings and contact centre, price all three lines from Zoom, then compare the total against the DialPhone figures above. The structural point stands without invented numbers: DialPhone bills one line, Zoom bills several.
AI capabilities compared
Base-plan AI
- DialPhone: AI captions, summaries, sentiment in Core. AI SMS drafting + Proactive Workflow Automation in Advanced.
- Zoom Phone: Zoom bundles an AI Productivity Suite with Zoom Phone plans and describes the entry tiers as having limited AI capabilities. Deeper AI sits across the wider Zoom platform.
Verdict: DialPhone publishes AI captions and transcription from its entry tier. Zoom’s AI is bundled but tier-limited, and its depth depends on what else you own across the Zoom platform.
AI Receptionist
- DialPhone: Smart Virtual Concierge, dedicated packaged product, industry-specific, HIPAA-eligible.
- Zoom Phone: we could not find a packaged AI receptionist product for Zoom Phone. That is an absence of evidence rather than confirmation none exists; ask Zoom.
Verdict: DialPhone publishes a named, priced AI receptionist product. Zoom does not publish one for Zoom Phone.
Conversation intelligence
- DialPhone: native across UCaaS + CCaaS; 100 percent interaction coverage.
- Zoom Phone: Zoom bundles an AI Productivity Suite with Zoom Phone plans and describes the entry tiers as limited; deeper conversation intelligence sits elsewhere in the Zoom platform or in Zoom Contact Center.
Verdict: DialPhone bundles conversation intelligence into the seat. Zoom spreads it across products, so the answer depends on what else you already own from Zoom.
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 connects through supported native integrations, automation platforms and custom APIs; Zoom integrates deeply inside its own Zoom App Marketplace.
- Salesforce: Both native bi-directional.
- Microsoft Teams: DialPhone Direct Routing; Operator Connect status not publicly confirmed. 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 calling, meetings, SMS and contact center billed on one line rather than as separate Zoom products, want a published US price you can read without a country selector, want AI captions and transcription from the entry tier, or want a HIPAA BAA offered on a published mid tier.
Pick Zoom Phone if you are standardised on Zoom Meetings and want calling in the same platform and admin console, need country-specific calling plans or the Global Select plan covering over 40 countries at one flat per-user price, or already pay for Zoom’s AI across the platform and want the lowest marginal cost.
Where DialPhone is weaker: it adds a second vendor for a Zoom-standardised organisation, has no equivalent to Zoom’s per-country calling plans or Global Select, was founded in 2024, and charges $59 a month extra for its AI receptionist.
Where Zoom Phone is weaker: calling, meetings and contact centre are separate products with separate bills, Zoom states that all Zoom Phone add-ons require a paid base plan, and its pricing is country-locked, in some markets to a single currency, which makes cross-border comparison harder than a single published list.
