Pricing comparison
100-seat UCaaS team, annual billing, 12-month TCO
- DialPhone Advanced: 100 × $34 × 12 = $40,800/year
- 8x8 X4: 100 × $44 × 12 = $52,800/year
DialPhone is ~$12,000/year cheaper at the mid-tier for pure UCaaS at this seat count.
100-seat team that needs contact center
- DialPhone Advanced + CC Professional: 100 × ($34 + $95) × 12 = $154,800/year (all tiers published)
- 8x8 X6 (CC entry) + UCaaS: ~$85 + UCaaS overlap — custom quote, typically $175,000–$230,000/year
The TCO gap widens when contact center is involved because DialPhone publishes every CCaaS tier.
International calling
If the team makes 5,000+ international minutes/month across many countries, 8x8’s inclusive international at X6/X8 can be lower TCO. For lighter international use, DialPhone’s per-minute rates (published) are typically lower.
AI capabilities compared
Base-plan AI
- DialPhone: captions, summaries, sentiment included in Core. AI SMS drafting and Proactive Workflow Automation in Advanced.
- 8x8: AI captions and summaries included. Intelligent Customer Assistant and supervisor AI focused on CCaaS tiers.
Edge: DialPhone for broader native AI in the UCaaS base plan.
AI Receptionist
- DialPhone: Smart Virtual Concierge — packaged product at $59/mo, 8 voices, multilingual, industry-specific (healthcare, legal, dental), HIPAA-eligible.
- 8x8: no packaged AI Receptionist product; agent-builder capabilities via CCaaS.
Edge: DialPhone.
Supervisor AI
- DialPhone: 100 percent interaction analytics, sentiment, predictive CSAT, churn detection in contact-center tiers.
- 8x8: Supervisor AI and real-time agent assist in XCaaS CCaaS tiers; strong workforce management story.
Edge: Roughly equivalent at the top tiers; 8x8’s WFM suite is more tenured.
Channels and communication modes
UCaaS channels
- DialPhone: voice, SMS, video (200), online fax, team chat, AI receptionist
- 8x8: voice, SMS, video (100–500 tier-dependent), online fax, team chat
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 46+ countries, transparent per-minute outbound, STIR/SHAKEN attestation US-wide.
- 8x8: strong international presence, unlimited inclusion to many countries at X6+, multi-country data residency.
