AI front desk

RingCentral is easier to evaluate when the buyer wants a packaged AI receptionist path inside the business phone provider.
Global PBX
Choose 8x8 when global phone and contact-center fit matter
8x8 is a strong candidate when the buyer is comparing cloud PBX maturity, international calling, contact-center growth, and queue behavior.
Migration
Model the migration before comparing screenshots
The buyer should validate number ports, desk phones, queues, recording policy, emergency behavior, support ownership, and AI fallback.
Implementation proof checklist
- Verify whether RingCentral and 8x8 both support the exact main-number route you want to test first.
- Confirm how after-hours, overflow, no-answer, and busy-state calls are handled before sending callers to AI.
- Check recording, consent, voicemail, transfer, and CRM handoff behavior on the same plan tier the buyer would actually use.
- Run a limited pilot before porting the primary business number or replacing the existing phone stack.
Implementation take
The winning choice depends less on the logo and more on where the AI receptionist will sit in the call flow. Native AI can be faster when the provider already owns the number and routing rules. External AI can be more flexible when the business needs custom scripts, multi-system handoff, or a separate voice-agent platform.
