-
Check integration requirements
- Basic calendar: Most services handle this

How to Switch to an AI Answering Service
Step 1: Audit Your Current Call Flow
Document how calls currently route through your business. Note your business hours, common caller questions, and any special handling rules.
Step 2: Prepare Your Business Information
Gather the information your new AI will need: business hours, services offered, pricing (if shared over phone), appointment availability, and FAQs.
Step 3: Set Up Call Forwarding
Keep your existing business phone number. Set up call forwarding to your new AI service. This can be conditional (forward only when busy/unanswered) or unconditional.
Step 4: Test Thoroughly
Before going live, make test calls covering different scenarios: appointment requests, general inquiries, after-hours calls, and edge cases.
Step 5: Go Live Gradually
Consider starting with after-hours calls only, then expanding to overflow during business hours, and finally full-time coverage once you’re confident.
Timeline expectation: Most businesses are fully operational within 24-72 hours.
Frequently Asked Questions
Are AI answering services legal in the US?
Yes, as long as they comply with TCPA (recording consent), state privacy laws, and industry regulations. Reputable vendors implement proper consent mechanisms and data handling practices.
How many languages do AI receptionists support?
It varies significantly:
- Dialbox: 26 languages with realtime switching
- Most competitors: English only, or English + Spanish at extra cost
How accurate is call transcription?
Modern speech-to-text achieves >95% accuracy on American English. Accuracy may vary with heavy accents, background noise, or poor connection quality.
Can I keep my existing phone number?
Yes. All providers support call forwarding from your existing business number. You don’t need to change your phone number or update your marketing materials.
What happens if the AI can’t answer a question?
Quality AI services can:
- Transfer the call to a live person
- Take a message and notify you
- Schedule a callback
- Provide a fallback response and capture caller info
Why do unlimited calling minutes matter?
Most AI services charge per minute, meaning costs increase with call volume or duration. Dialbox’s unlimited minutes provide completely predictable costs regardless of how many calls you receive or how long those calls last.
The Bottom Line
AI answering services help American businesses capture more leads, deliver 24/7 service, and reduce costs. Among the available options, Dialbox stands out as the only provider offering unlimited calling minutes on all plans, combined with 26-language support and comprehensive features.
For businesses with predictable costs as a priority, high call volumes, or multilingual needs, Dialbox provides the best value. Specialized needs (like restaurant reservations) or desire for human backup may point toward other solutions.
