Key Differences
Twilio:
- Maximum flexibility
- Build everything yourself
- Complex pricing
- High development cost
- Best for: Developers who want full control
Purpose-built platforms (Retell, Vapi, Edesy):
- All-in-one pricing
- No-code/low-code options
- Faster deployment
- Lower total cost
- Best for: Businesses wanting quick deployment
When to Use Twilio
Twilio makes sense when:
- You have engineering resources to build and maintain the integration
- You need maximum customization beyond what platforms offer
- You're already using Twilio for other services (unified billing)
- Call volume is low (high per-minute costs matter less)
When to Choose Alternatives
Consider voice AI platforms when:
- Speed matters - Deploy in days, not months
- You lack engineering resources for Twilio integration
- Total cost matters - All-inclusive pricing is often cheaper
- You want managed infrastructure - No servers to maintain

Claude 3.5 Sonnet offers GPT-4 quality at 70% lower cost.
3. Optimize Call Flows
Reduce unnecessary back-and-forth to minimize minutes used.
