Retell AI - Pros & Cons
Pros

- ✓Modular pricing with 15+ LLM options and 6 TTS providers lets you precisely optimize cost-quality tradeoffs per agent
- ✓Free SIP trunking eliminates per-minute telephony charges — significant cost savings for high-volume deployments

- ✓Webhook-based function calling enables real-time CRM updates, appointment booking, and database queries during live calls

Cons
- ✗No self-hosting option — all voice data flows through Retell's cloud infrastructure, which may not meet strict data sovereignty requirements
