MediaSFU vs Retell

This page compares both options for teams evaluating AI voice operations, telephony depth, and whether to keep communications in a unified platform or split across services.

When MediaSFU is usually a fit

  • You need AI calls plus meetings, telephony, and widget surfaces.
  • You are minimizing architecture sprawl and integration overhead.
  • You prefer one platform for roadmap expansion beyond voice.

When Retell is usually a fit

  • Your roadmap is focused primarily on AI calling only.
  • You are comfortable assembling additional communication tools externally.
  • You want a dedicated voice-agent-first operational model.
