Most providers quote one blended number like “$0.10/min”.
That makes it hard to answer basic questions:
- Did my call cost more because the model used more tokens?
- Because the call sat in silence?
- Because the PSTN leg was expensive?
- Because recording was enabled?
So we shipped Call Cost Breakdowns for Voice AI Assistant calls.
For each call, you can see the cost per component, down to fractions of a cent:
- PSTN or SIP termination
- WebRTC / media
- call control
- recording
- LLM inference (tokens, cached tokens, completions)
- TTS usage
It’s live in the Telnyx Portal and in the API/webhooks, so you can pull it into your own billing and alerts. chekout relaese notes of this feature here: Release notes: https://telnyx.com/release-notes/voice-ai-call-cost-breakdow...
