# Telephony & Analytics

Telephony integrations let a voice agent receive and place calls through providers such as Twilio, Telnyx, and Plivo.

## Add a telephony provider

1. Open **Voice Agents** and go to telephony settings.
2. Choose a provider.
3. Enter the required credentials for that provider (for example, a Twilio Account SID and Auth Token, a Telnyx API key, or a Plivo Auth ID and Auth Token).
4. Save and test the connection.
5. Assign a phone number to a voice agent.

## Transcripts and analytics

The Transcripts tab shows total sessions, average duration, sessions in the last 24 hours, full transcript detail, recording links, and event log states.

## Monitoring best practices

* Review disconnects and failed calls first.
* Check whether interruptions are handled naturally.
* Validate transcription accuracy for domain-specific vocabulary.
* Use transcripts to improve voice instructions and escalation rules.
