# Exotel

> Connect Exotel for regional telephony operations and provider-specific routing requirements.

# Use Exotel when regional telephony requirements or existing enterprise contracts make it the preferred carrier.

## Prerequisites

* Exotel account credentials with required API access.
* Tenant telephony owner assigned.
* Approved regional routing and compliance constraints.

## Setup workflow

1. Create Exotel telephony connection for each tenant.
2. Import or provision numbers and assign labels by use case.
3. Configure callback/webhook endpoints and verify authentication.
4. Run inbound and outbound smoke tests with supervised monitoring.
5. Validate call identifier correlation between Exotel and Callaro logs.

## Field mapping guidance

* Persist Exotel call ID in CRM notes for support traceability.
* Standardize outcome mapping before enabling high-volume campaigns.
* Keep region and language tags in runtime variables for routing analytics.

## Validation checklist

* Test calls succeed for both inbound and outbound directions.
* `voice_sessions` show matching identifiers and timestamps.
* Callback retries do not create duplicate downstream records.

## Known limits

* Regional carrier quality may vary by time window.
* Number provisioning can have provider-side lead time.
* Heavy concurrency should be increased gradually.
