# Limits

> Current API and telecom limits that are enforced by the implementation.

Only limits enforced by the current implementation are documented here.

* Call listing defaults to `limit=50` and `offset=0`.
* Call-list `limit` must be between `1` and `100`.
* Call-list `offset` cannot be negative.
* `Idempotency-Key` values must not exceed `255` characters.
* Requests captured by idempotency middleware are limited to `1 MiB` bodies.
* Carrier connections can enforce configured CPS, concurrent-call, and daily-minute admission limits.

Other limits may be resource- or deployment-specific. Avoid assuming undocumented provider or runtime limits.
