# GPT-Live limitations and FAQs

> The GPT-Live limitations and FAQs now live in Settings and compatibility and the other GPT-Live guides. Each former section links to its new home.

The content of this page has moved. Supported features are in [Settings and compatibility](/gpt-live/configuration#compatibility), and the answers to these questions are in the guides linked below.

## Calls and voice

See [Calls and voice](/gpt-live/configuration#calls-and-voice) in Settings and compatibility.

## Transfers and keypad input

See [Transfers and keypad input](/gpt-live/configuration#transfers-and-keypad-input) in Settings and compatibility, and [Transfer to a person](/gpt-live/tools#transfer-to-a-person).

## Can I use an existing squad?

Squads and handoffs aren't supported with GPT-Live. See [Migrate to GPT-Live: From a squad](/gpt-live/migrate#from-a-squad).

## Can I inject commentary or control speech during a call?

See [Live call control](/gpt-live/configuration#live-call-control).

No. GPT-Live generates all of its speech. See [Speaking style](/gpt-live/design#speaking-style).

No. See [When callers change the request](/gpt-live/design#when-callers-change-the-request).
