Does Signal use ZRTP OR OTR for encryption?

Or do Signal both? OTR for texting and ZRTP for voice calls?

In articles I read this does not become clear.

Does Signal use ZRTP OR OTR for encryption?

Assuming that you're referring to Signal, I suggest that you start here - Is it private? Can I trust it?
