Voice chat in android

Question

Im starting to create a small logical android game.
Players should communicate by voice in turn.
I want to implement a VOIP technology like discord in android studio. What should i pick for communication by voice in android?
Socket, android official SIP or something else?
And what should i do for server-side?
Im quite worked with java and kotlin both.
I appreciate for any advices.
