Although I think it's still a long way to usable and interoperable p2p, matrix does support voice+video chat (in 1:1 chats p2p with signaling via matrix; otherwise via jitsi meet integration).

3rd party identifiers like phone numbers and email addresses can be registered and discovered via centralized service. At least for phone numbers it's not really possible decentralized.

agreed that there's a lot of work left on p2p (although 1:1 VoIP does work over p2p! :)
