[0.1.8] - 2025-09-26 ### Fixed - Finally fix this annoying issue with handshakes after webrtc disconnections! Peers will now show up in the peers list no matter what. - Old signal events will automatically be deleted from nostr relays ### Changed - NIP44 encryption at the (webrtc) data channel level - Use nip44 {encrypt,decrypt}_to_bytes() to have an encryption layer over the webrtc data channel, to enforce encryption for all voistr protocol messages (instead of using seals)

voistr: a softphone for Nostr

voistr (pronounced like: VOYST-er) is an experimental nostr p2p softphone and real-time communication agent. It uses nostr relays to exchange encrypted WebRTC signaling messages. How it works: - Peers connect to some nostr relays which accept encrypted NIP-44 events, and send an event to join a room. - Peers send NIP-44 encrypted events containing the WebRTC offers and ICE candidates. This is the handshake, made possible by the nostr relays which act as WebRTC signaling servers. - Once the offer is accepted, the WebRTC connection is established. A data channel is opened, as well as media tracks to exchange encoded (OPUS) audio data. The data channel is used for the voistr protocol, which uses NIP-44 seal events with JSON payloads. Right now there is no relays configuration and to make testing easier, voistr uses a predetermined list of relays that work well with encrypted events. If you want to try it out and help with the testing, reply here, that'd be much appreciated.
