  • Hello! I am in the process of developing a server for icq on the oscar protocol.

  • Here’s what works now:

  • Authentication

  • Messaging

  • Contact List

  • Extended and X-Status Support - Online, Away, DND, Free for Chat, Invisible, and more.

  • SQLite Database(server side)

  • Packet Logging (server side)

OOS targets ICQ equally as it targets AIM, though currently AIM is the most supported.
