Hallo, ich versuche vergeblich, eine direkte VoIP-Verbindung zwischen 2 Rechnern mit festen IP-Asressen im LAN herzustellen. Auf beiden Rechnern ist Phoner 2.10 installiert. SIP ist konfiguriert, Profil: d, Lokaler Port: 5060, bevorzugte Verbindungsart: UDP, API: SIP, keine Stille-Erkennung, sonst alle Felder leer. Beim Versuch, eine Verbindzng aufzubauen, wird im Statusfeld "486:Busy Here" ausgegeben.

Das kann natürlich nicht die Lösung des Problems sein. Ich bin ratlos und für jeden Hinweis dankbar. Grüße Norbert
