Ich habe das Problem, daß ich den Angerufenen nicht hören kann. Der Selbsttest (Mikrofon- und  Lautsprecher-Symbole aktivieren) funktioniert wunderbar. Die Verbindung wird aufgebaut und im SIP-Protokoll steht 180 Klingeln, dann 200 OK, dann ACK - also man sollte meinen, alles ok, aber man hört nichts.

Der Port 5060 ist angeblich offen. Also was ist da los?

Gruß, dogen


PS: Hier ist ein sipgate Debug-Log
