Hallo,
ich habe exakt das gleiche Problem.
VDSL/Entertain AS mit VoIP, Speedport 921V, 3CX-Software auf Windows-PC.
Anrufe kommen an, auch für mehrere Rufnummern (ich bin von ISDN umgestiegen und habe 8 Nummern),
Anrufe nach Extern gehen raus, aber beim Gesprächsaufbau kommt dann nichts.
Ich habe auch schon auf Ports spekuliert, und die Ports für tcp+UDP 5070 (SIP) und tcp+udp 40000-40049 auf den PC geforwarded (im Router).
Leider klappt das damit auch nicht.
Kurios: Wähle ich vom 3CX eine andere meiner eigenen Nummern an, klappt auch das Sprechen/Hören.
Leider finde ich im Programm-Ordner von 3CX keinerlei Logfiles :-/
Ok, hier die "Debug"-Info:
