So I have a new R201, Setup 2 phone lines on it, on factory firmware Line 2 worked perfectly, Line 1 I could call in but not call out, same analog phone just moved from port to port on it. Upgraded the firmware  to 4.2.3-4. Now I can call in and it works great, but when I call out no voice carries through on either side. Any ideas on what it could be?

Hi , what is the status for this option under FSX port configuration ?
