I have installed a FreePBX on Amazon EC2. The web interface is working and I can make phone calls internally and externally but when the call is answered, there is no sound at all. When one side hand up the call, the other side still going. The flash panel is at work either. I need someone can fix the problem and let me know how it is fixed.
Or if it is easier, just reinstall it.
Please let me know whether you want to fix it or reinstall when you bid on this project. If you want, i can give you the ssh access and you can have a look at it first. Trunks will be provided for testing.
