Hi, I installed 3CX yesterday on my Droid. Went though some trouble stabilizing the app by adjusting the registration period to the shortest time and enabling 3G network under Integration. Great app call quality is good BUT… when I get calls from overseas landlines, they complain about hearing an echo on their end. I had my calls forwarded to my cell for a day, therefore, bypassing 3CX and didn’t have that problem. Once I took my forward off and registered my services with 3CX I stated having the issue. I don’t use Bluetooth or headphones. I had echo cancellation turned on in 3CX but it didn’t help eliminating the problem. Any thoughts anybody?
