This is a real peculiar problem. I have the 3CXPhone for Android Version 2.0.1 connecting to PBXes.com. It will connect just fine by turning off the Wifi and allowing it to connect to 3g network. I also have 3CXPhone for iPhone version 1.1.5 running on an iPad3 Wifi version and it has no problem connecting on the same Wifi network. I'm not ruling out an issue with firewall but it seems odd that the same program on a different platform appears to work. Phone: Samsung Captivate Glide SGH-I927 running on Android 2.3.5 kernel 18.104.22.168 Any ideas?
