Hi All, I've just installed 3CX PhoneSystem v12 for the company I work for. I'm having an issue with 3CXPhone for Android and 3CXPhone for Windows whilst out of the office. First off, my issue with Android. When our Android phones are out of the office, 3CXPhone for Android will connect to our 3CX PhoneSystem just fine for calls (via port 5060), however we get "Connecting..." stuck in the top left hand corner of the softphone, and we are unable to get any presence information or call history. Does this require additional port forwarding like the 3CX MyPhone did? Now, my issue with 3CXPhone for Windows. Whilst out of the office this will simply not connect, it comes up with the message that the 3CX PhoneSystem isn't available, however in the Accounts settings, the out of office IP & port are correct - I'm unable to click the icon to select office/out of office to change between modes though. Is this because it's in CTI mode? Is there a way to get it to switch to softphone mode whilst out of the office? FYI, the Firewall Checker passes just fine - ports 5060 TCP & UDP, 5090 TCP & UDP and 9000-90049 UDP are statically mapped. EDIT: I've ran Wireshark whilst opening 3CXPhone for Windows with the "Out of Office" selection in Accounts ticked and it's trying to connect on TCP Port 5000... this isn't mentioned anywhere in any tutorial, training video or the 3CX PhoneSystem v12 manual - is this correct? Any help is greatly appreciated. Kind Regards, Verta.
