I'm checking out the IP Desktop Softphone for Android and iPhone, but it looks like I'm missing something.
When installing the iPhone app, there is no settings button. I can't find any way to configure the app to connect to our PBX. Our wifi network uses a different subnet as the PBX, but the PBX is reachable from it.
I've tried adding DHCP reservation with option 66 to point to the TFTP server for that specific phone, but that doesn't seem to do anything. Clearly I must be missing something, but what? If I search the internet, I can't find any information regarding the configuration, all info I can find assumes that the phone has already registered with the PBX.
When using the Android app, I have a gearbox/setting icon at the bottom where I can specify the TFTP server address, and I connects and registers as expected.
