Can anyone explain a setting for me, please?
It's "Use Internet Calling" and it's to be found in Settings / Call settings, right at the bottom.
The options are:
For all calls when a data network is available
Only for internet calls
Ask for each call
I cannot find any mention of it in the on-screen Help files or in the downloadable pdf user manual.
Now I'd ASSUMED it meant (assuming I have selected option #1) that if I was within range of my Home WiFi, any normal calls (incoming or outgoing) would somehow be routed through that, rather than using the normal 2G/3G phone network..... but now I'm not so sure.
There's a setting above it, to log into a "SIP" account for internet calls, I have no idea what a SIP account would be and I'm not sure if one is required to do the job I just described.
I haven't foiund any way to test if it is happening or not, either. I tried switching to flight mode and then turning Wi-Fi back on, but was unable to make any calls.
The main reason I started investigating is that my wife has a poor signal at home on her Samsung Galaxy Ace and I cannot find any similar menu items on her phone at all. But now I'm intrigued about what it's actually doing on mine (if anything!)
