Has anyone tried this yet? As part of 2.3.x SIP is built into the OS as an option and I'd like to give it a shot but so far no luck (I have a VoIP account that supports outside SIP calls (softphone and such). One main question I have is the confusing default setting under "Internet call settings" for the item "Use Internet calling". The default is "Only for Internet calls". Okay, fine.... but how do I trigger an Internet call?! I can set it to "Ask for each call" but that's hardly efficient. I'm hoping either for an easier, on-the-fly option or perhaps a Power widget for switching between cell and Internet calls. Is anyone getting this to work? I have tried it by setting the above to ask each call but it won't connect to the SIP server so far even though the same settings work in my softphone. Thanks.
