I have a brand new G2, only had it about 1-2 weeks and I am not receiving calls while on wifi. I've tried calling my phone from the landline, it rings four times and goes to voicemail but the G2 doesn't make a sound. I can receive/send texts and make phone calls, just not get them. I've tried restarting my phone and checked my wifi settings, but I don't see any options that would cause the issues I am having. My boyfriend has the exact same phone and has no problems on our home wifi or any other wifi network. Any suggestions?
