I've installed Groove IP to be able to make and receive Google Voice calls on the Viewsonic v350. Outbound calls are fine, but inbound calls never ring. I have read the FaQ: http://snrblabs.com/snrb/Apps/GrooveIP/FAQ.aspx And yes, all calls are forwarded to gtalk (and only gtalk). There is no other app that could be accessing my account. And do-not-disturb is disabled. The only cause that comes to mind would be if the phone has a power-saving feature that blocks this. I have looked through all the settings, and the only power-saving controls I have is to decide how much idle time there is before the screen blanks. Do other v350 users have this problem?
