WiFi Calling with Google Voice

[Kinolay]

Hey all, I use WiFi calling with Google Voice through an app called GrooVe IP. It works splendidly on my Galaxy Tab 2, but on EVO, it's been cutting out a lot lately, so I was wondering if anyone had other suggestions for WiFi calling apps.

I have never used my phone with VOIP - and since the Sprint signal in my home blows -
I thought I would try it out.. and 1 out of the first three calls had alot of cutting out (it was
to Sprint Customer Service, oddly enough). I am interested in a fix or alternative as well!
