with the new jellybean os update, seems VIBER does not work.   SKYPE is reported to crash

Is anything out there working and stable for making wifi phone calls free?

Be careful as what worked before, now seems to crash, almost as if the tablet is being made NOT TO BE a device to make wifi phone calls.   I hope that is not true, but how to explain what is happening now?

iPAD users report SKYPE is stable on the iPAD, they say far fewer updates of the iOS helps, as each time google updates its OS, which seems to be frequently, all the android apps have to be brought up to date or they dont work properly,,,,,,,maybe that is what is happening here.  Is that the case?   Is this the future for owning an android tablet.....works for a while, then not?
