Im having issues with my calls dropping when calling using wifi enabled calling. I'll be on a call and it will disable itself. Is anyone else having issues like this or solutions?

Yes I can't send out a call when wifi is on..it would ring once and just get silent like it stopped trying to send the call out or something

It is a T-Mobile software issue! I have experienced it with 3 phones, including the S II and the One S. Calling CS is a waste of time, they either can't afford or won't fix it. I have had a couple CS people own up to the truth about the problem, that is, that it isn't your phone. If you really complain, they will put you on an unlimited voice, if you don't have it already.

Dropped WiFi calls may directly translate to dropped packets on your access point or internet connection out.
