Dialer Hangs if LTE signal is weak.

I have updated to the 47E buil and I do have a better signal with the 98R radio, however ever since upgrading to 5.1 with VoLTE enabled on Tmobile if I have a weak LTE signal sometimes when I dial a number the dialer hangs and it just says dialing, if I attempt to hang up it gets stuck on Hanging Up and it does nothing:(. I can't dial or hang up and it says there is a call in progress but there isn't one and the only option is to reboot my phone :confused:. This is extremely annoying. I have turned off the VoLTE since then. When I have a good LTE signal it works great but this is a major issue for me...

Has anyone else noticed this problem?
