Turning off VoLTE a.k.a. Advanced Calling can solve your issue for now, but I wouldn't count on it as a long term solution. Verizon is planning to completely shut down CDMA by the end of 2019 and VoLTE will be the only choice then.
I understand it's still 3 years away, but even now Verizon already has many LTE-only towers that don't broadcast CDMA signal at all. As time goes, you will find even more of these LTE-only zones where you won't be able to make calls without VoLTE.
The only good solution is to report the LTE signal drop issues to Verizon, so they could fix problematic towers.
