This only happens on our work wifi. I talked to our tech team and they have no restrictions on wifi calling. Our building is completely metal. Everyone doesn't have issues with their phones. Only the people who have Verizon. There is a tower within walking distance of our office. What can we do to improve our service? I have to have a working phone for my job. I really like Verizon, I don't want to have to change to another provider.
