Who I have the same questioned this topic

Hi, 

Anytime my daughters school calls me they get sent straight to my voicemail. I’ve checked to see if may have blocked their number by accident but I haven’t. I’ve saved their number in my contacts thinking that might help, it didn’t. They seem to be the only number that can never reach me directly. Nobody else that calls me gets sent straight to my voicemail. I really need them to be able to get a hold of me the first time they call. 

any help would be greatly appreciated.
