Replacement Door bell Elite does not call our phones

I replaced my doorbell Elite due to a defective call button. When we press the doorbell Elite all my indoor chimes ring but we do not receive any phone notifications. Our three phones are Samsung, iPhone and Android. We have tried various test by ringing the doorbell while standing in the house when we all have a full network and Wi-Fi signal and still received no notifications on our phones. Does anyone know how to resolve this problem or is the replacement doorbell I received defective?
