Quite Possibly

Quite possibly, the most least effective forms of human communications is trying to talk to a baby over the phone. If the baby can't speak to you in person, what reaction do you expect to get over the phone? It goes:
GLowing Grandma: Hi, hey, , hey
Baby:
Glowing Grandma: what're you doing, hey, (then a little louder, cuz volume will teach the baby to talk), HIIIIIEEEE, HEEEEEYYYEEEEE
Baby:
Mother: Guess he doesn't feel like talking now.....

Yes, useless communication......
