Meaning of "some children talk to their parents"

[chebu]

I can't clearly figure out the meaning of "some children talk to their parents" in the BT adverts discribed on the following BBC news.
Does it mean "you should call your parents more often"?
And who is Melvin in this article, Melvin Frank?

"Some children talk to their parents," huffed Maureen Lipman's excruciating grandmother at her middle aged son Melvin in the 1980s BT adverts as she threatened to come to his office and bring him a jumper and a sandwich."

The sense seems to be that Maureen Lipman played an excruciating grandmother -- Maureen Lipman's (rendition of an) excruciating grandmother.
Melvin is her fictional middle aged son.
"some children talk to their parents" implies that Melvin doesn't phone his mother (the excruciating grandmother).

Yes, the underlying message is that you should call your parents more often, especially if you're paying BT for the call.

Thank you for your instruction.

Does anyone know if " Melvin" on the article is actor Melvin Frank, or another actor?

As Raymott said 'Melvin is her fictional middle aged son.' He wasn't an actor; he had no second name, unless the scriptwriters chose to give him one. He didn't exist outside the adverts.
