When he got up to answer the phone, he'd hear Ash's voice coming from the speaker, saying, "Now you have my number." There's no echo, as the Ash on the bed didn't speak.

Realizing this might be seen as odd, suddenly, Ash sat up on the bed, saying (without echoing it through the phone), "Sorry, is that alright? I should've asked..." It's just that he wanted to stay in touch with Junior after this was done, and while synths were provided with personal IP addresses, they weren't technically supposed to use them on company time.
