telephoneaphobia 

When a man is afraid to have a friend with benifits forgets how to dial the phone out of fear that the girl wants more.

He don't have to have to have telephoneaphobia it ain't like he's my boo!

Telephonophobia

Telephonophobia, in plain terms, means fear of telephones but it’s not the physical telephone that haunts. It includes fear of receiving or making a call. So, when it comes to make or receive a call, you get nervous and sweaty along with shivers. You avoid calls and ask others to do it for you.

Oh shit it's the boss on the phone, mate can you answer it and tell him I have food poisoning? (A real case of telephonophobia)
