Before the advent of mobile communication devices (pagers, mobile phones), someone at a public event might be summoned over the public address system to "call your office", indicating that an urgent message was waiting for them. In this context, the phrase is used to imply that someone is unaware of important information - i.e. that their arguments are uninformed and therefore superfluous.
Your argument is wrong at every level. You should really call your office.
