LAUSD Superintendent Ramon Cortines : ‘This is a rare threat, we get threats all the time.... What we are doing today is no different to what we normally do, but we are doing it on a mass scale’
No, not phone call.
Electronic message - E-MAIL, to be exact.
Reporter on FoxNews specifically said a phone call to a school board member is what triggered this.
McCallum did repeat that the threat (email or phone call not specified) did contain a specific location and time and that is why they consider it credible.

I suppose the phone call could have been in the form of a text message or email to a smartphone.
Hemmer just said they do not know the exact format/transmission of the threat -- but it was electronic.
