Who called from 4087258900

Multiple calls where they just leave a 2-3 minute message of background noise on voice mail.  One time I answered and when asked "who is this" a man answered "you know who this is".  Alas, it's ineffective for them.

several calls, no voice mail, no caller id

This is a number for a Hewlett Packard call center in Cupertino - Likely and employee that works there called you.
