Who is it...I keep missing calls vm down...does anyone know who is calling? No answer when I called back.

This number called me and when I called back no one answered. When I tested this. Number no response either.     Who is this and why do they

This is a security company based in Culver City, but has offices throughout the country. For some reason all their numbers are the same. Likely calling back about a job opportunity with them (SIS.us)

I did a play for a position with SIS. Within 15 minutes of applying. I received a phone call from here so I can definitely confirm it is SIS

I'm confused. You know who called you so why did you look up the phone number? Besides, just because your call was from them doesn't mean anyone else's calls is. Or have you never heard of phone number spoofing?
