I also had this missed call on my work phone. When tracing it, it traces back to a landline in Fairmount, IN to a communications company...but i have no idea what/who they are and why they're calling me!!!
This is the back door phone number from IU Medical Hospital Center. My wife is currently at the IU Simon Cancer Center, and this is the number that comes up on the Caller ID here at home, but it only her calling me from the hospital.
