Who called from 2092450952

Called my work.  Didn't answer. No Message.

Left message about so kind of conference.

Nobody there. ID was Graven Dra. In Spanish, Dra. is the abbreviation for "Doctora" (a female doctor)

Someone else said they got calls from Dra Graven and Aust Graven (at a different number).  Does Aust mean anything in Spanish?
