Apparently they speak Korean, they spoke to my grandma, but I'm not sure what they wanted.

Apparently this is a translator service.  I don't speak Spanish, but they left a message in Spanish.  At the beginning of the call you hear a woman say, "yes a food stamp appointment"  at the end of a bunch of Spanish I didn't understand, the Spanish speaker asks the lady in English is there is anything else.  She tells her "no" and then the other lady says "thank you for using our services Mrs. Bonita, have a nice day."  Strange.

Got a call from this number. Sounded like an operator possibly? A woman's voice started off by saying are you sure we called the right number? A man's voice replied with my phone number. The lady then said my name, who the heck is & my name again. The man asked if that wasn't the right person. She said no. So he said thank you have a nice day. Really weird conversation to be left on someone's voicemail...

Same as submitter named "yup." They called my work and I answered as the organization name. The lady said, "Hmm, I guess we got the wrong number? Is this xxx-xxx-xxx?" I asked who they wanted and before they could answer, they hung up.

Legitimate call from a translation service.  My wife is filipino and we were expecting a medical follow-up call, and we requested that a translator be used so that my wife could understand clearly. The way they do it is with a 3-way call with the medical professional, which would explain why some people heard a strange conversation on their voicemail with some non-english speech. I didn't recognize the number at first so I let it go to voicemail while googling the number...then the voicemail was in filipino-tagalog and I remembered that we were expecting the call.
