I missed the initial call, and though not recognising the number, thought it may have been work related, so returned the call.
A lady with an accent (possibly Indian, or at least from the general geographic region) answered and I told her I was returning a missed call. She seemed somewhat confused, so I asked if her number was business or private, and she responded it was private and not related to a business of any kind.
I wished her good day and the call was ended at that point.
It seems somewhat suspicious when seen in relation to the other comments on this page about this number.

Got a missed call, iPhone says is Alice Springs, is engaged 24/7.
