Who called from 2107242705

caller did not identify and left line connected

I too receive this number. I do the same as JM.

i got a call from this number, and they stayed on the line but did not speak

When I called this number back, a voice said "this subscriber doen't accept incoming calls"

A female kept saying hello then hung up. I called back first two times went to voice mail then when I called back again and the phone just rang.
